Enabling the diagnostic interrupts
You enable the diagnostic interrupts in the basic parameters of the device configuration.
The technology module can trigger the following diagnostic interrupts:
Table 5- 5 Possible diagnostic interrupts
Diagnostic interrupt

•
Watchdog tripped. Module is defective.
•
Wire break at digital input A, B or N
•

Monitoring
Monitoring is always active. A diagnostic interrupt is
triggered each time an error is detected.
Monitoring is active if a push-pull switching encoder
has been configured. A detected error only triggers a
diagnostic interrupt if "Enable diagnostic interrupt for
wire break" has been enabled in the device configura-
tion.
Monitoring is always active. A detected error only
triggers a diagnostic interrupt if "Enable additional
diagnostic interrupts" has been enabled in the device
configuration.
