6.6 Logic diagram
Modular Safety System 3RK3
158 System Manual, 10/2008, 926 2530-02 DS 02
Cell functions can be placed by the user
● Fail-safe and non-fail-safe input signals as well as fail-safe and non-fail-safe output
signals can be connected once to an input cell function.
● Only fail-safe and non-fail-safe output signals can be connected to an output cell function.
Note
If you do not observe the rules described above, you are either guided through editing,
i.e. incorrect connections are not possible, or a corresponding error or warning message
is displayed.
6.6.6 Messages during the consistency check - Logic
The consistency check is used to check whether the configuration is correct and complete.
A consistency check is carried out for the following actions:
● With the menu command "Edit" > "Check consistency"
● When a configuration is saved
● With the menu command "Target system" > "Prepare configuration test..."
The messages are displayed in the output window. By clicking on a message in the output
window, you can jump to the corresponding error location.
Logic diagram
The following messages exist for the logic diagram:
Rule Type Message Remedy
All address elements must
be assigned to valid
addresses. (Exception:
FAULT output)
Error Logic: Terminal not connected
<[element type]> (no. [element
number]).
Assign a valid address in the object
properties dialog of the address
element or of the associated
input/output element.
Non-fail-safe input signals
can only be added to a
safety circuit if they are
ANDed with a safe signal.
Warning Logic: Signal flow terminal <[element
type]> (no. [element number]): Non-
safety-relevant signal is connected
with a safety-relevant signal to a
safety output without ANDing.
Change the safety circuit accordingly.
Inputs of logic elements must
be connected.
Error Logic: Input <[element type]> (no.
[element number]) not connected.
Change the safety circuit accordingly.
Outputs of logic elements
must be connected.
(Exception: FAULT output)
Error Logic: Output <[element type]> (no.
[element number]) not connected.
Change the safety circuit accordingly
A function must not overlap a
page limit.
Warning Logic: The function element <function
name> (no. [element number])
overlaps the page limit.
Move the function or execute the
command "Realign graphic".
A function must not overlap a
connection.
Warning Logic: The function element <\1> [no.
\2] overlaps a connection.
Move the function or execute "Realign
graphic".
