The SupervisionProcessFluidType provides Variables used for monitoring the Pump process fluid. It is formally defined in Table 37. For the generation of events, the SupervisionProcessFluidType has references to the four Namur NE 107 statuses defined in OPC 10000-100. The InputNode Property of the Alarm shall contain the NodeId of the Component.
