ExampleVariantsRoomControlFCUSimple (FB) ¶ FUNCTION_BLOCK ExampleVariantsRoomControlFCUSimple Example how to deal with aggregate / plant variants using “external composition” This example function block implements a simple room control strategy using a fan coil unit. There are three variant aspects in ExampleVariantsRoomControlFCUSimple: the heat valve (type) the cool valve (type) the condensate pump (type) Despite the fact there are external elements for those three variant aspects ExampleVariantsRoomControlFCUSimple provides the related output values to help to get a better understanding of functionality during simulation / testing. Of course this example falls a bit short on complexity, but thats on purpose to focus on aggregate / plant variants using “external composition”. Real world FCU room controller need to have inputs / configuration for: energy level setpoints (see EnergyLevelSetpoint) sequence controller settings and manual control (see SequenceControl) fan coil settings and manual control (see FancoilContinuous) InOut: Scope Name Type Initial Comment Input eLevel EnergyLevel Energy level rRoomTemp REAL 22.0 Room temperature itfValveHeat IValveContinuous Heat valve - plugin your specific continuous valve here. itfValveCool IValveContinuous Cool valve - plugin your specific continuous valve here. itfCondensatePump IActuatorOnOff condensate pump - plugin your specific pump on/off here. xReset BOOL FALSE Reset itfDateTimeProvider Util.IDateTimeProvider Globals.g_dtpDateTimeProvider Source for the current date and time information in milliseconds since 1.1.1970 00:00:00.000 Output eModeOut HeatCoolOperationMode HeatCoolOperationMode.INACTIVE Operation mode. rHeatOut REAL Heat valve signal (0..100%). rCoolOut REAL Cool valve signal (0..100%). rFanSpeedOut REAL 0.0 Fan speed (0..100%). xCpumpOut BOOL FALSE Condensate pump. xError BOOL Error indication eErrorID Error Error ID
