4.9 Cross reference table
Crossreferenceisavailableinrmware1.22orlaterandinAquaProgversion4.90orlater.
Crossreferencetablecanbeset-upinAquaProgtooptimisethedataowinComli/Modbustothesupervisory
system.Register0-254(telegramtype0and2)canbedenedtoholdpreferreddatabyacrossreference
tableandcanbesetfordataofanyregister.SeefurtherinformationinComli/Modbus register manual.
Thereisthepossibilityforcertainrescalingofdata,e.g.Running time in seconds can be rescaled to minutes
withthefactor60.Thescalefactorcanbebetween0-32767.Withthefactor0norescalingisdone.
CertainsupervisorysystemsonlyhandlepositivevalueswhenusingtheComliprotocol.Settingscanbe
selectedfor2’scompliment+/-32767orpureintegers0-65535.Ifpositivenumbersareusedwill0bereturned
for negative values.
TheextendedComlitelegram(max65535reg.)isnota󰀨ectedbythecross-reference.
Togetherwiththecrossreferencetablethereisapossibilitytosetanindividualscalefactorbetween0and
32767,foreachpositioninthecross-referencelist.Whenreadingdata,thevalueisdividedwithcorrespond-
ingscalefactor.Whenwritingdatathevaluewillbemultipliedwithcorrespondingscalefactor.Scalefactoris
ignored when set to 0.
Fordataindoubleregisters(32bits),thehighestregisternumbershouldbeusedtogetherwithscalefactors.
Writingtothehighestdoubleregisternumberwillalsosetdatainthelowerregisternumberifscalefactoris
set.Ifscalefactorissettozero,eachregisterishandledindividually.
Manyregistersallownegativevalues(signed2-complementdata).Thiscancausesomesystemstotreat
negativedataaslargepositivenumbers(ex.–1isreadas65535bythesystem).
Toavoidanyissuesthereisapossibilitytoindividuallysetcrossreferenceregisterstoonlypositivedata.
Negativevalueswillgivezeroreadout.
NOTE! CrossreferencetableareonlyavailabletosetupinAquaProg.InthemenusofCA511youhavepossibilityto
activate or deactivate the table.
IO-bits IO0-255canberedirectedtoanyIOnumberwhencrossreferencetableisenabled.
 IO-bit0-255isalsoavailableinregister312-327.Crossreferenceenabledisusefulinsystemsthatoptimise
data screens into single messages.
