4. Analyze the diagnostic message.
Result for PROFINET conguration:
– Identier-related diagnostics: Bit 7.3 is set -> Slot 2
– Slot: 2
Subslot: 1
Channel fault type: 6 - Wire break
Result for PROFIBUS conguration:
– Station status 1 (byte 0): Bit 3 is set -> External diagnostics
– Identier-related diagnostics: Bit 7.3 is set -> Slot 4
– Channel-related diagnostics:
Byte 25: 10000011
B
-> Slot 4
Byte 26: 01000000
B
-> Channel 0
Byte 27: 00110
B
-> Wire break
5. Connect the cable to the BERO back to terminal 1 and analyze the diagnostics again:
Result:
For PROFINET conguration - LEDs on the interface module IM 152-1PN of the ET 200iSP:
– ER: O
For PROFIBUS conguration - LEDs on the interface module IM 152-1DP of the ET 200iSP:
– SF: O
Status LEDs electronic module 8 DI NAMUR:
– SF: O
– 3: o/on
The diagnostic message has been deleted.
