Multitasking
The control can process 3 cycles simultaneously (Task). The user can
enter a program in each of these 3 tasks. In each task, one instruction
(command) is processed within the NC cycle time.
When programming Tasks 1 through 3, take note of the following:
• The same subroutine may not be called up by more than one task at
the same time!
• Movements of a given axis may not be initiated by more than one task
at the same time!
• Prior to activation of Task 3, make sure that a program is present at its
start instruction!
Task 1 runs only in Automatic Mode. Program execution begins after a
Task 1
`Start´ and ends with a `Stop´ command. After re-entering Automatic
Mode, the program counter resets to 0000 with each start command. If
the start command follows execution of a prior immediate stop, the
program continues from the point of interruption.
Normally, only Task 1 is in operation.
Example:

Task 2 is activated only if it has been enabled in parameter AA00. That is
Task 2
also where the start instruction that begins the program in Task 2 is
entered for each start following re-entry into Automatic Mode.
