Maple Systems cMT-G01 & cMT-G02 Communication Gateways

In this article we are connecting a Maple Systems cMT-G01 / cMT-G02 Communication Gateway to the Nimbus808 solution platform using MQTT.

Requirements:

  • Nimbus808 Account
  • cMT-G01 or cMT-G02 Unit
  • EBPro

EBPro Project Creation

  1. Download and Install EBPro
    • Download and install EBPro v6.10.01 or greater. Contents of this guide may not be applicable to earlier versions.
    • Launch EBPro once installed
  2. Select the appropriate HMI model

Configuring MQTT Object

  1. Configure the cMT-G01 / cMT-G02 Communication Gateway to send data to Nimbus808
  • Head to the IIoT/Energy tab and then click MQTT
mqtt_btn
  • Check the Enable checkbox then Settings… button
mqtt_enable
  • Go to General tab on the dialog menu that will be displayed.
  • Edit the Settings as follows:
    • Cloud Service: Generic

    • Check “Use Domain Name”
    • Set the Domain name of your Nimbus808 instance
    • Configure the remaining settings according to your requirements
mqtt_connectionInfo
  1. Configure the MQTT to send data to Nimbus808
  • Click the “New…” button as shown below to create the topic to publish information
