i have a trouble in establishing communication with Yaskawa v7 AC drive to ABB 07KT51 plc through RS485 Modbus Protocol. I have selected proper settings of baudrate-19200, stop bit-1, parity-none, etc., and i have checked the plc port by modsim32 software it is working ok. but i am not able to communicate to the drive. once i tried with checking the port of drive through modscan32 software but was not successful.
