must not be interrupted.
Wait until this is completed and the optical reader is opera-
tional.
Green, permanently on:
The optical reader is ready for operation
No error
ER
Red, permanently on:
The optical reader is in "Group error" mode
Possible causes when working with onboard
PROFINET IO:
• Bus communication is interrupted.
• Bus error (no physical connection to a
subnet / switch).
• Wrong transmission speed,
Full duplex transmission is not enabled.
• The IP address is incorrect.
• Bad configuration.
• Bad parameter assignment.
• Bad or missing device name.
• I/O controller not available / switched off.
Start the WBM to view the error message. Perform the
suggested corrective measures in the section "Error mes-
sages (Page 176)".
• Check whether the IP address or device name occurs
more than once in the network.
• Check the settings of the I/O controller.
R/S
Permanently off:
The optical reader is in "Stop" mode.
No error
Green, permanently on:
The optical reader is in "RUN" mode.
No error
LK
Permanently off:
There is no Ethernet connection to the opti-
cal reader.
• Check the connection to the Ethernet cable.
• Check whether the connected switch or other communi-
cations partner is operational.
• Check or replace the Ethernet cable.
Green, permanently on:
An Ethernet connection without data traffic is
available.
In order to start the WBM of the optical reader, you also
need a valid network configuration for TCP/IP. Here, for
example, you can use the Primary Setup Tool to create a
valid network configuration for TCP/IP.
Green flashing:
The optical reader is exchanging data.
