ExampleRoomAutomation (FB) ¶ FUNCTION_BLOCK ExampleRoomAutomation Example room automation This example function block implements a very simple room temperature control using a fan coil to demonstrate: how to implement a complex control strategy in CFC using CODESYS Building Automation library function blocks how to use certain room automation related function blocks how to use SequenceControl This example involves following real world application aspects: presence controlled energy level room temperature control using a fan coil Fancoil3Stage energy optimization (night cooling, energy lock, summer compensation) fast heat / cool at “pre-comfort” window alarm Watch out for comments in the implementation where those aspects are covered. outdoor air temperatur sensor room control panel including indoor air temperatur sensor, manual control elements (presence, temperature setpoint, fan speed) presence sensor fan coil (4-pipe system) window actuator window contact Air types ¶ Air types - terms, abbreviations and colors oriented towards DIN EN 16798-3 - see ExampleAirConditioning1 . Presence controlled energy level ¶ In this example energy level is selected by local information - presence information from room control panel and presence sensor. More complex scenarios might involve using a “pre-comfort” energy level controlled by building managment system / room occupancy control system. To keep the example simple, xPrecomfort := TRUE does switch the energy level from “economy” to “pre-comfort”, but doesnt effect an active energy level “comfort”. Dealing with “pre-comfort” is a bit more complex in real world applications. Night cooling ¶ Cooling down the room using cooler outdoor air is done using HeatCoolUsingOutdoorAir . Energy lock ¶ The energy lock function prevents energy consumption if window is opened. Nevertheless building protection is taken care for running the sequence controller with the related building protection setpoints. In case control actions are executed and energy is spent xBuildingProtectionActive is signalling this. The energy lock does imply an on-delay, so window needs to be open for tEnergyLockOnDelay before building protection setpoints are used. Also there is a tEnergyLockMaxTime limiting the duration of the energy lock function. Sommer compensation ¶ Sommer compensation is done shifting the setpoints (in “comfort” energy level only) using a CommandVariable to adjust setpoints. Fast heat / cool ¶ Fast heat / cool is about to bring a room the “comfort” conditions during “pre-comfort” mode because a switch to “comfort” is going to happen soon. Common use case - hotel receptionist does a checkin procedure, starting fast heat / cool right away. Window alarm ¶ Window alarm is signalled, if room is not occupied, window contact is signalling open window and night cooling does not open the window. Manual fan control ¶ Manual fan control can be done via room control panel if room is occupied. Hints ¶ Unused pins of function block instances are hidden, so refer to the function block documentation for more details. Caveats ¶ To keep complexity as low as possible this example omits the following real world application aspects worth mentioning: configuration missing (configuration of m_energyLevelSetpoint, m_sequenceControl etc. is not exposed on the ExampleAirConditioning1 VAR_INPUT section) input consistency checks (implausible measurement values, …) simplistic energy level selection - usually their is more complex state machinery in room control panel / building managment system / room occupancy control system “pre-comfort” energy level controlled by building managment system / room occupancy control system xError / eErrorID not computed from xError / eErrorID of function block instances used, see ExampleAirConditioning2 how to do this sensor / actuator process I/O not mapped (FB sensor inputs, m_windowActuator, m_valveHeat, m_valveCool, m_condensatePump, …) InOut: Scope Name Type Initial Comment Input xEnable BOOL TRUE Enable xPresenceSetting BOOL TRUE Presence signalled by room control panel rIdaTemp REAL 22.0 Indoor air temperature signalled by room control panel usiFanStageManual USINT (0..3) 0 Fan speed manual control requested by room control panel - 0 => off, or stage 1 .. 3 xFanStageManual BOOL FALSE Fan speed manual manual control requested by room control panel. xPrecomfort BOOL FALSE Enables the “pre-comfort” energy level. xFastHeatCool BOOL FALSE Enables the fast heat / cool mode. xPresence BOOL TRUE Presence signalled by presence sensor rOdaTemp REAL 10.0 Outdoor air temperature xWindowOpen BOOL FALSE Window contact signalling open window. xNightCooling BOOL FALSE Enable night cooling xEnergyLock BOOL FALSE Enable energy lock tEnergyLockOnDelay TIME TIME#10s0ms Energy lock on-delay tEnergyLockMaxTime TIME TIME#10m0s0ms Energy lock maximum duration xSummerCompensation BOOL FALSE Enable summer compensation 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 eLevel EnergyLevel Energy level eMode HeatCoolOperationMode Operation mode. xWindowAlarm BOOL Window alarm xBuildingProtectionActive BOOL There are control actions / energy consumption to keep indoor air temperature in the building protection setpoint range.

DailyMeanTemperature (FB) ¶ FUNCTION_BLOCK DailyMeanTemperature “warp clock”-enabled daily mean temperature. Computes the daily mean temperature based on outdoor temperature sampled at full hour. In case more than two samples are missing for some reason (outdoor temperature not valid, sampling time window missed), daily mean temperature is computed from main date samples (0:00, 6:00, 12:00 and 18:00). When does the daily mean temperature gets valid? ¶ The daily mean temperature can be computed after last full hour is sampled - means 23:00. So there is no valid daily mean temperature for the day before that. “Warp clock”-enabled ¶ Certain application domains base their functionality / algorithms on real world wall clock date/time. To develop such functionality it is helpful to have control over the application timeline to speedup testing or doesnt loose control on the timeline sitting on breakpoints. WarpClock and “warp clock”-enabled function blocks provides such a control if needed. For more details about “warp” time see WarpClock . To use “warp” time connect an accordingly configured WarpClock to itfDateTimeProvider. InOut: Scope Name Type Initial Comment Input rOdaTemp REAL 10.0 Outdoor air temperature xOdaTempValid BOOL TRUE Outdoor air temperature is valid xReset BOOL FALSE Reset the daily mean temperatur 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 rOut REAL daily mean temperature xValid BOOL daily mean temperature is valid xError BOOL Error indication eErrorID Error Error ID

HeatingCharacteristicCurve (FB) ¶ FUNCTION_BLOCK HeatingCharacteristicCurve HeatingCharacteristicCurve computes the approppriate water heating system supply temperature from outdoor air temperature. Application example ¶ Hot water heating systems are widely used in building automation and work with radiators, convectors or floor / wall heating pipes. Functionality ¶ HeatingCharacteristicCurve does compute the supply temperature using a simple linear equation, which is sufficient for most applications. rOutdoorTemp < 15°C: rSupplyTemp := rRoomReferenceTemp + rShift - rGradient * (rOutdoorTemp - 24.0) rOutdoorTemp >= 15°C: rSupplyTemp := rRoomReferenceTemp + rShift - rGradient * (1.8 * rOutdoorTemp - 36.0) rSupplyTemp is limited by rMinimumSupplyTemp and rMaximumSupplyTemp. Typical setup for radiators and convectors: rGradient 1.0 .. 1.5 Typical setup for floor / wall heating: rGradient 0.4 .. 0.7 Default settings are chosen for radiators and convectors. InOut: Scope Name Type Initial Comment Input rOutdoorTemp REAL 0.0 Outdoor temperature rRoomReferenceTemp REAL 20.0 Room temperature reference value rGradient REAL 1.2 Gradient rShift REAL 0.0 Parallel shift rMinimumSupplyTemp REAL 30.0 Minimum supply temperature rMaximumSupplyTemp REAL 75.0 Maximum supply temperature Output rSupplyTemp REAL Supply temperature
