Flashes
• Station failure
• At least one of the assigned slaves cannot
be addressed
• Check whether the bus cable is connected to the
CPU 410 or the bus is interrupted.
• Wait until the CPU 410 has started up. Check the DP
slaves if the LED does not stop flashing. If possible,
evaluate the diagnostics of the DP slaves with direct ac-
cess via the bus.
Diagnostic addresses for the DP master
You assign diagnostic addresses for PROFIBUS DP for the CPU 410.
When configuring the DP master, you specify a diagnostic address for the DP slave in the
associated project of the DP master.
This diagnostic address is used by DP master to obtain information about the status of DP
slave or a bus interruption.
