 The Loop Control Unit handles analog I/O signals not in engineering units
but in percentage units.
At analog input, the converted values 0000 to 0FA0 (FF38 to 1068) Hex from
the Analog Input Unit for input 4 to 20 mA (3.2 to 20.8 mA) are converted to
0.00 to 100.00% (-5.00 to 105.00%) before they are processed by the Loop
Control Unit.
At analog input, the converted values F830 to 07D0 (F768 to 0898) Hex from
the Analog Input Unit for input -10 to +10 mV (-11 to +11 V) are converted to
0.00 to 100.00% (-5.00 to 105.00%) before they are processed by the Loop
Control Unit.
At analog output, the values 0.00 to 100.00% (-5.00 to 105.00%) are
converted to setting values 0000 to 0FA0 (FF38 to 1068) Hex before 4 to 20
mA (3.2 to 20.8 mA) is output from the Analog Output Unit.
Note Converted values (in the case of analog input) for 0 to 100% on the Loop
Control Unit and setting values (in the case of analog output) for 0 to 100%
on the Loop Control Unit are fixed to the same values as the user ranges.
However, in the case of isolated-type Analog Input Units (CS1W-
PTS01/02/03, PTW01, PDC01, PPS01, PTR01), the Analog Input Unit itself
has a range setting function. So, any values can be specified as the
converted values (on condition that the same setting as the range setting is
made).
