Bit
Meaning
Cause/remedy
4
1: The required function is not supported
by the DP slave (modifying the PROFI‐
BUS address via software, for example).
Check the configuration.
5
1: DP master in not able to interpret the
answer of the DP slave.
Check the bus configuration.
6
1: The DP coniguration frame is not cor‐
rect (incorrect slave type, paramters)
Correct the preset and actual configuration.
7
1: The DP slave was configured by a dif‐
ferent DP master (not the master that cur‐
rently has access to the DP slave).
Bit is always 1 if you, for example, use the pro‐
gramming device or a different DP master to
access the DP slave.
The PROFIBUS address of the DP master
which configured the DP slave is located in the
"Master-PROFIBUS address" diagnostic
byte".
Station status 2
Table 6-17
Structure of station status 2 (Byte 1)
Bit
Meaning
0
1: The DP slave has to be re-configured.
1
1: there is a diagnostic message. The DP slave will not function until the error is elminated
(static diagnostic message).
2
1: The bit in the DP slave is always at "1".
3
1: The watchdog is activated on this DP slave.
4
1: The DP slave has received the "FREEZE" control command.
5
1: The DP slave has received the "SYNC" control command.
6
0: Bit is always at "0".
7
1: Bit is always at "0". Note: The bit is "1" when the station status is read by the DP master,
if the DP slave was deactivated in the DP master, in other words it has been removed
from current processing.
Station status 3
Table 6-18
Structure of station status 3 (Byte 2)
Bit
Meaning
0 to 6
0: Bits are always at "0".
7
1: There are more channel-related diagnostic messages than can be shown in the diag‐
nostic frame (diagnostic overflow).
