Fill a group of D regs with 0 (Mits Q)

Hey Guys. Been looking all over the manuals but can't find an instruction (ladder) to fill a specified quantity of D registers with zero, or any constant for that matter. I could move data from another group of "safe" D registers, that ties up a bunch of them and there's no guarantee that they'll always be zero in years to come. Does anyone know a single function to do this? Thanks.

Don't have software handy at the mo, but from memory have a look at BRST command

i.e
-|SM400|---[BRST D1 K100]

Zero 100 words starting at address D1

Thanks, STL. It's the next one in the list (BKRST) "batch reset of bit devices". Typicli Mitsi: you need to do a word function? use a bit command Nice one

depends what plc - but doesnt ZRST D0 Dnnn do the same job (Zone reset)
