COK Communication
OK
0:
IC220SDL953 is not parameterized or at least one of the safe
communication relationships is not running without any errors.
1:
Communication OK
IC220SDL953 is parameterized and safe communication is running
without any errors to all configured satellites.
If no satellites have been configured: IC220SDL953 is parameterized.
14
SA
Safety address
0:
The error message of the IC220SDL953 is displayed in bits 10 ... 0
together with the error class, number, and location (see "Errors:
Messages and removal" on page 8-1).
1:
Firmware startup after power up completed.
The VersaSafe address setting is displayed in bits 10 ... 0.
13
E
Device error
0:
No error messages pending at any modules.
1:
Group error message: A device error, a parameterization error, or an I/O
error has been detected in one of the connected satellites or in the
IC220SDL953 itself. This can be detected via the corresponding Dev-
Diag registers of the individual satellites.
12
PUR Power up
requested
0:
A power up is not expected.
1:
Following an error that cannot be acknowledged, the IC220SDL953 or
one of the satellites expects a power up.

OAR Operator
acknowledge
requested
0:
No request for acknowledgment.
1:
The IC220SDL953 requests an acknowledgment by the user.
Previously: VersaSafe communication detected an acknowledgeable
error resulting in communication being deactivated.

Bit 14 = 0: The error message of the IC220SDL953 is displayed in bits 10 ... 0
together with the error class, number, and location (see "Errors:
Messages and removal" on page 8-1).
Bit 14 = 1: The error message of the VersaSafe address setting is displayed in bits
10 ... 0.
OAR:
If safe communication is not running to one or more satellites, the OAR bit can indicate
that communication can be restored. The user restores communication by means of a
positive edge at the OA bit in Dev-Ack-LPSDO.
A positive edge at the OA flag acknowledges
all
currently pending operator acknowledge
requests from
all
satellites.
WARNING: Unexpected machine startup
If you do not want the machine to start up/restart automatically, configure the safety logic
accordingly.
