Station status 1 to 3
Definition
Station status 1 to 3 gives you an overview of the status of a DP slave.
Station status 1
Table 5–7
Layout of station status 1 (byte 0), ET 200R
Bit
Meaning
Cause/Remedy
0
1: The DP slave cannot be addressed by the
DP master.
The bit on the DP slave is always 0.
•
Is the right PROFIBUS address set on the
DP slave?
•
Are bus connection plugs/fiber-optic con-
ductors connected?
•
Does the DP slave have power?
•
Is the RS 485 repeater set correctly?
•
Perform reset on DP slave (power off/on)?
1
1: The DP slave is still not ready for data
communication.
•
Wait until DP slave has finished startup.
2
1: The configuration data sent to the DP slave
by the DP master do not match the actual
layout of the DP slave.
•
Has the correct station type or correct lay-
out
•
of the DP slave been entered in the configu-
ration
•
software?
3
1: An external diagnosis exists.
•
Evaluate the ID-related, the module status
•
and/or the device-specific diagnosis. As
soon
•
as all errors have been corrected, bit 3 is
re-set.
•
The bit is set again when a new diagnostic
message is entered in the bytes of the
above diagnoses.
4
1: The required function is not supported by
the DP slave (e.g., SYNC/FREEZE).
•
Check the configuration.
5
1: The bit is always 0.
NOTE
Is the bit 1 when the station status is read by
the DP master?
DP master is unable to interprets the response
of the DP slave.
6
1: The DP slave type does not match the soft-
ware configuration.
•
Compare the "should be" configuration with
the "actual" configuration.
7
1: The DP slave has been parameterized by
another DP master (not by the DP master
which currently has access to the DP
slave).
•
Bit is always 1 if, for example, you are just
accessing the DP slave with the PG or an-
other DP master. The PROFIBUS address
of the DP master which parameterized the
DP slave can be found in the "master
PROFIBUS address" diagnostic byte.
