2056 Comparator
6
Comparison function with hysteresis.
Input 1 is the input value of this function and
input 2 is not used.
The 1st function code provides threshold value
and the 2nd one provides hysteresis width.
If input 1 is (threshold value) or smaller, this
function outputs logical “1: True”. On the other
hand if input 1 is bigger than (threshold value +
hysteresis width), this function outputs logical
“0: False”.

2071 Window
comparator
1
Comparison function with limits.
Whether the value of the input is within a
preselected range specified with two function
codes determines the status of the output.
Input 1 is the input value of this function and
input 2 is not used.
The 1st function code provides upper threshold
value and the 2nd one provides lower threshold
value.
If input 1 is within the range (defined by the two
function codes), this function outputs logical “1:
True”. On the other hand If input 1 is outside of
this range, this function outputs logical “0:
False”.

This function has the inverted logic of “Window

2101 High
selector
High selector function.
This function receives two inputs (input 1 and
input 2), selects the higher one automatically, and
outputs it.
This function has output limiters (upper/lower)
specified with two function codes.
The 1st function code provides the upper limit
value and the 2nd one provides the lower one.

2102 Low
selector
Low selector function.
This function receives two inputs (input 1 and
input 2), selects the lower one automatically, and
outputs it.
This function has output limiters (upper/lower)
specified with two function codes.
The 1st function code provides the upper limit
value and the 2nd one provides the lower one.

2103 Average of
inputs
Average function.
This function receives two inputs (input 1 and
input 2), averages them, and outputs the result.
This function has output limiters (upper/lower)
specified with two function codes.
The 1st function code provides the upper limit
value and the 2nd one provides the lower one.
