Posted 7 Oct 2022 (edited) Hello there. How to transfer data from one memory area to another using macro ? Data Type - Double Word Length - 4 Format - BIN Integer - 3, Decimal - 1 From Area - D To Area - LW Edited 7 Oct 2022 by SillyBoy Share this post Link to post Share on other sites
Posted 7 Oct 2022 Why use a macro? If you use a data transfer property you can grab a double from the PLC and move it to the LW memory: Share this post Link to post Share on other sites

So I guess it will be easy to use macro. Share this post Link to post Share on other sites

Its been a while since I made an NB macro - I'll look through an old program later today Share this post Link to post Share on other sites

Posted 7 Oct 2022 So The trick here is to transfer the data as Unsigned Integers (or any 16-bit variable) and transfer twice as much as you need. You can't create Double Arrays in the macro environment so this is the only workaround I found. The data is still in tact as you can see in the HMI - it is being displayed as a double. 1 person likes this Share this post Link to post Share on other sites
