IIoT Architecture

Overview

Ignition can collect data from any devices at the edge of the network, publish that data to a central broker, and push that data to subscribed industrial and line-of-business applications. Ignition IIoT can connect to PLCs in the field through the use of the MQTT Transmission module, field devices with Ignition Edge MQTT installed, and/or MQTT-enabled edge gateways and field devices that use the Cirrus Link Sparkplug MQTT specification. This data is published to an MQTT broker, this broker can be located on-premise, in the cloud, or a hybrid of the two. The MQTT Engine module located on an Ignition Gateway can subscribe to any data published from the broker. This data can be used in any Ignition application.

IIoT Architecture Example

IIoT architecture typically involves the use of the MQTT protocol to communicate with a large number of devices. MQTT is a lightweight and secure protocol that makes use of a unique publish/subscribe transportation method. Additional information on the MQTT protocol and modules can be found in the Cirrus Link documentation.

The Standard Architecture can easily be expanded with the MQTT modules to collect data from numerous Edge of Network devices. Data collected by the MQTT Engine can be historized and presented in a client with the Vision module, or via reports with the Reporting module.
