Process Value Scaling to Industrial Units

This function takes the value scaled to industrial units with respect to the input signal's zero point and
span point, and outputs it to the CPU Unit as the process value. Because of this, no user program is
required at the CPU Unit for scaling.
It also possible to set the process value scaling zero/span point in reverse to create an inverse relation-
ship.

CJ1W-PDC15, PH41U
With the CJ1W-PDC15/-PH41U, the input range for thermocouple inputs, and platinum-resistance
thermometer inputs, or the user-set range for DC inputs can be set directly, and scaling can be set
for the range in industrial units. This eliminates the need for processing scaling in the user program.
It also possible to set the process value scaling zero/span points in reverse to create an inverse rela-
tionship.
With the CJ1W-PH41U, potentiometer input scaling is also possible.
