Abstract
Introduced the method to realize the communication between programmable controller and power station controller based on Modbus RTU protocol with RS-485 serial port.Modbus protocol is a kind of common protocol applied to electron controls,it is usually used to realize communication with distributed I/O (remoteness I/O),which has become a kind of national standardization at net protocol criterion of industrial automatization.
A significance statement is not available in the OpenAlex record.
