CMT-G01 With OPC UA Server And Modbus Gateway
cMT-G01 with OPC UA Server and Modbus GatewayWeintek USA, Inc.www.WeintekUSA.com(425) 488-1100Rev. Oct 31 2018cMT-G01 with OPC UA Server and Modbus GatewayIntroduction:Industrial IT Technology has quickly advanced with the integration of plantfloor data, supervisory control demand, ERP, and even new cloud-basedapplications. Integrating legacy and different brands of factory machines hasnever been an easy task since the controllers in a factory use differentcommunication protocols. To facilitate integration of numerous proprietaryprotocols, Weintek has developed the first Gateway protocol converter: cMTG01. The cMT-G01 gateway provides the necessary IIoT connectivity toretrofit existing machines into a single protocol.This document discusses how to utilize the cMT-G01 to build an OPC UAserver, which is a standard protocol for IIoT systems, and allows OPC UAclient to access data.Benefits of cMT-G01 Supports OPC UA for Integration of SCADA or ERP systems Supports MQTT and has built-in broker for publish-subscribemessaging protocol Connectivity to AWS, Azure, and IBM IoT platforms via MQTT Supports MQTT Sparkplug B specification Supports Modbus gateway Supports Protocol conversion Additional Data logger and event detector SQL synchronization capability to MySQL and MS SQL database serverfor data log and event log EasyAccess2.0(Optional)– Remote access factory equipmentPage 1 of 15
cMT-G01 with OPC UA Server and Modbus GatewayEquipment & software:1.2.3.4.HMIArduino boardiR-ETN remote IOcMT-G01Note: In this demonstration, Easybuilder pro version 6.01.02 is used.Wiring diagram:Before configurationThe HMI communicates with the Arduino board via Modbus RTU protocol.The HMI communicates with the iR-ETN remote IO via Modbus TCP protocol.After configurationIn this way, the HMI program is changed because the HMI uses Modbus TCPMaster protocol to query the cMT-G01. The cMT-G01 acts as a ModbusTCPto-ModbusRTU bridge, which is a Modbus gateway. It saves the cost ofpurchasing an extra communication module of the PLC.Page 2 of 15
