E2C comprises 3 layers of software that run on a Robustel Gateway.
The diagram below highlights the fundamental structure of E2C with the “Southbound” app responsible for interfacing with industrial protocols/sensors over RS232, RS485, Bluetooth, Ethernet, etc., and the “Northbound” app responsible for transmitting data to Cloud services/Protocols as required by the customer application.
In between Northbound and Southbound app is the “Broker” which decouples the two interfaces and provides a generalized “any to any” transmission path for disparate types of data and destinations. The Broker in this instance should not be confused with a typical MQTT Broker used elsewhere in the solution architecture.
