I am using Twincat2 for an old project, and get a array of chars from a TCP connection.

a sample sting is this: CMD,011,132654,38201,ABC,23

I would need to split this into single strings. So basically an array of strings, where myarray[0] is CMD, [1] is 011 etc..

I cannot figure out how to do this. TC3 has a split function, but how can this be done in TC2 in structured text?

Thank you

I have never used TC2, but here is how I would approach the problem:

1. Find position of the first , using FIND

position := FIND(sampleString, ',');

2. Assign characters up to this position to first string in the array using LEFT

myArray[0] := LEFT(sampleString, position-1);

3. Delete first partial string and , from the initial string using DELETE

DELETE(sampleString, position, 1);

4. Repeat until no , is found in the initial string, then assign what remains to the last element of the array
