Im using TIA V.12 and S7-1200 PLC In the older versions of the S7 i could define an array in SCL as follows. VAR Index: int array [index]: int END_VAR So the size of my array was depending of what was entered in the "Index" Is it not possible to do this in TIV V.12?

Hello, You mean you want to have an array with changing dimension in runtime?This what we do in "older versions of the S7" and I think what you plan to do is not possible for SCL for S71220. [code]FUNCTION_BLOCK FB1 VAR_TEMP // Temporary Variables END_VAR VAR // Static Variables index:INT; test1:ARRAY[0..9]OF INT; ///OK test2:ARRAY[0..index]OF INT; //invalid constant END_VAR // Statement Section ; END_FUNCTION_BLOCK[/code] Best regards Hamid Hosseini
