RSLogix 5000 Task Function

In RSLogix 5000 there are three main types of tasks:

• Continuous: It continuously occurs
• Event: It occurs only after certain events occur first
• Periodic: It occurs periodically

Every task must have a main routine. Every routine can have a sub-routine and/or fault-routine.

In RSLogix 5000, you can run up to 32 tasks with 0 to 15 priorities. That means if all the possible tasks are used some have to have the same priority.

In RSLogix 5000 versions 13 or lower 32 programs can be run within a single task. In RSLogix 5000 version 14 or higher (currently at 17) up to 100 programs can be run within a single task.
