Hi,
    Sorry to bother you, I have some trouble which pullze me some time, could you please give me some advice.
    I am trying to control a step motor.
    Now I want to set a number(60) to pv(um distance), send the number*20(60*20=1200) to device. I think CALC would be useful. I could not understand CALC well though I have RRM 3-14. 
    The following code is what I do.

Thanks!

*******devKohzuAries.db

record(longin,"RPS")  # send to device
{
    field(DESC, "move relativly")
    field(DTYP, "stream")
    field(INP,  "@devKohzuAries.proto RPS $(PORT) $(A)")
    field(FLNK,"um distance")
}
record(calcout,"um distance")  
{
    field(DTYP,"stream")
    field(OUT,"@devKohzuAries.proto RPS $(PORT) $(A)")
    field(CALC,"A*20")
    field(INPA,"um distance.VAL")
}

********  devKohzuAries.proto 
RPS{
    out "\x02RPS1/5/%d/0";
}
