Code sequences
7.1 Transferring code sequences via STEP 7 online access
"Code sequence" column
The "Code sequence" column shows the following information about the AS-i address via a
color code:
Gray
Green (without
check mark)
Green (with check
mark)
Yellow
Red

No code sequence is needed for the address.
A code sequence was taught but not transferred to the memory. Start
the transfer of the code sequence by double-clicking the "Transfer
taught code sequences" button.
The code sequence was transferred to the non-volatile memory.
Note:
This status is also displayed when the output control is activated for
this address. The code sequences for safe outputs are automatically
predefined in the F-CM AS-i Safety ST module. They are not
transferred to the non-volatile memory of the code sequences.
An error has been detected:
A code sequence was taught that is already being used by another
slave. The code sequence cannot be used. Replace the slave with a
different slave.
Warning or error:
The address is sending an incomplete or invalid code sequence.
Check whether both inputs of the safe input slave are assigned with
the "ON" signal. If required, actuate the associated safety contacts.
The contacts must be closed.
• Check whether a cross-circuit exists at the inputs. If necessary,
correct the wiring of the inputs.
