Siemens SIMATIC ET 200S IM151-1 FO STANDARD - Station Statuses 1 to 3

Error and system messages
4.4 Diagnostics with STEP 7
IM151-1 FO STANDARD interface module (6ES7151-1AB05-0AB0)
42 Manual, 02/2010, A5E01075965-03
Note
The length of the diagnostics frame varies depending on the parameter assignment:
 Between 6 and 62 bytes in DPV0 mode
 Between 6 and 110 bytes in DPV1 mode
You can identify the length of the last received diagnostics frame in
STEP 7 by referring to
the RET_VAL parameter of the SFC 13.
4.4.3 Station statuses 1 to 3
Definition
Station statuses 1 to 3 provide an overview of the status of a DP slave.
Structure of station status 1 (byte 0)
Table 4- 3 Structure of station status 1 (byte 0)
Bit Meaning Cause/Remedy
0 1: The DP slave cannot be accessed by the DP
master.
 Is the correct PROFIBUS address set on the DP slave?
 Is the bus connector plugged in?
 Is the DP slave connected to the voltage supply?
 Is the RS-485 repeater set correctly?
 Has the DP slave been reset?
1 1: The DP slave is not yet ready to exchange data.
 Wait, the DP slave is currently starting up.
2 1: The configuration data transferred from the DP
master to the DP slave does not match the slave
configuration.
 Has the correct station type or the correct DP slave
configuration been entered in the configuration software?
3 1: External diagnostics information is pending.
(Group diagnostics display)
 Evaluate the ID-specific diagnostics information, the
module status, and/or the channel-specific diagnostics
information. As soon as all errors have been eliminated,
bit 3 will be reset. The bit will be set again when there is a
new diagnostics message in the bytes of the
aforementioned diagnostics.
4 1: The required function is not supported by the DP
slave (for example, changing the PROFIBUS
address by means of software).
 Check the configuration.
5 1: The DP master cannot interpret the response of
the DP slave.
 Check the bus configuration.
6 1: The DP slave type does not match the software
configuration.
 Has the correct station type been entered in the
configuration software?
7 1: Parameters have been assigned to the DP slave
by a different DP master (not the one that currently
has access to the DP slave).
 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" diagnostics byte.
