The compiler send me an error. I am starting with the PLC Next and I can see some differences to the other PLC i used with ISAGRAF.

The selected resource ‚axcf2152:IEC 61131-3‘ does not support the program organization unit ‚ACTF‘.
The selected resource ‚axcf2152:IEC 61131-3‘ does not support the program organization unit ‚WORDS_TO_DWORD‘.
Could you please let me know what is the problem. I believes it is a firmware problem. I have just buy the Starterkit and it has a version 2022.0.4.

ACTF and WORDS_TO_DWORD can only be used in safety programming.

In that case which function I have to integrate two WORD MODBUS register to one DWord register to recover a real value.
Thank you
Yours
