Modbus LinPAC




	Introduction Modbus is a communication protocol developed by MODICON Inc. in 1979. It's a standard, truly open and the most widely used network communication protocol in industrial automation field. Besides, Modbus is very wide known protocol in the industrial manufacturing and environment monitoring fields, and suit master-slave or query-response distributed I/O applications.



	LinCon/LinPAC can use Modbus/TCP and Modbus/RTU protocol to communicate with I/O modules in the unit via the RS-232/485 or Ethernet interface, and support Modbus/RTU to Modbus/TCP converter. LinCon/LinPAC's COM port can be setted as gateway mode, and connect to Modbus/RTU device. Host PC can link the Modbus/RTU device by Modbus/TCP protocol with Ethernet.



	LinCon/LinPAC provide Modbus SDK by C language. User can use it to integrate several serial devices. Thus the controller can be a Modbus/TCP slave and Modbus/RTU master. The Modbus SDK not only communicate with Modbus/RTU device but also register based programming method (easy to use).
