6.2.3.3 The function block and its parameters
Function block inputs
Description
(Bit)
EN 1: Activates the function block.
RE 1: Sets the actual time of the interrupt function
block back to the time at PD.
ST 1: Stops the interrupt function block's time
measurement.
0: The interrupt function block's time meas-
urement will continue.
I1 The states of the bit inputs from the main pro-
gram are provided to the interrupt program.
I2
I3
I4
(DWord)
PD Pulse pause time:
Value of the delay that must elapse before the
interrupt program is started.
Assigning operands
You can assign the following operands to the function block inputs that are numeric
inputs.
Operators
1)
Constant, timer constant
MD, MW, MB - Markers
NB, NW, ND - NET markers
nNB, nND, nND- NET markers
NET station n
IA - Analog input
QA - Analog output
QV - QV - Numeric output of a FB
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:
Operators
Constant 0, constant 1
M – Markers
2)
RN - Input bit via NET
SN - Output bit via NET (send)
2)
N - Net marker bit
2)
nN - NET marker bit NET station n
