called reverse path is created. Reverse paths cause a delay in the response time
because the output signal of the function block is only updated one logic cycle
later. Please take the delayed response time into account when using reverse
paths.
•
CPU markers cause a delayed response time.
•
For pulsed signals, a signal change may be delayed because the signal change
can only be taken into consideration by the test pulse in the subsequent logic
cycle. The logic execution time itself is not affected by this.

Adding an element
Approach
b
In the
CPU logic catalog
, selected the desired element and drag it onto the work‐
sheet using drag and drop.
7.6.7.3
Connecting elements
Approach
1.
Click and hold the blue square of an element.
2.
Drag and release the mouse pointer onto another blue square of an element (left
side).
✓
A connection between the input and output of the elements is indicated by a black
line.
Complementary information
•
You can only connect inputs to outputs and vice versa. Inputs are the blue squares
on the left side of an element. Outputs are the blue squares on the right side of an
element.
•
You can connect the output of a function block to multiple
downstream function
blocks.
•
You can connect the output of a function block to multiple physical outputs.
7.6.7.4
Configuring function blocks
Approach
1.
Double-click on a function block.
✓
The configuration dialog for the function block opens.
2.
Configure the desired parameters on the tabs of the configuration dialog.
Complementary information
When you click on a function block on the worksheet, the
FB group info
window displays
information about the relevant function block.

Testing the logic program
Testing the logic program
While the configuration is invalid, you will not be able to activate the simulation mode.
You will also not be able to transfer the configuration to the safety controller.
