Omron CP1L Modbus RTU to VFD

Hi all,

I've got a small project requiring me to communicate to an Eaton DE-1 Inverter from an Omron CP1L PLC via a CP1W-CIF11 Comms board.

I cannot find anywhere the correct structure for the program. Is there a function block that would suit this task, or does anyone have any example programs they wouldn't mind sharing please?

I've achieved this before with an S7-1200, without a great deal of difficulty, however I'm not as confident with CX programmer these days...

I need to control 20 drives, simple start, stop and speed reference with fault word as well, ideally. Nothing too complex.

Thanks in advance guys.
