6.5.2 Function blockGUID-C20AF735-FF25-411B-9EA6-11D595484613 V3 ENFigure 325: Function block6.5.3 FunctionalityThe generic runtime counter function MDSOPT calculates and presents theaccumulated operation time of a machine or device as the output. The unit of timefor accumulation is hour. The function generates a warning and an alarm when theaccumulated operation time exceeds the set limits. It utilizes a binary input toindicate the active operation condition.The accumulated operation time is one of the parameters for scheduling a serviceon the equipment like motors. It indicates the use of the machine and hence themechanical wear and tear. Generally, the equipment manufacturers provide amaintenance schedule based on the number of hours of service.6.5.4 Operation principleThe function can be enabled and disabled with the Operation setting. Thecorresponding parameter values are "On" and "Off".The operation of the generic runtime counter for machines and devices can bedescribed using a module diagram. All the modules in the diagram are explained inthe next sections.GUID-6BE6D1E3-F3FB-45D9-8D6F-A44752C1477C V1 ENFigure 326: Functional module diagramOperation time counterThis module counts the operation time. When POS_ACTIVE is active, the count iscontinuously added to the time duration until it is deactivated. At any time theOPR_TIME output is the total duration for which POS_ACTIVE is active. The unitof time duration count for OPR_TIME is hour. The value is available through theMonitored data view.The OPR_TIME output is a continuously increasing value and it is stored in a non-volatile memory. When POS_ACTIVE is active, the OPR_TIME count startsSection 6 1YHT530004D05 DSupervision functions600 615 seriesTechnical Manual
