SignalConditionSet is a container object for the condition parameters of the signal. It is inherited from AnalogSignalType and has an additional interface reference to ITocSignalConditionSetType to add TOC signal specific condition variables.

The components of TocSignalType have additional references which are defined in Table 161.
