CP1L-E Mbus RTU with MX2, JX, RX and Yaskawa Inverters

[Arpad Nagy]

Hi All,

Unfortunately due to the current situation, we cannot build a homogeneous system
So we need to control several MX2, JX, RX and Yaskawa Inverter (~20pcs) with same CP1L-E  PLC if possible.

I can control them separately:
- Omron Inverters with function block INV002_Refresh_X31
- Yaskawa inverter with "traditional" modbus commands (D32300 and 640.00)

How do I control MX2 without a function block? I can write frequency and read parameters, but can't start/stop it.

I couldn't find a universal function block or other solution which I could use for all of them.

I want advice, is it possible control all with CP1L-E?
If so, by what a method?

I really appreciate any help you can provide!
