6.2.2.3 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 neces-
sary
parameter must first be enabled
RE
1: Sets the function block's internal counter for
the delay back to the value at TD.

I1
Bit input used to provide operand states from
the main program to the interrupt program

I2
I3
I4
(DWord)
TD
Delay until the interrupt program is started
Value range: 20 ms …999 990 ms
Resolution: 10 ms
Assigning operands
You can assign the following operands to the function block inputs that are numeric
inputs.
Operands Value inputs
Constant, timer constant

x
MD, MW, MB - Markers
x
NB, NW, ND - NET markers
2)
x
nNB, nND, nND- NET markers
2)
NET station n
x
IA - Analog input
x
QA - Analog output
x
QV - QV - Numeric output of a FB
x
1)
Only on function blocks T, AC
2)
Only on projects with ≥ 2 base devices on NET
You can assign the following operands to the function block inputs that are bit inputs:
