Diagnostics using the display
Y
ou can use the buttons at the front of the safety laser scanner to display the PROFI‐
NET alarms.
1. Press the OK button twice.
2. Diagnostics > PROFINET alarms
NOTE
N
ote: 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?
•
T
he 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.
