MODBUS Communication Protocol

Modbus is a kind of serial asynchronous communication protocol with RS485 as the physical interface. Being designed for Modicon PLC, it has the structural features of PLC. In network control, it can read and write the PRS 3000 as if it were a PLC. It can project the start and stop control, status information (current, fault etc.) and function parameters to the holding register (4:XXX). Its read and write control shall be conducted through the PL master station. When connected to other Modbus equipment, connection should be conducted as per the diagram below:
