Step 1. Installing Ignition Gateway

...

Ignition Gateway is the SCADA host platform, which performs all the traditional SCADA functions as well as allowing other MQTT Modules, such as the MQTT Server and Cloud Injector modules, to be loaded.

Quick Start Guide

Step 2. Installing MQTT Server

Every MQTT solutions needs at least one MQTT Server for the MQTT Clients to connect to.  There can be Edge Clients, which are typically data producers, and Host Clients, which are typically data consumers. However, they are both considered clients that connect to the MQTT Server.  There are three options for the server depending on the size of the system:

  • MQTT Distributor– Supports up to 50 client connections and installs as a module on the Ignition Gateway.
  • MQTT Distributor Plus- Supports up to 250 client connections and installs as a module on the Ignition Gateway.
  • Chariot- Supports unlimited client connections and installs as a standalone application on a Linux server or VM.

Click here to download the MQTT Distributor module – *note* scroll almost to the bottom of the page  select “Strategic Partner Modules” for the Cirrus Link Modules.

...

MQTT Engine is a host client that allows Ignition to connect to MQTT Servers and receive MQTT messages.  MQTT Engine supports Sparkplug B which enables the auto-discovery of devices and tags with the rich tag metadata.

Click here to download the MQTT Engine module - *note* scroll almost to the bottom of the page  select “Strategic Partner Modules” for the Cirrus Link Modules.

Ignition Edge is a condensed version of the Ignition Gateway. Ignition Edge has the same familiar UI and comes pre-configured with MQTT Transmission module, which is an MQTT Client that takes Ignition tags and transmits them to the MQTT Server. Ignition Edge solutions come with unlimited tags and are equipped with OPC UA along with Modbus, TCP, and Siemens drivers, and the Allen-Bradley suite of drivers. Other drivers supported by Ignition, such as DNP3 and Modbus RTU, can be added onto Ignition Edge solutions for an additional cost.
