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 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 SQLBridge 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.
