Station status 1
Table 7-28 Setup of station status 1 (byte 0)
Bit Meaning Cause - remedy
0 1: The DP device cannot be ad‐
dressed by the DP master. The bit is
always "0" in the DP device.
• Correct PROFIBUS address set on the DP device?
• Are the bus connectors connected?
• Voltage on the DP device?
• Is RS 485 reporter set correctly?
• RESET performed on the DP device (power o/on)?
1 1: The DP device is not yet ready for
data exchange.
• Wait as DP device is starting up.
2 1: The conguration data transmit‐
ted by the DP master to the DP de‐
vice do not correspond to the struc‐
ture of the DP device.
The DP device is okay, but the conguration does not
correspond to the actual conguration of the device.
Compare the target conguration with the actual con‐
guration.
Note:
If the last slot is not assembled, you must mount the slot
cover! This is located in the termination module.
3 1: An external diagnostic function is
provided.
Evaluate the identier-related, the module status and/or
the channel-related diagnostics. As soon as all errors are
corrected, bit 3 is reset. The bit is reset when a new di‐
agnostic message is present in the bytes of the above-
mentioned diagnostics.
4 1: The requested function is not sup‐
ported by the DP device (e.g. chang‐
ing the PROFIBUS address via the
software).
Check the conguration.
5 1: The DP master cannot interpret
the response of the DP device.
Check the bus structure.
6 1: The DP parameter assignment
telegram is not correct (wrong de‐
vice type, parameter).
Correct the target and actual conguration.
7 1: The DP device has been parame‐
terized by another DP master (not by
the DP master that currently has ac‐
cess to the DP device).
The bit is always 1 if you are currently accessing the DP
device with the PG or another DP master, for example.
The PROFIBUS address of the DP master, which has par‐
ameterized the DP device, is included in the diagnostic
byte "Master PROFIBUS address".
Station status 2
Table 7-29 Setup of station status 2 (byte 1)
Bit Meaning
0 1: The DP device must be parameterized anew.
1 1: A diagnostic message is present. The DP device will not function until the error is eliminated
(static diagnostic message).
2 1: The bit is always "1" in the DP device.
3 1: Response monitoring is activated for this DP device.
