4 Identification Systems HG A 1 Identification Systems To ensure that the operating procedure is working properly, the data transmission between different objects (die carrier, tools, vehicles etc.) and the control system is decisive. Mobile objects have to be identified and positioned fast and safely. Thus identification systems provide a safe and economical solution, which can be installed easily. Using these systems it is possible to operate and control the process flow. Such a system is suitable for nearly all sectors in which production and transportation processes have to be automated. For the realization of these automations, data has to be recorded, collected and processed on the route of transport, at their final destination, at the premises and at the manufacturing site. 1.1 Application Examples for the Automation Automation can be realized within the following sectors: - Storage - Position fixing of vehicles and containers - Production lines - Control of material flow - Identification of containers - Control of loading and unloading processes - Positioning of vehicles in industrial engineering - Distance control of track guided vehicles - Position fixing for public transport Special advantages of the inductive identification system are a positioning accurate to a millimeter, identification within a far range and an insensitiveness to contamination. 1.2 System Components In order to create a whole positioning und identification system, transonders are needed. The antenna HG A fits the following types: Transponder HG (free codable) / HG (switch transponder) Frequency Antenna Transponder 125 khz 71451YA 71325ZA (other types on demand) 409 khz 71451ZA 71325YA, A (switch transponder) Table 1 Available antennas and transponders English, Revision 03, Date:

5 Identification Systems HG A 1.3 System Configuration Reading Station Interpreter Serial output of the read out transponder code and the positioning impulse Reading antenna Data carrier Figure 1 System configuration 1.4 Functional Description General Functional Description When the antenna crosses a transponder it supplies it with energy by an alternating electromagnetic field. As soon as there is enough energy available within the transponder, it starts to attenuate the magnetic field cyclically with its encoder. This attenuation is reflected to the antenna and generates an amplitude measurement (AM) of the transmitting component. Inside the receiver the signal will be regained from the AM, decoded and the data will be put out serially. The transponders HG can be rediscribed by the magnetic field. English, Revision 03, Date:

6 Identification Systems HG A Transmission Range and Function The field intensity of the magnetic alternating field decreases with an increasing distance between transponders and reading antenna. Thus the information exchange is only feasible within a certain area. The field length L and the field width B of the transmission range (see Figure 2 auf Seite 6) will be defined via the parallel centre line through the reading antenna (road). The distance between reading antenna and the sectional plane is indicated as S. A faultless function of the system is guaranteed if the transponders and the reading antenna move towards each other with the distance specified by S and within the range defined by L and B - provided that they are properly aligned. The transponder (line B) will even be detected in case of an offset (centre deviation). Then the positioning impulse will be output with an offset. II I Figure 2 Length and width of the interception area (view from above) Positioning is effected according to the field compensation method. The resulting field for the transponder will be deleted centrically to the reading station. At the transition to this region (registration gap or datafree range) the position of the transponder at the object will be detected exactly and indicated (see table 3 on page 7). English, Revision 03, Date:

7 Identification Systems HG A Signals and Timing With the transponders G 71310, G and G Figure 3 Signals and Timing Initially the data are insecure and the signal strength is still small (range II). Approaching further the signals of the data become stronger and can be read completely. The loss of the interception area is detected via the controller in that the thresholds are reached (3 and 4). Finally the internal interception range (range I) will be achieved. Crossing the field border at point 4 releases the center signal. Passing the next detection ranges (5 to 8) the data are read again and will be indicated. At the field border, point 8, no center signal will be released. The center signal will not even be set if the vehicle stops and drives back after having passed point 1 to 4 within the interception gap (4 and 5). The positioning signal for this transponder will only be send again if another transponder with a new code is read in the meantime or a reset is implemented by turning-off or turning- on the operating voltage. If a vehicle stops before the central pulse ends and changes the direction of travel, a wrong central pulse is generated on position 1 or 4. These positions can not be defined exactly. So the identification system should only be applied in installations without any change in direction. English, Revision 03, Date:

8 Components and Operation HG A 2 Components and Operation 2.1 Components in the Ground (Transponders) Transponders type HG (by Götting KG) are applied as reference markers within the ground. The system is compatible to all transponders of type HG 713XX used so far (depending on the installed version of the reading antenna). By using the switchable transponder HG a simple point- to- point connection in addition to the positioning is feasible. The transponder, e.g. installed within the ground, signals an approaching vehicle to the system. Thus the system is able to transfer a message to the vehicle by selecting one of 4 codes to choose from. Furthermore transponder version HG W is able to change the positioning mode. The transponder code provides 16 Bit serially or parallel. 2.2 Identifying Antenna HG A (Profibus) The antenna system is in a 53 x 31 x mm casing (polycarbonate). The antenna is connected by 5-pole cables. The terminal connector is a M12 circular connector (see Figure 4). As an accessory an elbow jack with different cable lengths is available (standard 2 m) mm M12 x 1 circular connector 5-pin (male) A-coded M12 x 1 circular connector 5-pin (female) B-coded Profibus Address Figure 4 Antenna dimensions HG A M12 x 1 circular connector 5-pin (male) B-coded Position of ferrite rod English, Revision 03, Date:

All LEDS, except for the BUS- LED, will be connected additionally for 500 ms each in order to test their function. After approximately 2 s the device is ready for operation General Information The code supplied by the transponder has a sequence of 24 bits, 16 bits are encoded. The serial interface will only be applied for the monitor programme described in section 4.2 on page 20. For this antenna the data as well as one status byte will be output via the profibus. The programming of transponders can be implemented via the profibus as well Profibus Interface By means of the GSD files HG 7145A3 GSD (section 6 on page 25) it is possible to project three different configurations.

This instruction sets the number of the last read transponder to zero. The delete statement will be initiated by a rising edge of the CLR-bit; i. e. first the status byte should be transferred with a deleted CLR-bit. The current status will be indicated in the status byte (see Table 11 on page 12). English, Revision 03, Date:

Figure 10 on page 21. The bits DATA and CD will be set after the transponder has entered the antenna field. As the reading range exceeds the programming range, the programming should be implemented not before the crossing of the antenna s centre (positioning bit is set for 100 ms), if DATA and CD are reset after the blanking interval. Programming will be initiated by a rising edge of the PROG bit; i.e. first the transponder code which has to be programmed with PROG=0 should be transferred, subsequently the same transponder code wit PROG=1. So the released programming process lasts approx. 100 ms. Afterwards the new code will be read directly and is available for the input bytes Profibus Address 2 Hex- rotary switches under 2 blind plugs are available for the adjustment of the profibus address (q. v. Figure 4 on page 8). Set the address in area 0 to 7E with a screwdriver and seal the plugs accordingly. A readjusted address will only be accepted after the antenna has been turned- off and -on again RS Interface Here the transmission parameters are fixed: 38400, 8 data bit, even parity, continuous output, ASCII- coded. Transponders can be programmed via the serial interface (see section 4.2 on page 20).

14 Components and Operation HG A The data is put out ASCII coded, the single sets are seperated by a comma. Data lines are ended by <CR LF>. Data of this format can be recorded with Hyperterm and be saved as a so called CSV file. Those data files can be easiliy modified with calculation programms like Excel. By entering the monitor programm is started PosiPuls The postitiong impluse is triggered as soon as the middle is crossed. His duration is 100 ms. With triggering this impluse 24 V are switched to the corresponding output with a current limiting of 20mA. NOTE! Refer to chapter Signals and Timing on page 7for the timing of the PosiPuls.

15 Mounting and Setup HG A 3 Mounting and Setup 3.1 Testing a Transponder It is possible to test the transponders with a reading antenna and a connected PC (q. v. section 4.2 on page 20). 3.2 Mounting Transponder Range and Positioning accuracy will be influenced by - Metal parts lying on the ground (sheet metals) - Reinforcement laid close to the transponder - Induction loops, e.g. formed by structural steel NOTE! Individual metal rods have only little influence and may hurt the metalfree area partially (see figure Figure 5 on page 16). There is no influence on the positioning accuracy caused by - Environmental influences as snow, ice and water - Contaminations as oil, tar etc. Basically the following Mounting Instructions for Transponder G have to be observed - Keep a minimum distance of 500 mm between the transponders. - Keep a minimum distance to the metal parts (see figure Figure 5 on page 16). The interference on positioning accuracy and range depends on the size and the range of the metal parts. - The minimum distance between conductors with a diameter smaller than 6 mm has to be 2 mm. Which end of the transponder is turned upwards is insignificant for the range or the function Mounting in very solid Ground (e. g. concrete) - No additional protective casing necessary. - Vertical alignment required (otherwise a position error will be generated). - Transponder should be sealed (e.g. with a two component epoxy resin). - To protect the transponder use either a covering cap or apply an epoxy resin layer (thickness approximately 1 cm). The drill hole should be wide enough so that the cover cannot put pressure on the transponder. English, Revision 03, Date:

16 Mounting and Setup HG A Mounting in Tough Material (e. g. tar) - Protection tube necessary (e. g. of fiber-reinforced plastic material). Choose the diameter of the load accordingly. - Arrange the transponders unmounted or vertical in foamed material (otherwise a position error will occur). - To protect the transponder use either a covering cap or apply an epoxy resin layer (thickness approximately 1 cm). The drill hole mouth should be wide enough so that the cover cannot press on the transponder. e. g. air cushion foil or plastics spring metallfreier Raum Figure 5 Metal-free area around the transponder HG Reading Antenna Mounting Drills G A Figure 6 Mounting of the identifying antenna: Position and size of the drilling To achieve a maximum range (> 50 mm) of the reading distance, it is recommendable to mount a 10 mm plastic plate or a 10 mm spacing bolt between the steel or aluminium rack and the reading antenna. When using spacing bolts a large washer is to be placed under the reading antenna. English, Revision 03, Date:

17 Mounting and Setup HG A NOTE! If several antennas are applied within one installation they have to be mounted in a minimum distance of 1500 mm to one another to guarantee a smooth production flow. All indications refer to the position of the ferrite rod in the antenna: Direction of Travel metal-free area metal-free area mounting level mounting level reading distance Position of the ferrite rod Figure 7 Nominal reading distance / position of the antenna ferrite rod Connection Connection cables are not part of the scope of supply. The needed kind of cables are commercially obtainable at many manufacturers (e. g. Binder M12 line 2 m PUR 5 x 025). Accessory parts as an elbow jack with different cable lengths available (standard 2 m). If a high interference level is expected shielded wires ought to be used. 3.4 Maintenance The system is largely maintenance- free. Generally maintenance is restricted to - Visual examination of the antenna - Inspection if all screws, cables and plugs are properly fixed. English, Revision 03, Date:

18 Software HG A 4 Software Transponder Programming and Update of the Internal Software For the realization of these requirements the antenna has to be set to the monitor mode, i. e. connect the serial interface of a PC / laptop with the appropriate pins (Rx and Tx) of the antenna. Then start the terminal program (see below). The interface parameters have to correspond to those parameters adjusted by DIP-switches of the reading device. 4.1 Terminal program In the following we refer to the program HyperTerminal (Hypertrm.exe) which is part of the scope of supply of Microsoft Windows 95/98/NT.
