Can anyone please help me as I am unable to find instrcutions for code in SCL. L P##input_pointer // load adress of input pointer LAR1 L D [ AR1 , P#2.0 ] // load 32bit POINTER to source adress in DB48 T #source_adress // store as pointer to source adress L P##output_pointer // load adress of output pointer LAR1 L D [ AR1 , P#2.0 ] // load 32bit POINTER to destination in DB48 T #destination // store as pointer to destination Thank you! ------------------------------------------------------------------------------------------ Split from Indirect addressing SCL- PIW[#MyAddr].

It matters which CPU you are using. The S7-1200 and S7-1500 needs another approach which builds on the PEEK and POKE instructions.
