MODBUS Protocol for Reading Parameter of AC Drive

Abstract

This research paper is aimed for reading the parameters of AC Drive by using MODBUS Protocol. This communication protocol is used for Programmable Logic Controller (PLC) and this PLC is handling by controller. Hence in this we have checked and observed the parameters of AC Drive by PIC controller with Docklight Software. Here, Docklight software works exactly as AC Drive to read parameters by MODBUS Protocol. MODBUS module is a TTL to RS485 converter Module.
