Structure Of Station Status 2 (Byte 1); Structure Of Station Status 3 (Byte 2) - Siemens ET 200S Manual

Commissioning and Diagnostics
Table 6-8 Structure of Station Status 1 (Byte 0), Fortsetzung
Bit Meaning
6 1: The DP slave type does not corres-
pond to the software configuration.
7 1: Parameters have been assigned to
the DP slave by a different DP ma-
ster (not the one that currently has
access to the DP slave).
Station Status 2
Table 6-9

Structure of Station Status 2 (Byte 1)

Bit
0 1: New parameters have to be assigned to the DP slave.
1 1: A diagnostic message has been issued. The DP slave will not work until
the fault has been corrected (static diagnostic message).
2 1: The bit is always set to "1" in the DP slave.
3 1: Response monitoring has been enabled for 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: The bit is always at 0.
7 1: The DP slave has been disabled, that is, it has been removed from the
processing in progress.
1
The bit is updated only if another diagnostic message changes, too.
Station Status 3
Table 6-10 Structure of Station Status 3 (Byte 2)
Bit
0 to 6 0: The bits are always at "0".
7 1:
6-32
S
S
S
There are more diagnostic messages than the DP slave can
store.
S
The DP master cannot enter all the diagnostic messages sent by
the DP slave in its diagnostic buffer (channel-specific diagnosis).
Cause/Remedy
Correct station type entered in the
configuration software?
The bit is always 1, for example, if you
access the DP slave with the programming
device or another DP master.
The PROFIBUS address of the DP master
that assigned parameters to the DP slave is
located in the "master PROFIBUS address"
diagnostic byte.
