Mapping to Alert Condition

Impacts Integrity?

Non-critical Mismatch Between Main Processor Data

The main processors have determined a mismatch in dynamic data other than outputs and secure parameter values.

ADVISE_ALERTS Non-critical Mismatch Between Main Processor Data

Y

Modules Not Executing at Configured Scan Rate

The logic solver has set the actual scan rate longer than the configured scan rate based on the estimate of execution time at download.

MAINT_ALERTS Modules Not Executing at Configured Scan Rate

 Y

Error on Non-Volatile Memory Restore

Main Processor 1 was not able to restore saved parameter records after a powerup or restart and has initialized non-volatile memory. The card is in an unconfigured state. The error is cleared on the next download or reset.

MAINT_ALERTS Non-Volatile Memory Battery or Chip Failure

Y

Less Than 5 Percent Parameter Records Available

Non-volatile memory availability to store parameter change records is low.

ADVISE_ALERTS Non-volatile Memory Alert

Y

Cyclic Redundancy Check Error on Non-Volatile Memory 

A CRC error occurred when writing a parameter record or during periodic check

MAINT_ALERTS Non-Volatile Memory Battery or Chip Failure

Y

Control Event Lost

A control event was not communicated to the controller because the buffer was full.

None

N

All Non-Volatile Memory Parameter Records Exhausted 

No more non-volatile memory is available for parameter change records

ADVISE_ALERTS Non-volatile Memory Alert

Y

Proof Test Reminder is Active

The logic solver proof test timer is within the reminder period of the required interval. 

ADVISE_ALERTS Proof Test Reminder is Active

N

Proof Test is Overdue

The logic solver proof test timer has exceeded the required interval.

ADVISE_ALERTS Proof Test is Overdue

N
