Hello, friends. I have a Micrologix 1100 connected to a Schneider ATV312 drive through Modbus RTU. My intention is to control the frequency of the motor through the modbus conection, and start it using the drive built-in keypad.
I configured all the parameters in order to do this and I made it, I controled the frequency of the drive and can start de motor through the keypad, but despite I made this, the error flag of my MSG instructiong gets triggered with time out error.
I made just a simple ladder logic that send frequency value to the modbus register using a bit, and reset my instruction after a determined time if an error is detected. But do not understand why the error flag of MSG gets triggered if communication has been done (I can see the frequency value in drive built-in screen).
