A process image with
F_iPar_CRC is used,
but value 0 is speci‐

b
Use process image without F_iPar_CRC.

Diagnostics using the display
You can use the buttons at the front of the safety laser scanner to display the PROFI‐
NET alarms.
1.
Press the OK button twice.

PROFINET alarms
NOTE
Note: Active alarms are also displayed in the
CPU diagnostics buffer
in Safety Designer
and in TIA Portal.
Why does “Waiting for input” appear on the display?
•
The safety laser scanner has not yet received a valid bit from the controller for
selecting a monitoring case.
•
There is an error in the PROFINET/PROFIsafe parameters.
S3000 PROFINET vs microScan3 - PROFINET
If the microScan3 - PROFINET is replacing a safety laser scanner of type S3000 PRO‐
FINET, take into consideration that the process image has a different structure even
though the size of the process image remains the same at 6 bytes.
