gloTermCirrus Link MQTT Distributor Module
termSynsDistributor Module

This is an Ignition module made by Cirrus Link. It acts as a hub (Server) for MQTT clients (systems or devices) to securely connect, publish, and subscribe to data. It supports up to 50 Edge of Network Gateways (each can support multiple PLCs).

Glossary term
gloTermCirrus Link MQTT Engine Module
termSynsEngine Module

This is an Ignition module made by Cirrus Link. It allows Ignition to be a Client and connect to any existing MQTT Servers. These servers do not need to be using the Distributor Module, and are commonly stored in the cloud. This modules gives Ignition access to any devices connected to the MQTT Server, which is potentially thousands of devices through Edge of Network Gateways.

Glossary term
gloTermCirrus Link MQTT Injector Module
termSynsInjector Module

This is an Ignition module made by Cirrus Link. It emulates Edge of Network Gateways, simulating live PLC data. It is configurable using CSV filesm and can simulate multiple Edge of Network Gateways concurrently. This module is used for testing the functionality and throughput of different IIoT solutions using MQTT and Ignition.

gloTermControl System

1- A control system is a device, or set of devices, that manages, commands, directs or regulates the behavior of other devices or systems. Industrial control systems are used in industrial production for controlling equipment or machines. -Wikipedia

2- Refers to a PLC, Process control system, all field sensing devices, motor and valve control devices, the wiring to the controller, the controller itself, software and anything else related to controlling a manufacturing process. Some antiquated control systems use straight electrical wiring or pneumatic control systems without the use of computers. The majority of control systems are computer-based though.
