5.3.1 Addition and subtraction
5.3.1.1 [330] Add. O1=-O2=I1+I2-I3+P1-P2
Type Function
Type Function
I1 % positive input I1
O1 %
P2P1I3I2I1O1 −+ −+=
I2 % positive input I2
O2 % inverted output = -1
I3 % negative input I3
P1 % positive offset
I4 b Master Reset
P2 % negative offset
Description:
This function adds inputs I1 and I2 and subtracts input I3. In addition, a positive and negative
offset can be defined via P1 and P2, respectively.
P2P1I3I2I1O2O1 −+ −+=− =
The result of the addition is limited to ±327.67%. Interim results are not limited.
As long as status TRUE is present at I4 (Master Reset), the output value at O1 is 0.
Example:
I1=3240 (=32.40%) O1 = 32.40% + 56,13% - 270.28% + 3.90% - 3.22%
= -181,07% I2=5613 (=56.13%)
I3=27028 (=270.28%)
P1=390 (=3.90%)
P2=322 (=3.22%)
Input for parameters, e.g.:
32.40%
P2 = 390
Note:
Percentages [%] have two decimals.
For example: Value 12345
IN
= 123.45% = 1.2345
5.3.1.2 [331] Addition position with offset

Description:
This function adds inputs I1 and I2 and subtracts input I3. In addition, an offset can be speci-
fied.

The output value comprises a High word (O1) and a Low word (O2). The positions offset which
is added is also separated in High word and Low word.
As long as status TRUE is present at I4 (Master Reset), the output value is 0.
Note:
Output value O2 is not the inverted value of O1.
The output can be combined with inputs for position values (Long).
The function can also be used for ramp settings in configurations x40.
The availability of configuration x40 depends on the device series.
