2101
High selector
Input 1 and input 2 are compared, and the larger of
the two is output. The 1st function code provides the
upper limit value and the 2nd one provides the lower
one.

Low selector
Input 1 and input 2 are compared, and the smaller of
the two is output. The 1st function code provides the
upper limit value and the 2nd one provides the lower
one.

Average of
inputs
This function receives two inputs (input 1 and input 2),
averages them, and outputs the result. The 1st
function code provides the upper limit value and the
2nd one provides the lower one.

Function
code
Function code S13 (PID command value): The scale
for setting value 0 to 20000/0 to 100% is converted
with the maximum scale and minimum scale. The 1st
function code provides the maximum scale value of
the range and the 2nd one provides the minimum
scale value of the range.

Clip and map
function
This function receives single input (input 1), clips a
pre-selected range which is specified with two function
codes from it, maps 0.00 to 100.00%, and outputs the
result. The 1st function code provides the maximum
scale value of the range and the 2nd one provides the
minimum scale value of the range. Use this to connect
to analog output terminals. This function can only be
assigned to a maximum of 2 steps.

Scale
converter
The input 1 scale is converted from the minimum scale
and maximum scale, and 0 to 100% is used for the
minimum scale to maximum scale. The 1st function
code provides the maximum scale value of the range
and the 2nd one provides the minimum scale value of
the range. The input 1 signal selection can only be
used for setting value 8000 to 8021. This function can
only be assigned to a maximum of 2 steps.

Quadratic
function
Input 1 is converted and output with the following
formula. KA, KB, and KC are in exponential form, and
are set for U92 to U97.
Output = KA x (input 1)
2
+ KB x input 1 + KC
The 1st function code provides the upper limit value and
the 2nd one provides the lower limit value.
Either (3001) or (3002) is available to use, and only
one of these functions can be used.
