A MICRO-CONTROLLER BASED PROTOCOL CONVERTER FOR INTERFACING ELECTRONIC CONTROLLERS OF ELECTROSTATIC PRECIPITATOR AND DISTRIBUTED CONTROL SYSTEMS

摘要

This invention relates to an embedded protocol converter for converting specific or dedicated protocol to general purpose MODBUS protocol the protocol converter providing communication interface between a plurality of field level controllers (20-25) and a plant level controller (26) of an electrostatic precipitator, the field level controllers having different communication protocol, the protocol converter comprising a microprocessor (01) enabled for +/10mA current loop communication, RS485 communication and CAN bus communication, the hardware being supported by software structure stored in a flash memory of the microcontroller (01).
