Under the
General
tab, change the name to
„sawtooth“.
22
Under the
I/O
tab, enter the values for the
block inputs, e.g.
•
X
= 1
•
LU = 11250
•
TI
= 5 ms
Click on
OK
.
The Properties dialog box is closed and the
function block inputs now have values
assigned.
23
First
click on
output QU and then on input S. The output QU (upper limit) is now coupled
back to input S (set).
24
Select
DAC
(analog output) from the block
family
ON/OFF
and locate it next to function
block INT.
Open the dialog box using
Edit > Object
properties
and change the name to "analog
output“.
Enter, for example under the
I/O
tab:
•
DM = 0
•
OFF= 0
•
SF = 1E6
Click on
OK
.
Select connection AD (hardware address),
and call-up the dialog box to interconnect the
object with
Insert >
Connect to operand
. Then mark
the selection window. Select the first entry
and click on
OK
The block inputs are parameterized.
The hardware address of the first analog
output channel is assigned.
25
In the "sawtooth“ block,
click
on output Y
and after this on input X in the "analog
output" block.
The sawtooth generator is connected to the
analog output.
All changes made in the CFC chart are immediately saved.
Proceed the same for the second sub-task (running lights) (from step 18).
Change into the SIMATIC Manager, open the CFC chart "running lights"
insert the function blocks into the CFC chart, parameterize and connect
them.
All of the necessary information (number of blocks, types and block
parameters) can be taken from the following diagrams. Arrange the first
function block and all others, via
Edit > Run sequence
in cyclic task T2. The connection between the
"sawtooth" block and the comparators is realized by changing the CFC
window (
Window > ...
).
