Mitsubishi FX word to bits

Hi, I'm a Mitsubishi newbe trying to get the 3 first bits of D0 into M1, M2 and M3 in a Mitsubishi FX2N PLC using GX Developer.

I'm trying [MOV D0 K1M1] but it doesn't seem to work.

Can anybody please explain why?

that should work... is the instruction scanned? is there anything else writing to the target bits (or D0...)?

Yeah, it did work. The problem was that there was nothing infront. I forgot that you have to use always on bits with Mitsubishi.Thanks
