Figura 11 ALMGR Bloque de funcin EjemploALT Alternator Bloque de funcinDescripcinThe ALT label stands for Alternator Funcin.

This block is part of the Auxiliary category.FuncinThe Alternator (ALT) bloque de funcin is typically used to alternate the starting sequence of a group of pumps, valves, filters, etc. Each block accepts up to 16 Entradas and controls up to 16 Salidas.There are four unique alternation styles used to control the Salida starting sequence so that you can limit the amount of repeat or continuous usage of a single device (pumps, valves, etc.). If an Salida device fails, or has been disabled, then an alternate device will be used in order to meet the requested demand. You may specify the alternators active Salidas and the order in which the Salidas are manipulated.Each configuration is limited to a maximum of 6 Alternator bloque de funcins.EntradasIN1 IN 16 =. Sixteen digital Entradas for requesting an Salida device. Unconnected pins default to OFF. DSBL = determines the status of the block:OFF = Status of block is RUN bloque de funcins process normally

If Activate Advance selected in configuration, an OFF to ON transition will rotate the Salida order selection.DRDYS = digital encoded device-ready signal, usually the bit encoded Salida of the DigitalEncoder Block (DENC) representing 16 digital states. No signal = 0Bit 1 = OUT 1, Bit 16 = OUT 16Ejemplo: If bit 3 is ON, "OUT 3" is enabled and its state can turn On/Off based on the AlternatorSequence. If bit 3 is OFF, "OUT 3" is disabled. Out 3's state will change to OFF.SalidasOUT1 OUT16 =. Sixteen digital Salidas, which turn ON and OFF based on the Entrada demand [IN1-16]. Salidas can be manually disabled by way of the Salidas tab in the block properties. Salidas can be programmatically disabled by the use of the "DRDYS" Entrada pin.ODIS = ON when any one of the Salidas (OUT) is manually disabled, otherwise OFFIDIS = ON when any one of the Entradas (IN) is manually disabled, otherwise OFFSTI = ON when the block state is RUN; OFF when the block state is OFF.Configurable ParametersThe Alternator properties dialog box is divided into four tab cards:GENERAL ENTRADAS SALIDAS SEQUENCE ORDERClick on the tab to access the properties for that tab.GENERAL tab

Style selectionsA style is a method used to control the cycling of the 16 Salidas. There are four styles from which to choose: Direct, Rotary (Last ON/First OFF), First ON/First OFF (FOFO), or Fixed (with Advance feature). This parameter is initially conFigurad here and can be altered from an operator interface.Important: A style change request does not take effect until all Entradas (IN1 - 16) are OFF.DIRECT Monitors up to 16 Entradas and maps them, using the user adjustable map order on the Salida tab, directly to the Salidas.If the Entradas selected are 1, 2, 3, 4, 5, 6 and the Salida order mapped is 6, 3, 4, 1, 5, 2; when Entrada 3 is activated, Salida 4 is enabled; or if Entrada 1 is activated then Salida 6 is enabled.ROTARY Uses the sum of the 16 Entradas that are set to ON to determine the required demand for Salidas. The Salida order is managed in a Last ON/First OFF basis (LOFO). If the Entradas selected are 1, 2, 3 and the mapped sequence is 1, 2, 3 the alternator sequence changes when NO Salidas (pumps) are required or there is a request to Advance (see Activate Advance).Depending on the capacity required, Salidas 1, 2, 3 come on in order. When the demand falls, Salida 3 goes OFF, then Salida 2, then Salida 1. When Salida 1 turns off, the Rotary sequence advances and Salida 2 starts the next cycle.If an Entrada pin is set to not available, then that Salida is forced to OFF and the next available Salida in the mapping order is turned ON. If the previously bypassed Salida later becomes enabled, then it will not be used until the demand increases.58HC900 Hybrid Control Designer Bloque de funcin Reference GuideRevision 1410/09Bloque de funcins ALT Alternator Bloque de funcinFOFO Uses the sum of the 16 Entradas that are set to ON to determine the required demand for Salidas. The Salida order is managed in a First ON/First OFF basis (FOFO). If 3 Entradas are ON (no mapping), the Alternator sequence changes (first one in the list moves to the end of the list) as the Entradas turn OFF or, when there is a request for Advance (see Activate Advance).If an Entrada pin is set to not available, then that Salida is forced to OFF and the next available Salida is turned ON. If the previously bypassed Salida later becomes enabled, then it will not be used until the demand increases.FIXED Uses the sum of the 16 Entradas that are set to ON to determine the required demand for Salidas. The Salida order is managed in a First ON/First OFF basis (FOFO). If the Entradas selected are 1, 2, 3, 4 and you map a fixed sequence 4, 2, 3, 1 the sequence will not change unless you select the Advance feature (see Activate Advance). It takes a direct command (OFF to ON signal) before the Salida order map rotates to the 2, 3, 1, 4 sequence.If an Salida pin is not available then that Salida is forced OFF and the next available Salida in the mapping order is turned ON. If the previously bypassed Salida later becomes enabled, then it will not be used until the demand increases.Activate advanceUsed with all styles except Direct. If you select Activate Advance (click on box on General tab to select), an OFF to ON transition of the ÂDV Entrada pin will rotate the Salida order sequence. Make before Break selection determines how this is done for Rotary and FOFO only.Make before breakThis feature works on Entrada demand and with the Advance Entrada, it is available for Fixed, Rotary and FOFO styles.When the ALT bloque de funcin receives an Advance Entrada (ÂDV pin) and Make before Break is selected (click on box on General tab to select) the next Salida in the sequence is activated before deactivating an Salida. When the selection box on the General tab is not selected (Break before Make) the Salida is removed before advancing the sequence and activating the next Salida. The ON and OFF Delay Timers are used with this feature.

These timers are the same times used with the Make/Break feature. There is one period for all On-delay times and one period for all Off-delay times.If an Salida is waiting in an On-delay timer and new Entrada conditions the Salida state to turn OFF, then the delay timer is reset, the Salida does not change state. If an Salida is waiting in an Off-delay timer and new Entrada conditions the Salida state to turn ON, then the delay timer is reset, the Salida does not change state.The timers operate in a cascade style.

FuncinThe Analog System Status Block is a bloque de funcin and is part of the Alarm/Monitor category. It provides read access to controller status values including those related to the Analog execution cycle. The Salida may be connected to bloque de funcin Entradas. The Salidas may also be connected to signal tags for operator interface monitoring. The ASYS System monitoring block is assignedblock number 1.Power Noise Rejection SelectionWhen you click on the ASYS bloque de funcin on a diagram, the "Controller System Parameters" dialog box opens. The 50 or 60 Hz selection is used to establish the integration times for analog to digital conversion.

Firmware mismatch between the CPUs.

CAVG Continuous Average Bloque de funcinDescripcinThe CAVG label stands for Continuous Average.

This block is part of the Calculations category.FuncinProvides the average value of a single analog parameter for a user specified time period, plus the running (instantaneous) average within the time period. A running average value is updated at the end of each sample period. Time periods to 1440.0 minutes are supported. At the end of the time period, the running average value is transferred to I/O process Salida value. A hold Entrada allows excluding samples from the average when active.Cold Start On the first cycle after a cold start, the instantaneous average Salida is initialized to current Entrada value, the sample counter begins to increment, and the period timer begins to decrement (assuming that Reset is OFF). The previous average Salida is set to zero.Warm Start On a warm start, the calculations continue where they left off. There is no attempt to compensate for the time the power was off or to resynchronize with the time of day.EntradaENTRADA = Analog EntradaRESET = Controls the sample calculations.If OFF, the Entrada samples are accumulated, the sample counter is incremented, the time remainingdecrements and the average value is calculated and written to the Salidas.If ON, the Salidas are held at their last values, the internal accumulators and sample counters arecleared, and the time remaining is re-initialized to the full average period.If ON to OFF transition, the average Salida is set to the Entrada value, and the period timer begins todecrement.The RESET pin does not affect the previous average Salida value.HOLD = If OFF, calculations run as normal. If ON, Entrada samples are not accumulated and included in the average calculation, the time remaining continues to decrement. The Salida values are held at their last state prior to the OFF to ON transition.If the averaging period elapses while HOLD is ON, the instantaneous average will maintain the last calculated average value, the previous average is updated to this value, the internal accumulators and sample counters are cleared, and the time remaining is re-initialized to the full averaging period.SalidaI AVG = Instantaneous calculation of the current average.

DC Device Control Bloque de funcinDescripcinThe DC label stands for Device Control.

This block is part of the Auxiliary category.FuncinThe Device Control bloque de funcin is normally used to control pumps. Based on certain events listed in Table 38 the device will be placed into one of six states: READY, PRESTART, STARTING, RUNNING, STOPPING, DISABLED, or FAILED. The READY (off state) is the initial state of the bloque de funcin. Each configuration is limited to a maximum of 16 Device Control bloque de funcins. Forcing of Salidas is NOT permitted within this block.EntradasREQ = (run request) when ON [Logic 1], puts the device in the Starting / Running state. When OFF, puts the device in Stopping / Ready state.FDBK = feedback from the controlled device; ON = device has started, OFF = device has not started.ERR = (in) - ON when the controlled device reports a failure, causes the device control to transition to the FAILED state. OFF = No device failure.^RST = an OFF to ON transition will manually reset the control when it is in the FAILED state and return to the READY state.DIS = (disable) When OFF, the device control operates normally. When ON, immediately transitions to the DISABLED state, it prevents the device from starting if in the ready state or immediately shuts-down the device if it is currently starting up or running state.SalidasOUT = Primary block Salida the Salida is ON in the RUNNING and STOPPING states, else OFF.RDY = (ready) ON when the control is in the Ready State (the controlled device is off and waiting for a request to run), otherwise OFF.PRES = (prestart) ON while in the prestart state (a request to run the device has been received and the start delay timer is >0, otherwise OFF.STRT = (starting) ON while in the start state (start timer has expired and there is a request to start the device.

1This block is part of the I/O Blocks category.FuncinThe Funcin is used for measuring speed and rate. It reads a single frequency channel from a Pulse/Frequency/Quadrature Entrada module. The signal is scaled from the selected frequency span to the selected Salida range in engineering units, providing an Salida value in engineering units.The Entrada signal is rejected if it is below a selected pulse width. The frequency of pulses above this width must be within the range specified by Pulse Width (Range); otherwise the Salida goes to failsafe and a failure-to-convert error occurs.EntradaENABL = Level Entrada to enable block. Entrada is ignored if not connected and default state is enabled. If block is disabled the Salida goes to zero.SalidaFAIL = A Boolean value that turns ON when the Pulse/Frequency/Quadrature Entrada module reports a failure.OUT = The frequency Entrada value scaled to engineering units (after filters, ranges, bias, or failsafe conditions have been applied).( Frequency In - Frequency Span Low) *OUT = (Salida EU High - Salida EU Low) + Salida EU Low + Bias^Frequency Span High - Frequency Span Low JThe generic forcing of Salidas is permitted.EjemploSay you conFigura the block as follows.Pulse Width (Range) = 500sec (10Hz-500Hz)Frequency Span Low = 50HzFrequency Span High = 450HzSalida range in EU = 0 - 100Bias = 8Failsafe = Upscale (upper Salida range)Assume the module is receiving a 255Hz signal, including noise. Assume 2% of pulses are noise, that is, are less than the minimum pulse width 500 sec. The block rejects this 2% and does not count them in the frequency. The remaining 98% valid pulses are counted, which is an effective signal of 250Hz. From the Salida equation above,OUT = [(25050) / (450-50)] * (100 0) + 0 + 8= [200/400] * 100 + 8= 0.5 * 100 + 8= 50 + 8= 58 EUIf the frequency of the effective signal (>500 sec pulse width) changes to outside the specified range of 10-500Hz, a failure-to-convert error occurs and the Salida goes to failsafe, in this case upscale (100).Configurable ParametersTable 48 Frequency Entrada configuration parametersProperties GroupParameterIndex #Parameter DescripcinValue or Selection
