Tasks
Task Preemption Due to Task Priorities
When a task cycle starts, it can interrupt any task with lower priority (task
preemption). The interrupted task will resume when the higher priority task cycle is
finished.
NOTE: If the same input is used in different tasks the input image may change
during the task cycle of the lower priority task.
To improve the likelihood of proper output behavior during multitasking, an error is
detected if outputs in the same byte are used in different tasks.
WARNING
UNINTENDED EQUIPMENT OPERATION
Map your inputs so that tasks do not alter the input images in an unexpected
manner.
Failure to follow these instructions can result in death, serious injury, or
equipment damage.
