5.3.2.5
STOP of the IO controller and recovery of the IO device
STOP of IO controller
The PN/MF Coupler indicates the STOP state of the IO controller of the other bus side using
the optional "Data validity" diagnostics.
Diagnostics after STOP of the IO controller
If diagnostics are received from the IO device while the IO controller is in STOP state, the
corresponding organization blocks are not initiated after startup of the IO controller. You
must get an idea of the state of the IO device in OB 100. Evaluate the data status byte (DS) of
the input modules in your user program.
Diagnostics after recovery of the IO device
Following recovery of an IO device, you must read data record E00C
instruction. This contains all the diagnostics data for the slots assigned to an IO controller in
an IO device.
5.3.3
Reading service data
Service data
Service data for the PN/MF Coupler include:
• Fatal error information
• Device trace for X1 and X2 interface
• Device memory statistics
These are all cases where you can call Siemens Industry Online Support for help. Only
Siemens Industry Online Support can evaluate this binary file.
STEP 7 V5.6 or higher
You can load the service data in STEP 7 as of V5.6 HF3. The service data is only available via
the "Accessible devices".
