Reactions to a diagnostic alarm in DPV1 mode, depending on parameter settings
Actions initiated by diagnostic alarms:
●
The diagnostics are reported as diagnostic interrupts.
●
In DPV1 mode, diagnostic information is also reported when the CPU is in STOP mode.
●
Once a diagnostic alarm is signaled it is
–
Entered in the diagnostic frame as a diagnostic block (one interrupt only)
–
Stored in the diagnostic buffer of the CPU
–
Entered in the channel-specific diagnostic data
●
The SF LED of the interface module and, if applicable, on the affected electronic module
is lit.
●
OB 82 is called. If OB 82 is not available, the CPU goes to STOP.
●
Acknowledgment of the diagnostic interrupt The enables a new interrupt.
Reactions to a diagnostic alarm in DPV0 mode, depending on parameter settings
The error is entered in the channel-specific diagnostic information in the diagnostic frame:
●
The SF LED of the interface module and, if applicable, on the affected electronic module
is lit.
●
There can be more than one diagnostic alarm at a given time.
