The BrakeType is used to describe the status of a brake. In this specification, it is only defined to model the backup brakes. A service brake status is provided by the BrakeReleased variable of the OPC 40010-1 (OPC Robotics) MotorType object. The Figure 13 shows an overview of this type.
Figure 13 – Overview BrakeType
The BrakeType represents the backup brake and contains its various components. The BrakeType is formally defined in Table 19.

The Identification Object provides identification information of the brake. It is specified in OPC 10000-100 and OPC 40001-1.
ParameterSet contains all the variables of the BrakeType. Variables are also referenced by an Organizes from Operational FunctionalGroup.
The components of the BrakeType have additional subcomponents which are defined in Table 20.
