Tags in Ignition are points of data, and can have static or dynamic values that come from an OPC address, an expression, or a SQL query. They also offer scaling, alarming, and meta information facilities. The different types of tags include: OPC tags, Memory Tag, Expression Tag, SQL Query Tags, and Complex Tags.

Tags in a PLC are very similar but lack many of the meta properties that Ignition tags have. Usually, these PLC tags only have a value, timestamp, and the OPC Server will sometimes add a quality property to them.


TEEP stands for Total Effective Equipment Performance

Overall Equipment Effectiveness (OEE) quantifies how well a manufacturing unit performs relative to its designed capacity, during the periods when it is scheduled to run. Total Effective Equipment Performance measures OEE against calendar hours, i.e.: 24 hours per day, 365 days per year. This is useful for companies that want a metric for how effective their scheduling is.


A template is an object that you can use to create many identical copies. In Ignition, a Template is referring to the Vision module's Template feature that allows you to link many components together as a definition and create instances across your projects. Updating the master will update all instances.

There are Tag templates too, but these are called User Defined Types (UDTs).


Third party software only makes sense in relation to other software. It almost always means that there is an additional piece of software that works with or inside of another piece of software, but it was created by a company other than the one that made the main software. With Ignition, there have other companies that make modules, and both the company and the module is considered 'third-party.'


This is the most common way to show data in a chart. Data points are plotted against time.


A computer monitor that can be operated by touch (like a smartphone or tablet) instead of requiring a mouse. Usually referred to as a touchscreen terminal that often has a full computer included in it, making it a standalone option that can be mounted in a control panel. Ignition has a built-in Touchscreen Mode that takes advantage of these devices by showing a keyboard when needed.


The SQL Bridge module uses Transaction Groups to transfer data between OPC devices like PLCs and databases. They perform a variety of actions, such as storing data historically, synchronizing database values to OPC, or loading recipe values. A variety of group types, item types, and options means that Transaction Groups can be configured to accomplish almost any task. There are four types of groups: Historical, Standard, Block, and Stored Procedure.


The Translation Manager is where new terms and phrases are added to the translation database. The translation database can be viewed and edited in the Translation Manager located in the Designer.


Trending or Trending screens are displays that show historical data. Usually shown as charts on a window, these displays will track changes over time so you can see rising or falling levels and predict what your process is doing.


A trigger is an event or value used to initiate some action. Often we talk about PLC tags being triggers for a Transaction Group to run. IE when a tag value changes to True, the Transaction Group will start entering records in the database. You might also hear about a "triggered execution." This is just a fancy way of saying that a trigger caused something to start running.

Also, a trigger can refer to triggering an Event Script to happen. This just means that the corresponding event happened and caused the code to start running.

The TCP (Transmission Control Protocol) standard defines how to establish and maintain a network conversation through which applications can exchange data. TCP works with the Internet Protocol (IP), which defines how computers send packets of data to each other. The entire IP suite used to interconnect network devices on the Internet is commonly referred to as TCP/IP.

In mathematics, a tuple is a finite ordered list (sequence) of elements. In Python, a tuple is a sequence of immutable Python objects. Tuples are sequences similar to lists. Tuples use parentheses, cannot be changed (immutable), and can hold mixed data types. Lists use square brackets. Creating a tuple is as simple as making a list of comma-separated values.
