12.25 : Comparator 2 hysteresis
Adjustment range : 0.0 to 25.0%
Factory setting : 0.0%
Format: 16 bits
This parameter defines the window within which the comparator
output will not change state.
The output will change to Enabled (1) when the variable
reaches the value of the thr (hysteresis/2).
The output will change to Disabled (0) when the variable goes
below the value of the threshold - (hysteresis/2).
The hysteresis is expressed as a percentage of the maximum
value of the compared variable.
12.26 : Comparator 2 output invert
Adjustment range : Disabled (0) or Enabled (1)
Factory setting : Disabled (0)
Format: 8 bits
This parameter is used to invert the comparator output.
Disabled (0):
Output not inverted.
Enabled (1):
Output inverted.
12.27 : Comparator 2 output destination
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the internal parameter which will be
assigned by the comparator output.
Only bit type parameters can be programmed.
If an unsuitable parameter is programmed, the output is not
sent anywhere.
12.28
: Function 2 variable 1 source
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the source parameter for variable 1 to
be processed.
Only «numerical» parameters can be assigned.
If an unsuitable parameter is selected, the value of the variable
will be 0.
12.29
: Function 2 variable 2 source
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the source parameter for variable 2 to
be processed.
Any «numerical» parameter can be assigned.
If an unsuitable parameter is selected, the value of the variable
will be 0.
12.30 : Function block 2 select
Adjustment range : See table below
Factory setting : O = V1 (0)
Format: 8 bits
This parameter is used to define the function of the internal
variables processing block.
HMI name Output Comment
0 O = V1 = V1
Used to transfer an
internal variable
1 O = V2 = V2
Used to transfer an
internal variable
2 O=V1+V2 = V1 + V2 Addition of 2 variables
3 O=V1-V2 = V1 - V2
Subtraction of 2
variables
4 =V1xV2/100 = (V1 x V2) ÷ 100
Multiplication of 2
variables
5 =V1/V2x100 = (V1 x 100) x V2 Division of 2 variables
6 =filter/V1
Creation of a first-
order filter
7 O= ramp/V1 = ramped V1
Creation of a linear
ramp. 12.35 is used
to adjust the value
of the ramp
8 O = abs (V1)

9 O = V1^

• If 12.30 equals 2, 3, 4 or 5:
When the result of the calculation is greater than or equal to
32767, output 12.31 is limited to 32767.
When the result of the calculation is greater than or equal to
-32768, output 12.31 is limited to -32768.
• If 12.30 equals 5:
To avoid a calculation error if V2 = 0, the result of the operation
will be 0.
• If 12.30 equals 9:
To avoid a calculation error, it is the absolute value of the V1
signal which is taken into account before calculating its square
root or cube root.
12.31 : Function 2 output destination
Adjustment range : 00.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter is used to select the destination of the
processed variable.
Any non-protected «non-bit» parameter can be assigned.
If an unsuitable parameter is selected, the value of the variable
taken into account is zero.
12.32
: Function block 2 output
Adjustment range : ± 100.00%
Format: 16 bits
Indicates the value of the function output as a percentage of
the adjustment range of the destination parameter.
