knt2009 Posted February 16, 2015 Report Share Posted February 16, 2015 Dear all, I am new on this forum, even though I an using the Unitronics PLC for more than 10 years now. I have a problem with the RS485 MODBUS communication to the frequency converter. After I have established the communication to the converter I am not able to connect to the PLC with the programing computer. I have tried all possible settings of the comunication protocol bur without sucess. Can somebody give me some advice what to do? Is there a possiblity to do somehow a reset of the PLC? I am using M91 2 R2C Thanks and best regards, Quote Link to comment Share on other sites More sharing options...
