Which sensor types and protocols and combinations are supported is device dependent. Especially when the CommunicationProtocolTypehas the value 1 (LOCAL), the ThermocoupleTypecould be set to a fixed value by the TCD.

Setting whether switching to external sensor is performed automatically (TRUE) or manually (FALSE). If TRUE, temperature control is regulated to the external sensor when the external sensor is plugged, and again switched automatically to the internal measurement site when the external sensor is unplugged.

With this Objectof ClosedLoopControlType (defined in OPC 40083)the client can do settings for the closed loop control for the sensor.

LeakStopperTypeis an optional component of DeviceZoneTypeand is used for switching the leak stopper mode.
