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.

termLabelsgloTermControl 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.

Glossary term

A software program that is used to contact and obtain data from a Server software program either on the same computer or on another computer. A client makes a request and the server fulfills the request. In Ignition, a client is the runtime that operators use to interact with projects, and is launched from the Ignition Gateway webpage.

Glossary term
termLabelsgloTermControl System Specialist

Refers to a person with highly specialized knowledge of control systems. Such a person must have a working understanding of computers, computer programming, IT and networking, electrical systems, hydraulics, pneumatics, mechanical systems and often chemistry. Such a person may be degreed or not. When degreed they are usually electrical or mechanical engineers.

Glossary term

An Allen-Bradley (Rockwell) family of PLC controllers, a very powerful, networked, and broad family.

Glossary term

Open network protocol which operates at a higher speed than DeviceNet but lower speed than Ethernet.

Glossary term

Refers to the field of Automated Control Systems that control manufacturing machineries. These are usually highly computerized using specialized controllers. Controls is a specialized field which is invisible to the public at large but which is huge because it is involved with nearly every manufacturing process on the planet.


Glossary term

Central Processing Unit (CPU) is the main processing chip of a computer. The part of the computer or computer system which performs core processing functions.

Glossary term

Cron (or Crontab) is popular scheduling format that allows users a simple way to set repeating scheduled events using only 5 values. This is used in Ignition's Report module to schedule report generation, as well as in Gateway auto-backups. You can learn more about it here on wikipedia.
