In the Studio 5000 software ladder logic program, how is an instruction indicated when it is on display?

In the context of the Studio 5000 software for programming Allen-Bradley PLCs, specific visual cues are provided to help users identify the status and function of instructions within a ladder logic program. When an instruction is displayed in the software, it highlights in green. This green highlight indicates that the instruction is active and can be executed as part of the program's logic.

This feature aids users in quickly assessing which instructions are part of the executing logic, thus enhancing the effectiveness of program development and debugging. The other visual indicators in the software serve different purposes, such as indicating errors, warnings, or other statuses, but the green highlight specifically denotes active instructions in the ladder logic program.
