9.2.5
Channel diagnostics
The PROFINET interfaces of the IM 153-4 PN support the diagnostics concept and
maintenance concept in PROFINET IO in accordance with the standard IEC61158-6-10.
Diagnostic interrupts use the channel-specific diagnosis according to IEC 61158-6 as
interrupt information.
PROFINET IO also permits the reading of diagnostic states via standardized data records.
For example, the diagnostic state of a module can be read using the data record C00A hex.
The data record is read by calling SFB 52 RDREC (read data record).
9.2.6
Error types for modules
For detailed information about the error types for modules of the ET 200M, refer to chapter
"Identifier-related diagnosis (Page 198)".
9.2.7
Diagnostics of incorrect configuration states of ET 200M on PROFINET IO
Incorrect module configuration states
The following incorrect ET 200M configuration states lead to a failure of the ET 200M I/O
device or prevent data exchange:
●
Number of modules exceeds maximum configuration
●
Faulty backplane bus, for example, defective active bus module
9.2.8
Diagnostics events triggered by a STOP of the I/O controller
If communication diagnostics of the PROFINET interface ports is triggered when the IO
controller is in STOP state, these diagnostics will not be signaled after startup of the IO
controller.
