■ HOLD Function
During program operation, the time of “segment time” can be stopped by “HOLD function”.
When the controller is in “Hold”, the time of time events are also stopped. (PV events do not stop at this time.)
When program operation is held, time event and segment time are extended only by amount of the hold.
