Guys Hi,

i would need to move/copy 8 different Bool variables to one byte.

Each Bool should go to another place in byte.

Example:

byte place 0.0 = bit1

byte place 0.1=bit2

byte place 0.2=bit3

I have tried to find on forums how to do it in STL but can't find it. I pressume this can't be done in Ladder.

Thank you for your help.

Dear Jacked,

thank you for your answer, but unfortunately i have checked all these posts before writing my question. unfortunately i haven't found anything useful or anything i was able to implement and that is working.

Please if you can point me to post that you are referring to. maybe i have missed it.

Thank you,

Thank you for your help.

From yours link i was able to find bits to word conversion so then i just adopted it from bits to byte.

Kind regards,

Nikola

Thank you,

yours code is very similar to my. I presume it also does the job.

Thanks,
