Handle LOTS of signals

Boteon

Hi!
I'm facing this situation: i want to be able to set specific virtual signals without huge TEST-CASE structures.

I'll try yo explain this better:
I'm receiving from an external source (e.g. the flexpendant or an external software via socket) the number of the signal i want to change. In order to maintain this structure flexible i want to manage something like 1000 signals equally divided in input and output ones.
Now, the number i received has to correspond to a specific signal. I would like to identify this signal without using a huge test-case structure. Is it possible in any ways? The name or the label of the signals are not important for my purpose.

Thanks,
Matteo

Interesting problem. Never done it in production, but making a string from the number then aliasing to that output seems to work in a virtual test.

    PROC SignalNameFromNum()

        !made virtual digital outputs = "do_61", "do_62", "do_63"
        VAR signaldo aliasOutput;
        VAR num signalNumber;
        VAR string SignalName;
       
        signalNumber:=62;
        SignalName:="do_"+NumToStr(signalNumber,0);
        AliasIO SignalName, aliasOutput;
       
        SetDO aliasOutput, 1;

    ENDPROC

Wow, brilliant solution! I didn't consider AliasIO because i thought it would accept only Signado variables. I'll try it. Thanks!!
