    CT100 inverter Communication protocol 9 Communication protocol The CT100 series inverters provide RS485 communication interface. You can realize centralized control via PC/PLC (set the run commands and function parameters of the inverter, read the work state and fault information of the inverter) to meet the specific requirements.
  • Page 156 5. Communication data format The Modbus protocol communication data format of CT100 series inverters is as follows: In RTU mode, the minimum interval time should be at least 3.5 bytes for message transmission, which is the easiest way to achieve a variety of character time at the baud rate.
