10-23
Station status 1
Table 10-13 Structure of station status 1 (Byte 0)
Bit Description Remedy
0 1: DP slave cannot be addressed by DP master. • Is the correct DP address set on the DP
slave?
• Is the bus connector in place?
• Does the DP slave have power?
• Correct configuration of the RS485
Repeater?
• Perform a reset on the DP slave.
1 1: DP slave is not ready for data exchange. • Wait for the slave to complete startup.
2 1: Configuration data sent by DP master to the DP
slave is inconsistent with slave configuration.
• Was the software set for the correct
station type or DP slave configuration?
3 1: Diagnostic interrupt, generated by CPU RUN to
STOP transition
0: Diagnostic interrupt, generated by CPU STOP to
RUN transition
• You can read the diagnostic data.
4 1: Function not supported; e.g. changing the DP
address at software level
• Check configuration data.
5 0: This bit is always "0". • -
6 1: DP slave type inconsistent with software
configuration.
• Was the software set for the right station
type? (parameter assignment error)
7 1: DP slave was configured by a DP master other
than the master currently accessing the slave.
• The bit is always 1 if, for example, you are
currently accessing the DP slave via PG or
a different DP master.
The configuring master's DP address is
located in the "Master PROFIBUS address"
diagnostics byte.
Station Status 2
Table 10-14 Structure of Station Status 2 (Byte 1)
Bit Description
0 1: The DP slave requires new parameters and configuration.
1 1: A diagnostic message was received. The DP slave cannot resume operation until the error
has been cleared (static diagnostic message).
2 1: This bit is always "1" if a DP slave exists with this DP address.
3 1: The watchdog monitor is enabled on this DP slave.
4 1: DP slave has received control command "FREEZE".
5 1: DP slave has received control command "SYNC".
6 0: This bit is always "0".
7 1: DP slave is disabled, that is, it has been excluded from cyclic processing.
