As examples, here is a sample application connecting a RF300R with a SiemensET 200S distributed IO station,along witha manual for the unit: How can you operate an RFID Reader on an ET 200S? SIMATIC Sensors RFID systems SIMATIC RF300 Hope this helps, Daniel Chartier

I can see some hex values receving from reader on RS232 interface, like 02 18 00 18 00 00 00 00 00. Dont know which command should i send to get response from reader. Thanks Puneet

There is also an example for S7-200 PLC.
