12.10 : Function block 1 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. 12.15 is used
to adjust the value
of the ramp

• If
12.10
equals 2, 3, 4 or 5:
When the result of the calculation is greater than or equal to
32767, output 12.11 is limited to 32767.
When the result of the calculation is greater than or equal to
-32768, output 12.11 is limited to -32768.
• If
12.10
equals 5:
To avoid a calculation error if V2 = 0, the result of the operation
will be 0.
• If
12.10
equals 9:
To avoid a calculation error, the absolute value of the signal V1
is taken before calculating its square root or cube root.
12.11 : Function 1 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.
12.12
: Function block 1 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.
12.13 : Function 1 variable 1 scale
Adjustment range : ± 4.000
Factory setting : 1.000
Format: 16 bits
Used to scale variable 1 before processing.
CAUTION:
The value at the output of the scaling can only be between
-32767 and +32767. Take this into account according to the
adjustment range of the source parameter.
12.14 : Function 1 variable 2 scale
Adjustment range :± 4.000
Factory setting : 1.000
Format: 16 bits
Used to scale variable 2 before processing.
CAUTION:
The value of the scaling output can only be between -32767
and +32767. Take this into account depending on the
adjustment range of the source parameter.
12.15 : Function 1 applied factor
Adjustment range : 0.00 to 100.00
Factory setting : 0.00
Format: 16 bits
Depending on its function, the internal variables processing
block may require an associated parameter.
If the block is used to create a first-order filter, the associated
parameter is used as a time constant; if it is used to generate a
ramp, this parameter is used to adjust the ramp value
(in seconds). The ramp time corresponds to the time for changing
from 0 to 100% of the maximum value of the source parameter.
If the block is used as a power, this parameter is used as
follows:
Function Associated parameter value

12.16 to 12.22 : Not used
12.23 : Comparator 2 source
Adjustment range : 0 0.00 to 21.51
Factory setting : 00.00
Format: 16 bits
This parameter defines the variable that is to be compared to
the configured threshold.
The absolute value of the variable is used. Only non-bit
parameters can be programmed as the source.
If an unsuitable parameter is programmed, the input value is
taken as equal to 0.
12.24 : Comparator 2 threshold
Adjustment range : 0.0 to 100.0%
Factory setting : 0.0%
Format: 16 bits
This parameter is used to set the comparator trip threshold.
The threshold is expressed as a percentage of the maximum
value of the compared variable.
