Default diagnostics
The following values are decisive for the diagnostics:
Ext_Diag: Group signal for diagnostics in the slave:

- 0: No fault is active
- 1: At least one alarm or fault is active
Ext_Diag_Overflow:
•
Display for the diagnostics overflow in the slave (for more than 240 bytes)
Identifier-related diagnostics
The identifier-related diagnostics provides a bit (KB_n) for each slot allocated when configuring the
device. If a diagnostics message is active at a slot, then it's KB_n = 1.
For G120 only one slot is allocated:
KB_0 when configuring with the GSD
•
