3. Evaluate the diagnostic message:
Result:
– Station status 1 (byte 0): Bit 3 is set -> External diagnostics
– ID-related diagnostics: Bit 3 in byte 7 is set -> slot 4
– Module status: Byte 16.7 / 16.6: 11
B
-> no module
4. Re-insert the unplugged electronics module in the terminal module.
Result:
– Status LEDs IM 152:
SF: off
BF: off
ON: lit
PS ON: lit
– The diagnostic message is deleted.

Wire break of NAMUR encoder on digital input module
Procedure
1. Remove the wire from terminal 1 of the first 8 DI NAMUR electronic module.
2. Observe the status LEDs.
– Status LED IM 152:
SF: on -> diagnostic message exists
– Status LEDs electronic module 8 DI NAMUR:
SF: on -> diagnostic message exists
3: off/on
3. Evaluate the diagnostic message
Result:
– Station status 1 (byte 0): Bit 3 is set -> External diagnostics
– ID-related diagnostics: Byte 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
4. Connect the wire to the BERO again in terminal 1 and evaluate the diagnostics again:
– Status LED IM 152
SF: off
– Status LEDs electronic module 8 DI NAMUR:
SF: off
3: off/on
– The diagnostic message is deleted.
