Hello,
I'm trying to manage a RFID-181EIP communication module (Siemens) by a PLC-5.
To parametrize this module, It's necessary to send 2 messages. The first contain the data abd the second is an empty message (length 0) to end the parametrization.
My problem is that PLC-5 does'nt accept length 0 MSG. I tryed to change dinamically the length of MSG to 0. The CLP do it but the MSG return an error and is not sended.
Is there another way to create an empty MSG with PLC-5 ?
Thank for any help
