Hi,

I have a Premium PLC and I need to communicate over ethernet to a WEG VSD with a Anybus S Ethernet/IP card installed.

Any suggestions on the way forward please as I can hardly find any info on this?

Is it possible to use Modbus TCP/IP with this card?

Thanks!

 

While your PLC knows all about Modbus/TCP, I think your drive does not. The effort must be for your PLC to form command strings of characters that are understood by the VFD. The VFD knows several sets of interfaces, but it looks like your hardware limits it to EtherNet/IP, a Rockwell supported protocol. You need to call WEG and ask them for guidance.
