Custom Communication Protocol for Intelligent LCD Display Module HMI
1. HMI and Communication Protocol
With the development of industrial technology, the application field of HMI (Human-Machine Interface) is becoming increasingly broad. The custom communication protocol implemented by Topway's intelligent LCD display module can maintain the confidentiality of enterprise data to a certain extent, enhance the diversity of product functions, and solve the problem of incompatible communication protocols.
The serial communication rules for HMI, except for standard Modbus protocol products, are mostly based on the protocol rules set by the original manufacturer.
