V680S RFID WITH ETN-21

[HP08988 0]

Hello,

Is it possible to configure 18 RFID on single ETN21 card. ? I am using the CJ1W-CPU35 PLC.

As per the current FB I have, its been integrated with 2 IR registers. Which mean I can not use more than 8 RFID readers on single CPU. is this correct configuration?

Thanks

Yes, it is possible.  You will have to write code to communicate with them in a sequence or on demand as you cannot communicate with all of them at the same time.
