Table 7-49 Conguration from byte x+4 for update interrupt
Byte 7 6 5 4 3 2 1 0 Description
Byte x+4 Data record index: Is the number of the parameter assign‐
ment data record that led to the update interrupt.
Byte x+5 Number of updates that could not be reported to the CPU.
7.13.15 Diagnostics for incorrect conguration states of the ET 200iSP with PROFIBUS
Incorrect conguration states
The following incorrect expansion states of the ET 200iSP lead to a station failure of theET 200iSP
or prevent entry into the data exchange. These reactions are independent of the release of the
interface module parameter "Operation at setpoint <> actual conguration":
• Two missing electronic modules
• Terminating module missing
• Number of modules exceeds maximum conguration
• Faulty backplane bus (e.g. defective terminal module)
Note
If a module is missing (gap) and the ET 200iSP POWER OFF/POWER ON is switched, then the
ET 200iSP starts. The startup with more than one missing module is not possible. If more than
one electronic module is missing, then after plugging in these modules a safe start-up of the
ET 200iSP is only guaranteed after POWER OFF/ POWER ON.
Diagnostics for PROFIBUS
You can recognize all incorrect conguration states by the following diagnosis:
Table 7-50 Diagnostics for incorrect conguration states of the ET 200iSP
Identier-related diagnostics: Module status
All bits from slot 4 to 35 are set 01
B
: "Module error, invalid payload" up to the slot of
the cause of failure
11
B
: "No module; invalid payload" from the slot of
the cause of failure
