Please observe the special instructions for their protection. Incorrect handling can damage the unit and cause the invalidation of the warranty. Minimum safety precautions against electrostatic discharge:
Establish earth contact before you touch the unit. For example, touch the earthing screw on the unit. even better: Use an antistatic ribbon and earth yourself permanently for the time you handle the unit. Avoid unnecessary contact with the unit connectors and assemblies inside the unit. Only open the unit if the operational settings (as described in the manual) expressly require this. Use antistatic tools for the setting of the unit. (Warning: Do not touch life-threatening voltages with these tools). Do not store unit and components without protective packaging. Only remove unit and components from the packaging immediately prior to installation. These notes are not sufficient to guarantee complete protection from electrostatic discharges! We recommend the use of suitable protective equipment. Page 7 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH Safety prec autions Safety Instructions The system described in this manual is for exclusive operation by trained employees. Only qualified personnel that know the po-
tential dangers involved should perform the installation, settings, maintenance and repair of the units used. Safety Documents This OIS-L system was designed, tested and supplied in perfect condition according to docu-
ment IEC348 Safety Requirements for Electronic Units of Class 1. Operational Safety The correct and safe use of these systems as-
sumes that operating and service personnel fol-
low the safety measures described in the man-
ual alongside the generally acceptable safety procedures. If there is a possibility that safe operation cannot be guaranteed the system must be switched off and secured against accidental use. Then the service unit responsible must be informed. Condensing Water / Change of Temperature Moving the systems from a cold to a warm envi-
ronment could lead to dangerous situations due to condensation. Therefore it must be ensured that the system can adjust itself to the warmer temperature. Opening the Cov ers or the Housing Do not open the housing. There is no need to open the housing in order to set the series 77 reader devices. The unit does not have any in-
ternal setting elements or displays. All settings are performed via the test terminal port. The internal parts of the unit, especially the printed circuit boards must be protected against oil, moisture and air contamination. When re-
moving the protective covers make sure that no mechanical damage of the sensitive electronics occur or metal objects (nuts, washers, etc) fall into the unit. Therefore do not open the unit. Earthing Before establishing any connections the housing of the system must be earthed. Connections / Power Supply The supply circuits must comply with the condi-
tions set out
(see EN60950). The signal circuits must comply with the condi-
tions set out
(see EN60950). the SELV circuits the SELV circuits for for Use screened cables for the power supply. This is the only way to achieve the prescribed EMC. During maintenance damage could occur if printed circuit boards or cables are connected or disconnected whilst the power supply is still on. Therefore only work on the connection and the components when they are not live. SELV Safety Extra Low Voltage Protective meas-
ure against dangerous body currents, formerly: pro-
tective first voltage range EMC Electromagnetic Compatibility, Fuses Only experts who are aware of the dangers in-
volved may replace the fuses. It must be en-
sured that only fuses of the required current rat-
ing and the correct type are used for replace-
ment. The use of repaired fuses and/or short-
circuiting the fuse holders is prohibited. Spare Parts We recommend that only personnel, original products, spare and replacement parts author-
ised by Baumer Ident be used for installation, service and repair. Otherwise Baumer Ident does not accept any responsibility for materials used, work carried out or possible conse-
quences. Electrostatic Discharges Semi-conductors of the type MOS or CMOS as well as two-pin types and precision resistance are extremely sensitive to ESD. All components, printed circuit boards and auxiliary systems should therefore always be classed as sensitive to electrostatic discharges. Before opening the cover the unit should be placed onto an ESD-protected surface. As with all work on modern electronic modules the use of ESD clamps and ESD mats during work on the unit is recommended. Sufficiently protect all printed circuit boards that were removed from the unit from dam-
age. Baumer Ident GmbH Read/Write Short R ange System Manual Page 8 of 59 Safety prec autions Observe all normal precautions for the use of tools. Use ESD-protected packaging material. Never use measuring units with low impedance for measuring or testing systems with semi-
conductor components. Never use high voltage testing units or dielectric test units to test sys-
tems with semi-conductor components. When it becomes necessary to check the iso-
lating properties of the field wiring, the assem-
blies (electronic units and sensors) should be disconnected. Earth the test units. Baumer Ident does not accept returns of prod-
ucts where the regulations concerning the ESD precautions and protective packaging materials were not followed.

tion system, generally referred to as RF-ID. It is intended for applications in logistics sys-
tems. The OIS-L standard system consists of three units:
Antenna for energy and data transmission Transponder with a Read/Write memory Central unit with analogue and digital data processing The OIS-L Series 77 Standard Range RF-ID system is a family of products that have been developed to meet the market demands for in-
dustrial identification products with a high de-
gree of modularity to solve a variety of tasks in logistics and other applications. System overview The signals are detected (demodulated) by an analogue circuit and passed on to the digital circuitry. Here the microprocessor and related software checks the data transmission, con-
verts the code and in the event that the trans-
mission was read the code is made available to the host computer for further data process-
ing. The chip requires a field voltage of about 3,5V to become active. This tension is induced by the alternating magnetic field. The data trans-
mission is done by means of an amplitude modulation, using the Manchester code. The detection of 32 full oscillations, indicates that one bit has been transmitted. This kind of data transmission is very insensitive to external disturbances from other electrical equipment The OIS-L-system is a passive RF-system in the lower 125 kHz frequency band (ca. 125 kHz). The programmable data tag consists of a CMOS-
Chip with an EEPROM memory and a coil. The reader, is made up of all of the components re-
quired for the transmission of energy and the re-
ception of the demodulated signals from the tag. The energy is transmitted to the tag via an alter-
nating magnetic field, analogous with the principle of a transformer. If a transponder comes within the useful area of the magnetic field it receives the required energy it is then ready to receive commands, to either store a code in memory or to send the contents of all or a part of the memory. and is particularly suited for industrial applications. The reading distance is dependant on the power of the magnetic field and the exact frequency tuning (compare radio reception). Normally an up-

Although the majority of data tags would function in combination with any of the antennae, we have grouped them into logical groups highlighting the desired combinations, that enable the user to achieve tled information relating to the reading distances for the various antennae/tag combina-
tions are shown later in this document. per limit for this technology is set at 1 meter
(40") however for small tag/reader combina-
tions these values are in the range 1 to 30 centimetres (0.5" - 12"). 3.3 Typical System Configuration The OIS-L Series 77 Standard Range Read/Write system consists of the central unit 77LA04-X and one or two short range anten-
nae (selected from the 77 Series Antenna range). The data tags can be either the fixed code type (series 76) or the Read/Write type
(series 77): The Read/Write data tags come in two different memory sizes, 256 bit or 2 kbit. The following diagram shows an overview of the standard products in the Read/Write sys-
tem. The data tags come in differing shapes, sizes, and housing materials. Some are coin-
shaped; others are packaged in PVC and are 76LA02-x 76LS61 Frame Antennae 77LS04, 77LS09 are also a-

Explanation In order to have a structured part numbering system the following definitions apply. An existing part numbering system is already in circulation e.g. 77 LA04. These names are easy for the existing user to identify, however they are not always unique to a particular product. An example would be the part number 77LS03 this identifies an antenna but the version or tuning of this antenna is not included in this part number. Field No. Description Possible Values

cation system OIS-L has been developed with re-
spect to the regulation EN 300330 class 2. Thus, passive antennae connected to a central unit is the basic system concept. Antennae can be easily designed for customers request. No additional approbation or certification of the complete sys-
tem is necessary. By the technique of multiplex-
ing, some central units can handle more than one antenna. The high protection class of all central units make them ready to use within an industrial environ-
ment. Whether outdoor-use, rain or dust, the system always operates reliably. Direct mounting on vehicles in particular lift trucks is possible. Various bus interfaces including high layer soft-
ware facilitate the connection to host systems for engineers. The intelligent configuration software provides easy installation and system start-up by the customers qualified personnel. A special Baumer Ident feature is the possibility of auto-
matic on-site antenna adjustment by software. This enables the optimisation of already installed systems whereby the environment is automati-
cally considered by the adjustment process. The system works with EM4102, HiTag 1 and Hi-
Tag 2 chip transponders. 4.1.1 Common Technical Details of Central Units 4.1.1.1.

Common parts of every central unit Power supply The processor board contains the power supply in the form of a galvanically separated DC-DC converter, operating between 18 and 36 V DC. The converter provides the different internal ten-
sions for the analogue board, the COM-module and ancillary electronics. This converter is pro-
tected against polarisation errors. The digital inputs and outputs (I/Os) are opto-
coupled. The processor of the central unit handles the com-
mands from a host computer (PC or PLC) as well as the data transfer to and from the antenna. This electronic circuitry consists of the following compo-
nents:
Micro controller C515A-L24M or Micro controller 80C515 System memory 32 kByte RAM Analogue module The analogue module handles the energy transmission to the tag over the antenna and the demodulation of the data signals received from the data tag. The analogue board receives con-
trol signals, required for the communication with the data tag, from the processor board. The board contains two separate, identical circuits to handle two separate antennae. Programme memory 64 kByte EPROM This memory contains the programme for the sys-
tem self-test and the operating system This memory serves the purpose of storing the configuration data. The data may be altered via the terminal Serial EEPROM 32 kByte Processor board A non-galvanically separated RS232 interface is provided for the configuration of the central unit. Digital I/Os The two galvanically separated digital inputs have a permissible input voltage of:

`1'-signal 16 ... 36 V (max. 10 mA)
`0'-signal -2 ... +2 V The above is valid when using an input resistor of about 3k . The two galvanically separated digital outputs have an allowed switching voltage of:
10 ... 36 V / 0,05 A (50 mA) See also the following section for further details. Terminal The terminal interface is used for system con-
figuration and diagnostics purposes. It is in-
tended to be connected to a personal computer running a terminal emulation software. The ter-
minal is a RS232 interface. It is not galvanically separated (not opto-isolated). 4.1.1.2.2. Communication modules The communication modules make up the sys-
tem interface between the reader and a host computer (PC or PLC). The system has automatic interface detection so that no setting is necessary. 77COM-SER The communication module 77COM-DP integrates a Profibus-DP interface with maximally 12 Mbaud in the memory area of the processor. 77COM-IBS The serial communication module 77COM-SER integrates a UART of the type 16C550 as a se-
rial interface in the respective memory area of the processor. The driver-ICs are fed from a DC/DC converter via galvanically separated opto-couplers. They provide the following host interfaces:
upper connector IBS-OUT, lower connector IBS-IN Interbus module and integrated SUPI3 controller with 10 IBS words IN and 10 IBS words OUT. Con-
nection with the OIS-L controller is via a serial in-

Schematic of bus termination The cable shield must be connected to the pro-
tective ground to prevent EMC disturbances from reaching into the central unit. The power supply to the termination resistors on pin 6 is only intended for that purpose and thus restricted to 10 mA. It is important that the connectors at both ends of the Profibus-DP cable are equipped with termina-
tion resistors. If this is not the case there may be problems with the transmission. Baumer Ident GmbH Read/Write Short R ange System Manual Page 24 of 59 Sys tem Components 4.1.2.2. System Diagnostics LED Description On the rear side of the controller there are 5 LEDs situated as shown in the diagram below:
LED Layout on backpanel No. Signal name Function 1 2 3 4 5 A1 Antenna 1 active When lit, the antenna is active, executing a Read/Write command with a tag or the controller is waiting for a tag at this antenna (automatic Read/Write mode) A2 Antenna 2 active ditto with antenna 2 R RUN mode flashing 1/2s Tx Transmitting data Rx Receiving data A flashing LED indicates that the controller is running. When entering the Monitor the LED stops flashing the last LED state remains active until the normal program operation con-
tinues. Note: the Monitor program stops automatically on missing terminal inputs after about 30 seconds and the normal op-
eration continues. The controller sends data via the host port (Serial or Pro-
fibus) the LED is switched ON just before the data is put into the output FIFO buffer and switched OFF when the last character of data is placed in the communication device. When the controller fetches a complete command from the communication device the LED switches ON. The LED switches OFF when the message receive has completed. With Profibus DP the LED switches ON at any change of the controller inputs state (CTL-octet) and switches OFF when the decoded command transfer to the command execution module (command parser) has completed. Hint:
A flickering Rx-LED on Profibus without any flickering of the Tx-LED (for responses) indicates that the host does not handle the command handshake bits correctly in this case refer to the section in this manual describing the CTL Bit Handshake Protocol.

Baumer Ident GmbH Read/Write Short R ange System Manual Page 36 of 59 Sys tem Components 4.2 The Antennae The system OISL has been developed with re-
spect to the European regulation EN300330/Class 2. This class is intended for systems with cus-
tomised antennae. The regulation requires an approval for the central unit only whereas antennae of class 2 systems are not subject to any approval or permission re-
quirements. These antennae are passive; in particular any OIS-L antenna is only the inductive part of the systems resonance circuit. There are two different types:
AN.76.SR.xx.yy: These antennae are only for compatibility with an older Baumer Ident inductive identification system, 76LA01/xx AN.77.SR.xx.yy: These antennae are stan-
dard use for the Baumer Ident OISL short range units ZE.77.Sr.xx.yy. system central with The different antennae have been designed with respect to a wide variety of applications. In gen-
eral antennae have to be used in an air environ-
ment. For mounting in close proximity to metal please read the appropriate chapter in this system man-
ual. Specifications about reading distances and recommended transponder types are also given in this system manual or in the OIS-L transponder data sheet LD.0306.EN. Special antennae for mounting directly onto metal are available. The antenna transmits energy and data signals to and from the data tag. The coil and necessary electronics are enclosed in a sturdy frame hous-
ing made of polystyrene. The frame is fully sealed and is protected to an IP67 rating. On a standard frame antenna the housing ac-
commodates four mounting holes size M6 for screws. A mounting kit (optional) containing brackets and vibration dampeners is available to facilitate the simple and correct mounting of the antenna.

eral antennae have to be used in an air environ-
ment. In difference to 77LS05 the antenna 77LS06 has an internal ferrite rod while the housing is identi-
cal. Thus, the antenna field has a special shape which influences reading distance an maximum passing speed of a transponder. The antenna 77LS07 is designed for direct mounting onto metal. 4.2.2.1. Common data for all spe-

Basic Definitions The memories of the various read write tag types
(77LDxxx) are physically organized in pages. One page contains 4 Bytes or 32 Bits of data. Only a page can be accessed as a smallest unit. The Read/Write data tags memory size allows to ac-
cess 4 to 48 pages (16 to 192 Bytes, 128 to 1536Bit) of user pages depending on the specific tag type. Byte access is supported only on the base page read, modify byte, page write back. Read-only tags (76LDxxx) are not organized in pages. The memory contains a total net size of 5 Bytes (40 bits) of fixed sized programmed data. The memory size including extra synchronization bits and parity bits is 64 bits. 4.3.1.2. Read Only Tags The 76LDxxx read only tag family offers a mem-
ory size of 64 bits. These bits are transmitted se-
quentially while the tag is in the active antenna field. 24 bits are used as the message frame with the SYNC-Header, parity bits and stop bit. 40 bits are used as the UNIQUE ID. Only these 40 bits are delivered to the user. The logical memory map on the data tag looks like the following:
1 2 3 4 5 ID Byte [MSB]
ID Byte ID Byte ID Byte ID Byte [LSB]
40Bit unique. (Read only)
[64 Bits with sync bits and parity bits]
Tag data logical memory map The TAG-ID has a length of 40 bits packed into 5 bytes. Each byte is transmitted as 2 hexadecimal ASCII characters 0...9, A...F. The higher order nibble is sent first following the lower order nibble. With read-only tags there is no need to set any page numbers since the tag has a fixed code length and is not divided into pages. By offering the opportunity to handle various tag types it is necessary to provide information on how to access read only and read write tags. This overview gives a short overview about different tag types and their special access parameters.

The 256 Bit type contains 8 pages, each having 32 Bit. The first page contains the unique serial number of the tag, the next three pages are reserved and the remaining 4 pages are available for user data. Optional read only configuration A specialty of this tag type is that it can mimic a read only tag. Using this feature PREDEFINED or multiple READ ONLY TAGS with the same ID may be produced that are completely compatible to the Series 76 tags. Series 77LDxxx-2yy data tags may be used in a mixed environment with 76LDxxx tags. This tag function must be set-up in factory or re-
quires special controllers and controller software at the customer site. The data on the tag has the following layout Page #

The main differences are the larger amount of pages that can be read by an atomic command (up to 16 pages max.) and different page start ad-
dresse s of user data area and its greater size. Baumer Ident GmbH Read/Write Short R ange System Manual Page 42 of 59 Sys tem Components accessable.

Enabling the new system to meet all of the planned project cri-
teria. When selecting the correct OIS-L compo-
nents for an application, there are a few more items to be considered:
The env ironment Is it free from metal around antenna and data tag Electrical noise close to the antenna -or data tag Humidity Temperature Aggressive media Vibrations, shock Required distance between antenna and data tag Writing data to the tag Number of write cycles per time unit Dynamic Static The antenna field runs concentric with the coil windings. Hence the field is stronger towards the centre of the antenna, where the fields from all four sides coincide. A certain field also occurs on the outside of the antenna frame. Thisis the rea-
son why the field close to the antenna surface is larger than the actual coil winding itself. The fol-
lowing graph shows a typical antenna field form and spread when both the antenna and data tag are free from metal influences. 5.3 Useful antenna field It is important to distinguish between static and dynamic applications. The tag needs to be within the active field for approximately 80-150 ms (de-
pending on tag type for one page or read only Code-ID) to guarantee a correct code reading or data programming. The higher up on the lobar antenna field form the tag passe s the antenna, the shorter the useful field gets resulting in a re-
duction of the max. passing speed possible. The reading range achievable depends on differ-
ent factors, e.g. antenna type, data tag position, and interferences in the environment. Typical val-
ues achievable are listed in the following tables under conditions as stated in the respective table. Passing speed required Amount of data to be transmitted Max. out of centre deviation ( mm) Page 45 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH Hints on Installation and System Design Antenna field Communication range definition for static and dynamic application Note The tags of the same size e.g. 77LD03-xx have the same communication distance; hence not all variants are displayed in the table. Set-up to establish Read/Write distances The various reference numbers in the previous graph have the following meanings:
Hmax This is the maximum distance pos-
sible between the antenna and the data tag where the field strength is high enough to power up the data tag. Since the diameter at this point is close to zero, it can only be used for static applications. Ha Hm W D This is the main field and should be used for dynamic applications. The max diameter D indicates the up-
per limit for dynamic applications. For maximum allowable passing speeds please refer to the appro-
priate manual section. Defines the distance between a metal surface and the antenna. For optimal system performance it is essential to keep a minimum dis-
tance to any metal surface. The W stands for the maximum al-
lowable offset from the centreline, having just a minor influence on the passing speed in dynamic applica-
tions. The maximum diameter D indi-
cates the upper limit for dynamic applications. Baumer Ident GmbH Read/Write Short R ange System Manual Page 46 of 59 Hints on Installation and System Design 5.3.1 Width D and W and reading range at distance Ha 76LD020 76LD030 76LD050 76LD060 76LD100 76LD500 Reader D, W [mm]

Baumer Ident GmbH Read/Write Short R ange System Manual Page 48 of 59 Hints on Installation and System Design 5.3.4 Static applications From the above statement it is evident that the upper part of the field may only be used in static applications. Local environmental influences may have an adverse effect on the achievable Read/Write distances. It is therefore vitally im-
portant to measure the distances on site with the equipment to be used, to avoid problems in the field. A particular problem to look out for when consid-
ering an installation, can be caused by the close proximity to strong fields generated from AC-
servos. Note! Watch out for possible disturbances in the area surrounding the antenna. 5.3.5 Dynamic applications For dynamic applications For dynamic applica-
tions only the lower section of the lobar field should be used. This is demonstrated in the graph given on the previous page. A second important factor to consider in dynamic applications is the off-centre deviation. The corri-
dor W in the graph indicates the maximum devia-
tion +/- from the antenna centre line. The field varies slightly with the data tag size. For practical purposes a value between 0,4 and 0,5 D can be used as a start value. If the data tag extends beyond these values, the contact length with the active field gets shorter, reducing the achievable passing speed. Do not forget to consider the deviation from the antennas centre line!
5.4 Calculating the Passing Speed The achievable passing speed depends on the size of the antenna, data tag and the number of Bytes to be transferred. The contact time for reading the fixed-code serial number i.e. the time the data tag is required to be within the useful area of the antenna field is about 140 ms. This gives a simple rule-of-thumb to calculate the maximum passing speed for a particular an-
tenna/data tag combination. Desired passing speed in mm/ms 100 =
Length of useful antenna field required in mm. Example passing speed = 30m/min (100 ft/min) This equals 0.5 mm/ms 100 = 50 mm useful antenna field length. 100 ft/min = 0.02"/msec. 100 = 2" useful antenna field length The tables before show typical values for different antennae and different tags used. The values have been established from measurements from several tags and the average value has been taken. Temperature variations and production tolerances may produce values that differ from the above by 20%. Hence we recommend to perform tests with the equipment on the site in question, to es-
tablish the Read/Write distances and passing speeds achievable in the actual application. Note! Local conditions may affect the Read/Write distances achievable. Production tolerances and temperature changes may also cause a deviation from the values in the table!

Reader Host (PC or PLC) The communication time required between the central unit and the host depends mainly on three factors:
Type of communication
Cycle time of the host
Software used The communication can be split into three main steps as follows:
1) A command is prepared and executed in the host and transmitted to the central unit. 2) The central unit performs the instructions i.e. writes data to and/or reads data from the tag. The data exchange between central unit and tag starts as soon as the tag has entered the active antenna field. The data received from the tag is evaluated and verified and subsequently stored in the mem-
ory of the central unit 3) The host polls the central unit and the code stored is transmitted to the host. 5.4.2.1. Serial communication time The communication between the host, the central unit and tag is asynchronous at a standard trans-
fer rate of 9.600 Bps. This is the base for calcu-
lating the amount of data that may be transferred during the time the tag is within the active field of the antenna. For the serial and Interbus-S con-
troller versions the transfertime via the serial link must be added to any read / write execution times. The Profibus-DP versions provide a faster internal transfer rate and must be handled differ-
ently. Read command:

It is only possible to show the graphical representation of the corre-
lation for typical combinations of tags, antennae to help the user to estimate the key limits of this scheme. The following information only applies to data tags within the field with the boundary W and W of the main field H a short long 5.4.3.1. Component selection Selecting the best antenna, tag combination for a given application is executed as an iterative proc-
ess. Various different parameters must be varied to get a proper component match to the specific application and environmental conditions. The following steps must be taken to determine the required parameters. 1. Select the antenna for the required read/write distance antenna tag from tables:
Operational Read/Write range Ha 2. Check the antenna selected for matching against the table:
Width W of reading range at distance Ha 3. As result the Tag-Type and the Antenna are selected. Page 51 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH Hints on Installation and System Design 4. The given antenna size D and the Tag di-
ameter give the available physical reading length as result. The parameter D can be determined from ta-
ble:
Width W of reading range at distance Ha Now all parameters referring the available length of the read/write area Sproc_len are determined. 5. With the next step the available time for communication with the data tags is calculated from the application specifications. The user must determine the number of pages to transfer between antenna and tag. With the parameters tag type and number of pages to transfer over all, the user can calculate the amount of time Tproc_len required to proceed. 6 The best case passing speed v opt_proceed is calculated (using the general formula v = s/t):
v opt_proceed = Sproc_len / Tproc_len Example:
The following conditions are given by the appli-
cation specifications:
Controller 77LA04/2-SER with one antenna. Required read range ~50mm (distance tag / an-
tenna), minimum distance 30mm, max. distance 70mm.

ceptable Step 4 Check read width W The antenna 77LS02 has an effective coil di-
ameter of 120mm (150mm 2*15mm), using a data tag with an effective coil diameter of 30mm. The estimated resulting field size is:
W = Sproc_len = 150mm 30mm = 120mm. See the following drawing for details. D Dta g Dta g Dta g Estimate antenna reading area using given antenna diameter and tag diameter. W Estimated coil diameter Step 5 Estimate the time required for Read / Write operations:
Baumer Ident GmbH Read/Write Short R ange System Manual Page 52 of 59 Hints on Installation and System Design Read only tag Tag 76LD030 read time is 117ms when the tag enters the field. The worst case is typically 150ms. To be on the save side 150ms is taken for the following calculation. 5.5 Installation Guidelines Tread = Tproc_len = 150ms. Step 6: Determine the maximum tag passing speed. v opt_proceed = Sproc_len / Tproc_len = W / Tread =
= 120mm/150ms = 120/150 m/s
= 0,8m/s = 48m/min If this doesnt meet the application requirement
(speed is too low) then the calculation with the next larger antenna / data tag pair, i.e. 77LS03 antenna and 76LD050 data tag must be repeated with step 1. In an ideal situation, the system is free from envi-
ronmental influences, proximity to metal and electrical noise. An industrial environment is nor-
mally far from being the ideal situation. For that reason the installation can only be done by a technician, who has enough know ledge about the OIS-L system. Baumer Ident offers support and training in Germany. The nearness of the antenna and/or data tag to a metal surface has more than one adverse effect on system performance. The distance between two adjacent antennae and
/ or two tags plays an important role for optimal system function. Guidelines for min. distances are given in a following section. For optimum performance please ensure that the antenna is mounted as follows:
No metal closer than 100 mm to the antenna in any direction (Hx and Hm) Data tag should be arranged as parallel as possible to the antenna surface The writing/reading range achievable depends on various factors, e.g. data tag type and position, environmental interference. For accurate values, tests should be carried out on-site. Typical values for certain antenna/tag combinations are listed in the subsequent section All values are valid for a metal free environment at an ambient temperature of 20 C. Due to compo-
nent and production tolerances as well as tem-
perature influences, a variance of 20 % is al-
lowed. A set of mounting brackets is available and can be ordered separately. When the tags are flush-mounted in iron or alu-
minium, the reading distance is substantially re-
duced due to the loss of energy through eddy cur-
rents and other losses. By applying certain application techniques, it is possible to obtain reading distances of 50% as compared to the readings in air. Page 53 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH Hints on Installation and System Design 5.5.1 Metal-free environment The closeness of the antenna and/or data tag to a metal surface has more than one adverse effect on the system performance. Installation Diagram A major effect on the system is caused when a metal surface close to the coil detunes the fre-
quency from its nominal value of 125 kHz. An iron surface will normally increase the frequency by approximately 6 kHz. An aluminium surface will increase the frequency even more; in the worst case it will cause the system to fail. A second negative influence is the loss of energy. The metal in the form of Eddy currents will absorb a certain amount of the energy transmitted from the antenna. Hence, it is important to strictly ad-
here to the mounting recommendations provided in the user manual. If mounting is required on or close to metal parts, special antennae and data tags are needed. Baumer Ident has extensive experience in this field and is therefore able to offer a solution. The following graph shows the typical drop in system performance for any combination antenna
/ data tag when the antenna is mounted in close proximity to metal (Fig. 5-5). The reduction in performance is given as the distance to metal in relation to the size of the antenna loop, expressed as percentage. Influence on system performance by nearness to metal distance antenna - Metal in % of antenna loop Example The antenna 77LS09 has an antenna loop ( D) of 340 mm. If the antenna is mounted at a dis-
tance of 170 mm to a metal surface (=50% of loop) the system performance will be reduced to 45% of the performance it has in a metal free en-
vironment. In order to reduce this great performance loss, antennae especially tuned to metall are available. This special antennae guarantee a performance of better than 90% of a standard antenna without influence of metal. Baumer Ident GmbH Read/Write Short R ange System Manual Page 54 of 59 Hints on Installation and System Design In the previous sections the various negative in-
fluences on system performance have been dis-
cussed. To recap, the main points are as follows:
Mounting of the antenna and tag close to metal is not recommended. If certain critical values are not adhered to, the system per-
formance will not only drop considerably - it can fail completely. Flush mounting of the antenna and/or tag in a metal environment requires special atten-
tion. There must be a metal free area in all directions (distance values for antennae, pls. refer to Fig. 5-5). For the tags it is normally sufficient to have a distance of 50 mm to metal in any direction. No metal brackets (or any other metal ob-
ject) should be within the active field, since this will distort the field lines and reduce system performance. 5.5.2 Mounting examples The diagrams below show a typical mounting used in industrial applications. Indicated is the recommended minimum distances between two antennae, as well as between two adjacent tags. Should it become necessary to mount the anten-
nae closer to each other than Shown in Fig. 5-6 an electronic interlock has to be arranged to pre-
vent one antenna from "damping " the other. Performance with tag and antenna close to metal Performance with metal on three sides of antenna Antenna mounted close to metal Important Note!
The more metal free area there is around the an-
tenna and tag, the betterthe system performance. Should the antenna be mounted at a distance of less than 20% of the loop diameter D, there is a risk that the system will fail. System performance with tag close to metal Generally it is less detrimental to system perform-
ance if the tag is closer to the metal than recom-
mended. Page 55 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH Hints on Installation and System Design electronic interlock has to be arranged to prevent one antenna from killing the other. 5.5.3 Distance between antennae or tags Should it become necessary to mount the anten-

The EMC guidelines are constantly being updated and more stringent demands are applied to elec-
tronic components and equipment. A considerable increase in the use of electronic equipment and appliances has taken place in re-
cent years. The required performance of the equipment increases and the physical size of the equipment decreases. The component power consumption is reduced and the communication and processing speeds increase. The more units that are in operation, the higher the risk that they will influence each other. Hence, the reason for the stricter rules that constantly challenge the electronic companies. Note! It is the responsibility of the general contractor of the total system to adhere to the EMC guidelines for the total installation. Measurements taken at the planning and in-
stallation stage will prevent expensive system changes at a later stage Specific regional or country regulations and legal requirements must not be neglected 5.6.1 General With EMC we understand the ability of electric or electronic equipment to function without any problems in an electromagnetic environment. At the same time, the equipment is not allowed to influence or interfere with other equipment in the vicinity, beyond certain limits. EMC can be separated into three general types:
Self-immunity The immunity against internal (own) electrical disturbances General immunity The immunity against foreign electromagnetic disturbances Emission The degree of radiation and interference onto other equipment. EMC tests are performed ac-
cording to all three types. All Baumer Ident equipment undergoes these rigorous tests. Since the Baumer Ident equipment is only part of a total system, it is vital for the system perform-
ance that all system components adhere to these EMC guidelines. 5.6.2 Shielding concept In the OIS-L system the data exchange between the central unit and the host is performed at a rate of at least 9600 Baud via an RS 422 interface. When Profibus DP is used, the rate is considera-
bly higher. The maximum cable length at 9600 Baud is 1000 meters. This necessitates good shielding of the data cables.

Trigger To force a continuous operation with a trigger function, a 15pole adapter must be used. This sets the dedicated trigger input to an active state. For Input 1 active Connect Pin1-Pin14 or Pin9-Pin14 and Pin6-Pin2 with a little isolated wire For Input 2 active Connect Pin1-Pin13 or Pin9-Pin13 and Pin5-Pin2 with a little isolated wire mains voltage or DC Voltage above the limit of 36VDC into it. So dont even try it!
What happens if there are spikes or drops on the power supply?
Normally nothing. The galvanically isolated DC-
DC-Converters inside can stand an input voltage between 18 and 36 VDC. Spikes from usual elec-
trostatic discharges should also do no harm onto this connector. The digital outputs are also protected against misuse. But be careful with overvoltages into the host in-
terfaces. 6.2 Miscellaneous What happens if there is a polarisation error to the power supply?
Nothing. The unit is protected against such errors. The only chance to kill the central unit is to feed Page 59 of 59 Read/Write Short R ange System Manual Baumer Ident GmbH
