The action is executed when the user-specified time has
elapsed since the activation of the step. If the step becomes
inactive before the user-specified time expires, the action will
not be executed.
The operation is the same as for "SD". Unlike "SD", however,
the action will not be performed if the step becomes inactive
before the user-specified delay time expires. Execution can be
aborted with the "R" AQ.
The action is executed when the step is activated, and is
terminated when the user-specified time expires. If the step
becomes inactive before the user-specified time expires,
execution will be aborted.
The action is executed for as long as the step is active.
If a final scan is enabled, the action is executed for 2 cycles
when the step is activated.
If a final scan is disabled, the action is executed for 1 cycle
when the step is activated.
The action is executed once when the step becomes active.
The action is executed once when the step becomes inactive.
Stops and resets the action when the steps is activated, if the
action is being executed by "S", "SL", "SD", or "DS". Actions
being executed by other AQs will be reset, but not stopped.
When an action is reset, the following operations are
performed:
- OUT/OUT NOT instruction: OFF
- TIM/TIMH instruction: Reset
- Other timer, counter, or shift register: Maintained
The action is executed when the step is activated, and
continues to be executed even after the step becomes inactive.
Execution can be aborted with the "R" AQ.
