Table 5-7 Layout Of Station Status 1 (Byte 0), Et 200R - Siemens SIMATIC ET 200R Manual

Commissioning and Diagnosis
5.5.1 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
1: The DP slave cannot be addressed by the
0
DP master.
The bit on the DP slave is always 0.
1 1: The DP slave is still not ready for data
communication.
2 1: The configuration data sent to the DP slave
by the DP master do not match the actual
layout of the DP slave.
3 1: An external diagnosis exists.
4 1: The required function is not supported by
the DP slave (e.g., SYNC/FREEZE).
5 1: The bit is always 0.
6 1: The DP slave type does not match the soft-
ware 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).
5–8
Meaning Cause/Remedy
• 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)?
• Wait until DP slave has finished startup.
• Has the correct station type or correct lay-
out
• of the DP slave been entered in the configu-
ration
• software?
• 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.
• Check the configuration.
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.
• Compare the "should be" configuration with
the "actual" configuration.
• 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.
