Cirrus Link MQTT Distributor Module

Created Dec 30, 2020 (11:58) by Unknown User (Anonymous User) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

Synonym(s):
  • Distributor 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).

Cirrus Link MQTT Engine Module

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

Synonym(s):
  • Engine 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.

Cirrus Link MQTT Injector Module

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

Synonym(s):
  • Injector 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.

Control System

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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.

Client

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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.

Control System Specialist

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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.

ControlLogix

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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

ControlNet

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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

Controls

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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.

 

CPU

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

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.

Cron

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

Synonym(s):
  • Crontab

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.

Examples
30 1 * * * # Every day at 1:30 AM
0 0 * * 0  # Every Sunday at midnight

CSV

Created May 11, 2016 (22:38) , last modified Jul 25, 2021 (12:22) by Unknown User (null)

A Comma Separated Value (CSV) file is a way to store tabular data in a text file. It uses commas to separate columns of data, and newlines to separate rows. It may have zero or more header rows with column names or other data.

Example
"column a","column b","columnc"
1,2.3,"abc"
4,5.22,"def"
