6. Function blocks
6.1 Manufacturer function blocks
The function block and its parameters
Function block inputs
Description
Note
(Bit)
EN
1: Activates the function block.
The check-
box for the
Function
block release
by EN is
necessary
parameter
must first be
enabled
(DWord)
I1
Comparison value 1
Integer value
range:
-2,147,483,648
to
+2,147,483,647
I2
Comparison value 2
F1
Gain factor for I1 (I1 = F1 * value)
Default value = 1
F2
Gain factor for I2 (I2 = F2 * value)
Default value = 1
OS
Offset for the value at I1,
I1 OS = OS + actual value at I1;
HY
Switching hysteresis for value at I2.
To calculate the hysteresis band (dead band) limited by the
upper and lower hysteresis threshold), the function block
takes into account the value HY as well as positive and neg-
ative components.
I2 HY = Actual value at I2+ HY,
I2 HY = Actual value at I2 - HY);
Assigning operands
You can assign the following operands to the function block inputs that are numeric
inputs.
Operands
Value inputs

NB, NW, ND - NET markers
x
nNB, nND, nND- NET markers
NET stations n
x
IA - Analog input
x
QA - Analog output
x
QV - QV - Numeric output of a FB
x
You can assign the following operands to the function block inputs that are bit inputs:
