Errors from the bus/backplane bus
The transport layer of the bus system being used (backplane bus, PROFIBUS, PROFINET)
is signaling an error. For precise troubleshooting and analysis, a PROFIBUS tracer can be
useful. For PROFINET, the open source software "Wireshark" can be used. The PROFIBUS
or PROFINET system diagnostics can provide further information about the cause of the
error.
Error messages that start with "80/C0/DE/DF" relate to errors from the bus/backplane bus.
You will find details of the error message in the STEP 7 help on the blocks "WRREC" or
"RDREC" (SFB52/SFB53).
