Hi everybody,
I found this post searching for info about a similar problem I'm trying to solve.
I've been told than it's possible to communicate a CJ2M-CPU33 with this device through Modbus RTU using the built-in serial port of the PLC with a CP1W-CIF11 interface for RS422/485.
I only need to read some registers from the device to save them in the PLC memory, so it would be nice to avoid the expense of a SCU.
Do you know if this possible? Is there an existing FB useful for this?
Thank you very much for your help.
