What? Why?
If you would like to evaluate strings for program flow based on the text the TEST instruction is a possible option.
What? Why?
I'm guessing they want to do something like late binding, but for I/O names instead of PROC names.
You can build an io name and connect it to an Aliasio then use the alias
60 signals to define or writing a routine/routines that evaluates the state of those signals?
i wrote this in 10 minutes You have to try and give it better names but it should work like this
PROC VARtest()
If dinput(diVar("PLC_DI80_OrderReq_Cnv"+NumToStr(nCnvNum,0)+"Chute"+NumToStr(nMagNum,0)+"_"+NumToStr(nChuteNum,0)))=1 then
SetDoVar("PLC_Do80_OrderAck_Cnv"+NumToStr(nCnvNum,0)+"Chute"+NumToStr(nMagNum,0)+"_"+NumToStr(nChuteNum,0)),high;
endif
If bdiVar("PLC_DI80_OrderReq_Cnv"+NumToStr(nCnvNum,0)+"Chute"+NumToStr(nMagNum,0)+"_"+NumToStr(nChuteNum,0)) then
SetDoVar("PLC_Do80_OrderAck_Cnv"+NumToStr(nCnvNum,0)+"Chute"+NumToStr(nMagNum,0)+"_"+NumToStr(nChuteNum,0)),high;
endif
ENDPROC
FUNC dionum diVar(string SignalName)
VAR signaldi TmpDiVar;
AliasIO SignalName,TmpDiVar;
RETURN TmpDiVar;
ENDFUNC
FUNC bool bdiVar(string SignalName)
VAR signaldi TmpDiVar;
AliasIO SignalName,TmpDiVar;
RETURN TmpDiVar=high;
ENDFUNC
PROC SetDoVar(string SignalName,dionum Value)
VAR signaldo TmpDoVar;
AliasIO SignalName,TmpDoVar;
SetDO TmpDoVar,Value;
ENDPROCim working with kuka atm and i wished i would be back at an abb. so much possibillities
Take a look of AliasIO instrucction:
Var signaldo myDo
Var string stTemp
stTemp := "PLC_DI80_OrderReq_CNV"+ValToStr(nCnvnum)
AIiasIo stTemp,myDo
If MyDo = 1 Then
(...)
what is with it? Doesn't work? Little more information what to look at 
Did the functions work i prepared for u?
NumToStr(nCnvnum,0) only thing i see
