Back again for some advice. i need to take the output of a PID loop and scale it to 0-600 to send across Modbus to a GS-2 VFD. is there any easy instruction to do this? i try using a MATHBCD box with this expression ((k600-k0) / (k4095-k0) * v2205 . V2205 is the PID output. the result never comes off zero. is it because the division is getting rounded to zero? must be a simpler way.
