The ControlGroupType is used to manage the control of the functionality provided by a FunctionalEntity or part of it. ControlGroups are used when some part of a FunctionalEntity is to be “controlled” by another FunctionalEntity or application. ControlGroups can be used by an application to help understand how the Variables (inputs, outputs, configuration) and Methods are logically related to each other in the application. ControlGroups utilize the LockingServices defined in OPC 10000-100. The ControlGroupType is illustrated in Figure 26.
