Interactive pdf version of this information MQTT IIOT Recipe - Ignition 8

The Ignition based MQTT Architecture steps through the process of how to install and set up an end to end solution in order to gather data and send to the cloud. This architecture provides a superior OT solution using the Ignition platform by Inductive Automation.

The minimum requirements for this end to end solution are:

1. Ignition Gateway platform
2. MQTT Server - either MQTT Distributor running as a module on the Ignition Gateway or standalone Chariot Server
3. Host Client - MQTT Engine running as a module on the Ignition Gateway
4. Edge hardware - select appropriate edge hardware platform
5. Edge Client - Ignition Edge IIoT
6. Protocols - gather OT data from existing field equipment RTU's / PLC's using native protocols
7. Cloud Injectors - to transmit OT data to the cloud for big data analytics


Step 1. Installing Ignition Gateway

The unlimited platform for SCADA and so much more.

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.

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.

Step 3. Installing MQTT Engine

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. With the correct configuration MQTT engine can also parse non Sparkplug B messages.

Step 4. Selecting Edge Hardware

Ignition Edge runs on most Edge Hardware platforms that support Java and have at least 1GB of free memory, this includes most Embedded edge hardware platforms or even a Raspberry Pi.

Step 5. Installing Ignition Edge Client

Ignition Edge is a condensed version of the Ignition Gateway. Ignition Edge has the same familiar UI and can be 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.

Step 6. Installing Industrial Protocols

To connect to your device, go to the Configure section of the Gateway webpage and scroll down to OPC-UA Server > Devices.  The Device page will appear showing all your installed devices.  To add a new device, click on the on the blue link, Create new Device.  Scroll through the list of devices, and click the radio button next to the type of device connection that you are interested in:

Step 7. Installing Cloud Injector Modules

The Cloud Injector Modules install on the primary Ignition Gateway and allow specified Ignition tags to be sent to the cloud with a Cloud Injector originated connection. Thus, no inbound ports are open on the Ignition Gateway server for this cloud connection.  Data is sent using the same efficient report by exception methodology to reduce data bandwidth and cloud injection costs.

All major cloud providers are supported:
