This two Variables are used to specify the type of connected external temperature sensor and the used communication protocol between the sensor and the control system of the TCD.

Which sensor types and protocols and combinations are supported is device dependent. Especially when the CommunicationProtocolType has the value 1 (LOCAL), the ThermocoupleType could 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 Object of ClosedLoopControlType (defined in OPC 40083) the client can do settings for the closed loop control for the sensor.
LeakStopperType is an optional component of DeviceZoneType and is used for switching the leak stopper mode.
