I'm not sure what the problem is here v2020 - temperature controller set point, input via touchpanel - data type bcd I now need a variable that's that setpoint minus 30. I have: sp1 ----- ldd v2020 subd k30 outd v2030 For some reason, v2030 is the same value as v2020. If i substitute subd for mul(multiply), i get the correct answer. I 've also tried inserting k30 into a v-variable, then using that with my subd, but that didn't work either. I think i have a number format type of issue, any help is appreciated.

ok, i tried using ld, sub and out instead of the double words, and it seems to be working.
