And a ModbusRTU protocol command (Modbus is a serial communication protocol, and ModbusRTU protocol is a Modbus protocol suitable for a serial communication control network), a ModbusTCP protocol command (ModbusTCP protocol is a Modbus protocol suitable for a control network based on ethernet TCP/IP communication), and a Canopen protocol command (a high-level communication protocol built on a control local area network) are encapsulated in the industrial personal computer 100, so as to implement communication between the industrial personal computer 100 and the PLC system 200.
