9.2 Operating mode 2 - Reading Triggered by the PLC

The PLC sends the command "GT" to trigger a reading process. After finishing the reading process the

transponder code or an error code can be read by the PLC.

9.2.1 Principle of Reading a Transponder in mode 2

• Trigger the Reader device using the command "GT "(and <CR> in addition)

• Wait for answer of the reader device, polling status bit in response telegram (see manual [2] : Pro-

fibus-DP Communication)

• Request answer (see manual [2] : Profibus-DP Communication)

10 Warning Notes

• This reader is an active electrical transmission system and radiates in the frequency range of ap-

proximately 124 kHz. When connecting a defect or a not suited reader to the device the radiated

power can be higher than 42dBµA/m (measured at 10 m distance). The operator is responsible

that people at risk are not endangered by the device..

• Do not operate the device with open housing, as otherwise there is a danger, that positions with

dangerous voltage can be touched.

• Never operate the device with defect antenna cables. The antenna cables may conduct dangerous

voltages. When disconnecting an antenna cable please assure that the device is turned off and the

cable was grounded for a short time before touching it. Otherwise stored energy of the antenna

may cause harm.

• The reader box has to opened by well educated people only.
