CarlesG Posts: 5 Rating: (0)	hello i have a little problem that I can not fix and wanted to know if any of you could help me, I make a FC in SCL to transfer data to a two-dimensional array of type [X1 .. Y1, x2 .. y2] of INT so indexed, not absolute addresses in the DB, if anyone has any idea how to do it would be fantastic. Best regards. Attachment example of the source.jpg (2201 Downloads)

Maybe something in there will answer your question(s), though to be honest, I do not know what your question really is.

If you need to fill rectangle with some defined numbers you can use solution hdhosseini provided. If you need to create array with undefined limits (i.e. array size definition inside PLC program) - thats impossible. The only thing i would add to solution above - if your 'rows' are quite big it may be better to write square are row-by-row (with SFC20 for ex) then element-by-element. A bit more complex coding, but can be way faster in case of large arrays as you have in example.
