Communication System between Touch-Screen and Counter Based on MODBUS Protocol
We introduce the communication system between WeinView touch-screen and counter,analyse MODBUS protocol,study the asynchronous serial communication between touch-screen and counter based on MODBUS protocol.We use the touch-screen as PC and the counter as next crew and use MODBUS RTU protocol data transmission format in communication system.The communication between touch-screen and one or multiple counters is achieved and a distributed control system is formed.
