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 checkbox for the
Function block release by EN is
necessary
parameter must first be enabled
C_ Counter input, counts with every rising edge
D_ Count direction
0: up counting
1: down counting
SE The starting value at SV is applied whenever
there is a rising edge at this input
RE Reset
1: QV=0
Reset the counter to zero
(DWord)
SH Upper Threshold Value Integer value range:
-2,147,483,648 to +2,147,483,647
SL Lower threshold value
SV Start value (Pre Set) When there is a rising edge at SE, this
value will be applied as the counter
value.
Integer value range:
-2,147,483,648 to +2,147,483,647
Assigning operands
You can assign the following operands to the function block inputs that are numeric
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:
Operands Bit inputs
Constant 0, constant 1 x
