The "Diag.ext_fault“ bit (bit 3 in octet 1) is always set in the event of external diagnostics. Octets 7 and 8 are normally only transferred
when this bit is set.
**
Octets 7 and 8 are always transferred in the case of the DP/3WN1, 3WS1 interface, even if the "Diag.ext_fault“ bit (bit 3 in octet 1)
has not been set, i.e. if no external diagnostics are active.
Note: Octet 8 is different in interfaces DP/3WN6 and DP/3WN1, 3WS1. See page 60 for details.
4.6 Displaying the data in the 3WN1/3WS1 circuit-breaker
After the interface module has been parameterized and configured by the master, the two stations can start
the data exchange cycle (= normal operating state).
If diagnostic data or faults occur in the interface module, the master is informed about the presence of this
signal by means of a high-priority data message.
