The optional FunctionalGroup Analyses provides Objects and Methods for analyses that can be invoked on the Main Control System.
The optional FunctionalGroup Configuration provides Objects and Methods for configuring the behavior of the Main Control System.
The optional Object ElectricalCircuit provides Quantities for the electrical input of the Main Control System.
The optional FunctionalGroup Events provides Objects for alarms and conditions of the Main Control System. Of the available optional Objects in the EventsType, only Service and Warning are instantiated.
The mandatory FunctionalGroup Identification provides Properties to identify the Main Control System. The optional Variable DeviceClass has its ModellingRule changed to mandatory and its Value Attribute set to a specific value.
The optional FunctionalGroup Operational provides Variables for process data used during normal operation of the Main Control System, such as measurements, efficiencies, and states.
The optional FunctionalGroup Statistics provides Variables for statistical applications of the Main Control System, such as counters.
The InstanceDeclarations of the MCSType have additional Attributes defined in Table 22.
