Move function block help

[bunschi]

hi all,

I need help, I'm trying to make a simple function block to move the data of 3 inputs position 1 to 3, to  3 consecutive address starting from the input address "position_data". Please see attach picture and my current approach which is not working. Thank you.

A DINT = 2 x Words

Your inputs are DINT's and you are trying to move them into 3 consecutive WORD addresses.

I wonder why FB for such a small and simple task?
As long as the program memory allows, I would simply rewrite it as many times as necessary, in the main program.
FBs are data memory and scan time significant consumers.

i did this for simpler appearance, i make this program at home and i cant be on actual site to adjust these parameters and the technician that will adjust this doesn't have enough knowledge on this matter, and i don't want him to mess around the program. its easier if it only have hmi.
