Array Of Proc in ABB

    So I am trying to create a loop to select programs in abb but i am having trouble creating an array of procedures.

    Here is the declaration and in the proc calls i am getting data reference error for the first index.

    CONST num NUM_STYLES = 7;

    PERS num styleNumbers{NUM_STYLES} := [20, 21, 22, 40, 41, 42, 10];

    PERS num styleFunctions{NUM_STYLES} := [Proc20, Proc21, Proc22, Proc40, Proc41, Proc42, Proc10];

    Can anyone tell is there any other datatype or way to create something like this.

    Approved the thread.

    You did not post what code is causing errors. Anyway, I have a feeling that you would benefit from reading this:

    How to call by variable, and how not to.

    Here a programmer hard coded the routine name to a string to be used in a Call by variable. It pretty much defeats the purpose of using a Call by Variable and creates extra steps as well. There are two ways to use a call by variable: 1. %MyRoutine%; where the string between the percent signs is the name of the routine to run. 2. CallByVar "MainTyp", nProg; The number value is automatically converted to a string and concatenated onto the…

    Lemster68 I want to create a for loop to select programs based on the input from plc which will select the program from the arrays that i have created instead of doing test case method this can be little shorter and cleaner since i have a lot of programs that i want to add to the list. but the array for calling the programs doesnot allow me since its not a number but does not take string either. For PERS num styleFunctions{NUM_STYLES} := [Proc20, Proc21, Proc22, Proc40, Proc41, Proc42, Proc10]; this I am talking about the procs are subroutines that i want to call.

    There are a few ways to do this in my mind.

    PERS string sProcs{7}:=["Proc20", "Proc21, "Proc22", "Proc40", "Proc41", "Proc42", "Proc10"];

    Lets say you have the names in a string array.

    You could call them through late binding.

    The syntax for proc call is a string inside % symbols.

    %"Proc22"%;
    But you could also write it like:

    %sProcs{1}%;

    You could also combine a base string with a number.

    %"Proc"+ValToStr(22)%;

    There is also an instruction that does this in the system called CallByVar

    From the manual:

    Example 1
    reg1 := 2;
    CallByVar "proc", reg1;
    The procedure proc2 is called.

    Hope this helps.

    So you have procedures with the same name just different suffix at the end, take at look about Dynamic procedure call CallByVar in the manual "RAPID Instructions, Functions and Data types", it lets you use a name and a numeric value which you can use from your array to call a proc.

    Selected a post as the best answer.

    Gilldur So if I am using string right and I want to call the procs according to the index this would work or not ?

    FOR i FROM 1 TO NUM_STYLES DO

    IF giStyleSelect = styleNumbers{i} THEN

    SETGO goStyleEcho, styleNumbers{i};

    styleFunctions{i}:="";

    styleFound := TRUE;

    BREAK;

    ENDIF

    ENDFOR the only part from this code that i need to make sure is that it will get the data styleFunctions{i}:=""; and call the proc

    Quote from cpanchal

    CONST num NUM_STYLES = 7;

    PERS num styleNumbers{NUM_STYLES} := [20, 21, 22, 40, 41, 42, 10];

    PERS num styleFunctions{NUM_STYLES} := [Proc20, Proc21, Proc22, Proc40, Proc41, Proc42, Proc10];

    It has occurred to me (I think) today that you think that you have declared a new datatype with the declaration CONST num NUM_STYLES:=7; Because I see the other PERS num styleNumbers(NUM_STYLES):= ....

    That is not how it works. The num after the type (VAR, PERS, CONST) is the datatype, already present in rapid.
