Hi all.
I have Powerflex 4m, i read a manual and find out that it support Modbus RTU via RS485. I try to communicate with it, but I have no answer from it. I looked at d015 parametr and find out that it recive my data, but it doesn't answer anything. From the PC side i'm using Linux and libmodbus-2.0.3. I think wiring is correct, becouse it recive my data. I've checked every parametrs according to ProwerFlex manual.
Please, help what else can be? I need to do it very quickly, but i have never do it before.
Thank you in advance.
