SCL loop through bits

[Automatic_walrus]

Hello again,

SCL struggles continue but this time I'm trying to scan for 0 statuses in an array of boolean variables. Any ideas how to implement this?

 

[L D[AR2P#0.0]]

How big is the array and what processing is required when you find a zero??

 

[Lare]

maybe something

FUNCTION FC100 : VOID

VAR_TEMP

    i: INT;

   END_VAR



VAR_INPUT

    in1 : arr_data; //data to compare, UDT array of bool [1..100]



END_VAR



VAR_IN_OUT

    bit_count : INT; //bit counter

END_VAR



VAR_OUTPUT

    cmp : BOOL; //compare result



END_VAR



    

bit_count:=0;

    

FOR i:=1 TO 100 BY 1 DO



IF in1.data = false THEN 

  

bit_count:=bit_count+1; //counting bits with false-state



END_IF;



IF bit_count >0 THEN    //count >0, at least one bit is false

    cmp:= true;        //set bit

    

ELSE

    cmp:=false;     //all bits are are true

  

END_IF;



END_FOR;







END_FUNCTION

Lare: that's more or less what I tried earlier myself. My DB consists of couple integer values and then an array [0..100] of bool. How can I access the array of my struct loop through that in SCL?

No worries anymore, solved the problem! Thanks everybody for support again

Pseudocode have little typing error.

End_for should be before

If bit_count>0 then

otherwise "cmp" can have 0-status for onescan even that there is bits with "1" status on array.
