Condition Text in AdviseAlerts |
Meaning |
Action |
|---|---|---|
|
SISNet High Error Rate |
High peer bus error rate detected by MP1 or MP2. |
Can be due to an environmental specification being exceeded. Contact technical support if the condition persists. |
|
I/O Processor Communication Error |
MP2 sees a high percentage error rate in communications with the I/O processor. |
Can be due to an environmental specification being exceeded. Contact technical support if the condition persists. |
|
Non-volatile Memory Alert |
Non-volatile Memory availability for parameter change records is low or exhausted. |
Use DeltaV Explorer to upload recorded parameter changes for the logic solver, then re-download. |
|
High Railbus Error Rate |
MP1 sees a high percentage error rate in communications with the controller. |
Can be due to an environmental specification being exceeded. Contact technical support if the condition persists. |
|
High Redundancy Link Error Rate |
MP1 sees a high percentage communications error rate on the redundancy link. |
Can be due to an environmental specification being exceeded. Contact technical support if the condition persists. |
|
I/O Processor Integrity Error |
The I/O Processor is reporting a calibration or self-test error. |
Check the value of IO_DEV_STATUS. If an incomplete self-test error persists, contact tech support. A calibration issue requires a hardware return. |
|
Self-Test Incomplete |
A periodic memory test did not complete in the allotted time. |
Check the value of DIAG_STATUS and IO_DEV_STATUS to determine if the issue is with the main processors or I/O processor. Contact tech support if the issue persists or repeats. |
|
Configuration Mismatch Between Logic Solver and Controller |
Controller sees mismatch between configured and reported DEV_CRC. |
If redundant, do a switchover of the logic solver. If the condition does not clear or the logic solver is simplex, download the logic solver. |
|
Internal Communications Error |
There is a high percentage error rate in communications between the main processors. |
Can be due to an environmental specification being exceeded. Contact technical support if the condition persists. |
|
Non-Critical Mismatch Between Main Processor Data |
The main processors have determined a mismatch in dynamic data other than outputs and secure parameter values. |
The logic solver will still be able to respond to a demand if this condition is active. If the condition persists, do a switchover of the logic solver or download it. Contact technical support if the condition does not clear. |
|
Proof Test Reminder is Active |
The number of days since the last proof test is approaching the required proof test interval. |
If an automatic proof test has been configured, this alert indicates the test will begin in five minutes. Otherwise, a manual test should be scheduled. |
|
Proof Test is Overdue |
The number of days since the last proof test has exceeded the required proof test interval. |
Perform a manual proof test. |
|
CPU Free Time Low < 20% |
The idle time on one or both of the main processors is less than 20% of the total task time. |
Change to a slower logic solver scan rate and re-download. |
|
Task Checkpoint Alarm |
A non-critical task has not completed properly in one of the subsystems. |
Contact tech support if this condition repeats. |
