Hello,
I'm using modbus rs485 with LS/LG PLC G7MU to control several inverters ATV31 Schneider. I can start, stop, send speed ref, receive feedback etc, one by one.
The problem is I can't start all inverters in the same time, together. If I send start signal on the same time for all inverters, communication become error. Then I put some delay, after send start to inverter-1, delay 10sec, then start inverter-2...............
The condition is same to receive feedback signal from inverter, must one by one.
Each inverter has its own ID.
Please help if any information, how to start all inverters together on same time.
Thank you
