Programming Method(s) Controllers are shipped pre-programmed for a variety of common application sequences and allow parameter and setpoint input by the user.
Resident vs Non-Resident Program Execution Program remains resident in controller. Program setpoints are stored in non-volatile RAM.
Resident/Supervisory. This controller supervises the scheduling of other controllers.
Resident/Stand Alone. This controller contains its own schedule.
Non-Resident. This controller is dependent upon another controller for its schedule.
None. This controller has no scheduling features.
Other Information not provided
