13.3 ThermocoupleType and CommunicationProtocolType

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 HRD.

The TypeDefinition for both Variables is MultiStateValueDiscreteType, so the Properties EnumValues and ValueAsText shall be filled with the supported values out of Table 15 and

Table 16.

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 HRD. A server can provide manufacturer specific values with EnumValues ≥ 100.
