Ok
Thanks

Yes. setbitwhilekeypressed, Kalle reports that sometimes it does reset when you release the key so always reset in plc then map the key that way it wont matter and if the hmi comms fails the key press is reset in the PLC.

Thanks for the example getting it now

I dont know why I wrote SetBitWhileKeypressed.
I meant to write SetBit.
Exactly like Kalle said, I evaluate the bit in the PLC, and unconditionally reset it.
