Local Area Network. Refers to internal networks contained within an enterprise as opposed to WAN (Wide Area Network) which joins LANs into "super" LANs (such as combining three different locations each with their own LAN). This is often referred to as Intranet (not Internet). Intranet can include many LANs connected into a WAN for a single company.


We often talk about layers in Ignition in reference to the software stack. Each layer is a piece that works because of the layers below it. For example, the Platform layer of Ignition requires the VM (Java) layer below it to function, and is required by the Module layer above it.


In Ignition we refer to libraries in several places, but it just means a collection of similar items. These could be a collection of images, scripting functions, components, or more.


A 6 digit key that (when loaded) contains information about the Ignition Gateway and it's modules. You can run an unlicensed Ignition in Trial mode, or you can load a license and have unlimited access to the modules. You can also install modules that are not on the key, and they will run in trial mode.


We pride Ignition on being unlimited, but sometimes you want a smaller system at a lower cost. The "limited version" of Ignition refers to using a special license that applies restrictions to some or all of the Ignition modules. See the modules section for more information, and ask your sales representative for information about pricing.


The Localization feature allows for the translation of text into multiple languages for display on client screens. It allows users located in different countries to set their default language so client screens can be displayed in their native language.


The Logix family of devices are PLCs created by Allen-Bradley. They include MicroLogix, CompactLogix, and ControlLogix devices. These devices allow for varying amounts of tags and throughput to fit many systems' needs.



Lightweight Directory Access Protocol (LDAP) is a software protocol used to access and manage user directory information. In Ignition, the Active Directory Authentication profile uses LDAP to filter which users are allowed access. Active Directory then returns user information (such as name, contact, roles, and security) that makes up the Authentication profile.
