This information model provides information about process values, for example provided by actuators or sensors. In 6.2, the integration of such devices as components of a machine is described. This includes information about the identification of a device as well as health information and specific errors. In 9.1, the VariableType representing process value setpoints is introduced. In 6.4, an ObjectType using the VariableType and providing the process value as well as adding additional mechanisms for alarming and zero-point adjustment is described. Examples of the overall usage of process values are described in 6.5.
