QEdgeGateway - PUBSUB Device
A hardware device that Publishes and Subscribes data from an industrial environment such as a PLC, an analyzer, or a smart sensor….to a data center.
From Modbus/TCP, Ethernet/IP, ProfiNet, or Modbus/RTU, the industrial data gets served up or published via MQTT to a Broker that resides on our set of servers (AWS) at a Data Center. Preset changes or on/off commands can be sent from the data center back to the QEdgeGateway via the Broker…i.e Subscribing data back to the Gateway and to your PLC. The IIoT community refers to this as PUB SUB.
