Numbers(constants)orvariablescanbeusedfortimesandvalues.Thevariables
arethendefinedviatheVariablestab.Fortimeinput,thevariablemaybeusedas
avalueorasatrigger:
Variable (value):Meansthatthevalueofthevariablesisusedastimevalue.Vari-
able (trigger) meansthatthechannelsetforthevariableisused as a triggerchan-
nel.Atriggereventisarisingedge.Ifthistriggeroccurs,thevaluethatis
programmedintotheprogramstepforthetriggerisassumedasasetpointand
thenextprogramstepisthenstarted.Thismethodenablestimecontrolofapro-
gramsequencetobeexpandedbyaneventcontrol.

Cycle time:Thecycletimedeterminesinwhichtimeframethevaluesareoutput
betweentwoprogramsteps.Intermediatevaluesarelinearlyinterpolated,i.e.cal-
culatedusingalinearequation.Theintervalsbetweenprogramstepsusedinthe
tableshouldbeintegralmultiplesofthecycletime.
4.7.20 Statistics
Thissoftwarechannelenablesasourcetobeevaluatedwitharangeofstatistical
functions.
Moving minimum/maximum:Thisminimumormaximumiscalculatedfromacon-
figuredseriesofvaluesnumberingfrom2to1000values.
Movingindicatesthateachnewvaluefromthesourceisstoredtothedataseries
andtriggerscalculationoftheminimumormaximumfromtheaccumulatedvalues
andoutputoftheresult.Ifthenumberofvaluesreachesthespecifiedmaximum,
thedataseriesisthenfullandanewvaluefromthesourcethenoverwritestheold-
estvalue.
Adevicerebootoraconfigurationchangedeletesalltheaccumulatedvalues.
Block evaluation:Thenumberofvaluesinthedataseriesisdeterminedbythefre-
quencyofnewsourcevalueswithinanintervalsetbytriggerevents.Achangein
thespecifiedchannelproducesthetriggerevent.Severalstatisticalfunctionsare
availableinthismode.
Edge triggering:Theselectedfunctioniscalculatedatthetimeofthetriggerevent
fromthedataseriesthathasaccumulatedbetweentwotriggerevents.Aftercal-
culation,theresultisoutputandalltheaccumulatedvaluesaredeleted.
Level triggering:Whenalevelmovesfromanactivetoinactivestate,theselected
functionisappliedtothevaluesaccumulatedduringtheactivelevelperiod.The
resultisoutputandtheaccumulatedvaluesthendeleted.
Generate intermediate values:Whenenabled,theresultsbetweenthetrigger
eventsareimmediatelyoutputaftercalculation(witheachnewsourcevalue).
