Station statuses 1 to 3

Definition
The stations status 1 to 3 provides an overview of the status of a DP slave.
Station status 1
Table 9- 4 Structure of station status 1 (Byte 0)
Bit
0 1: The DP slave cannot be addressed by the DP mas-
ter. The bit in the DP slave is always 0.
1 1: DP slave is not ready for the data exchange.
2 1: The configuration data sent to the DP slave by the
DP master does not match the actual configuration
of the DP slave.
3 1: External diagnostics available.
4 1: The requested function is not supported by the DP
slave.
5 1: The DP master cannot interpret the response of the
DP slave.
6 1: DP slave type does not correspond to the software
configuration.
7 1: DP slave was configured by a different DP master
(not by the DP master that currently has access to
the DP slave).

Meaning Cause / remedy
• Is the correct PROFIBUS address set on the DP slave?
• Bus connector / FOC connected?
• Voltage on DP slave?
• RS 485 repeater set correctly?
• Has a reset been performed on the DP slave (switch off /
switch off)?
• Wait for the DP slave to complete start-up.
• Correct station type or correct configuration of the DP
slave entered in the configuration software?
• Evaluate the identifier-related, module status and / or
channel-related diagnosis. As soon as all errors are reme-
died the bit 3 is reset. The bit is reset when there is a new
diagnostic message in the bytes of the diagnostics indi-
cated above.
• Check the configuration.
• Check the bus configuration.
• Was the configuration software set for the correct station
type?
• The bit is always 1, for example, if you access the DP
slave with the programming device or another DP mas-
ter.
The PROFIBUS address of the DP master that configured
the DP slave is located in the "Master PROFIBUS address"
diagnostic byte.
