5.3.3
Channel diagnostics
Function
Channel-related diagnostics provides information about channel faults in modules.
Channel faults are mapped as channel diagnostics data in IO diagnostics data records.
The data record is read with the "RDREC" instruction (SFB 52).
Structure of the diagnostics data records
The data records supported by the ET 200AL distributed I/O system are based on the
PROFINET IO standard - Application Layer Service definition V2.2.
You can download the standard on the Internet (
) from home page of
the PROFIBUS user organization free of charge.
Structure of the manufacturer-specific diagnostics data records
The structure of the diagnostics data records is differentiated by the BlockVersion. The
following BlockVersion applies to the IM 157-1 PN interface modules:

5.3.4
Invalid configuration states of ET 200AL on the PROFINET IO
Invalid configuration states
If the number of modules exceeds the maximum configuration limit, the extra modules are
ignored by the system. No data exchange takes place.
5.3.5
STOP of the IO controller and recovery of the IO device
STOP of the SIMATIC IO controller
If diagnostics from the IO device are received by the IO controller in the STOP state, these
diagnostics do not result in a start of the organization blocks after startup of the IO controller.
You must read the data record E00C
H
in OB 100 with the "RDREC" instruction.
Return of the SIMATIC IO device
If you want to read out the diagnostics of a station after the station return, you must read the
data record E00C
H
in OB 86 with the "RDREC" instruction.
