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
necessary
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 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:
