Multitasking Blocks

Multitasking blocks control the starting and stopping of multiple
independent tasks (multitasking) in the motion controller. The motion
controllers allow execution of up to ten separate tasks simultaneously.

The following table presents the icons for each block in this category
along with a brief description. More detailed descriptions of the blocks
are contained on the pages following this table.

Use this block:

To:

• Turn on multitasking and begin executing a new task (Start New

Task Type)

• Stop execution of the current task (Stop Current Task Type)
• Stop execution of a selected task, other than the current task

(Stop Other Task Type)

• Resume execution of a previously stopped task (Resume Task

Type)

• Turn off multitasking by disabling the task dispatcher (Stop

Dispatcher Type)

• Turn on multitasking by re-enabling the previously disabled task

dispatcher (Restart Dispatcher Type)

• Check the task dispatcher to determine whether or not a selected

task is running

• Pause the program until the selected task is running
