Introduction

The MGate 5105-MB-EIP is an industrial Ethernet gateway for Modbus RTU/ASCII/TCP and EtherNet/IP network communications with IIoT applications, based on MQTT or third-party cloud services, such as Azure and Alibaba Cloud. To integrate existing Modbus devices onto an EtherNet/IP network, use the MGate 5105-MB-EIP as a Modbus master or slave to collect data and exchange data with EtherNet/IP devices. The latest exchange data will be stored in the gateway as well. The gateway converts stored Modbus data into EtherNet/IP packets so the EtherNet/IP scanner can control or monitor Modbus devices. The MQTT standard with supported cloud solutions on the MGate 5105-MB-EIP leverages advanced security, configuration, and diagnostics to troubleshoot technologies to deliver scalable and extensible solutions that are suitable for remote monitoring applications such as energy management and assets management.
