Controller scoped tags consist of data that can only be accessed by the routine within a single program.

Controller Scoped Tags

In programmable logic controllers (PLCs), these are tags or variables that are accessible within the entire controller program, rather than being limited to specific subroutines or tasks.

Data

Information processed or stored by a computer or device, essential for tasks such as analysis, decision making, and control in automation systems.

Routine

A sequence of instructions or operations performed repeatedly in a control system or software to accomplish a specific task.
