PLC5 and RIO

[ingjaop]

I have a PLC5/40 and I communicate with a remote RACK by using RIO channel A. I use the BTW instruction but gives me error. How do I implement the instruction with another that does the same?.

If you are asking how to use one of the other channels for the RIO you have to configure the channel under the comm settings in the processor tree. The channel has to be set as RIO, the baud rate, and the rack configurations. If the processor has a later firmware you can scan the rack / racks in program mode and they will be added automatically. If your rack address's changed you will need to edit your block transfers - i/0 also.
