Function Block Descriptions
Each of the next several pages graphically shows each of 
the RMH function blocks. Note that as you view each you 
will find text that is black and text that appears gray. The 
gray text represents inputs that are not currently available 
based on the function's defined use (red text). For instance 
when the defined use of the Analog Input function is set 
for RTD, TC Linearization will appear gray. Ranges speci-
fied in units or degrees F, if expressed in degrees C, range 
is smaller
Analog Input Function
Note:
This Function configures and connects physical inputs to 
internal functions. Control Loop primary source instance 
must match Process Value or Analog Input instance.
