CSLS_NAME/ADVISE_ALERTS |
Advisory alert status of the CHARM smart logic solver, combination of both cards when redundant |
|
Condition Text in AdviseAlerts |
Meaning |
Action |
|---|---|---|
|
CHARMbus Termination Error |
CHARMbus terminator on the last LS CHARM baseplate is missing. |
If the condition persists, contact Emerson Technical Support. |
|
CHARMs subsystem Mismatch |
The configuration for one or more communicating LS CHARM does not match the physical LS CHARM. |
If the condition persists, contact Emerson Technical Support. |
|
Configuration Mismatch Between [CHARMs] Logic Solver and Controller |
The Controller detects a mismatch between the configured and reported DeviceCRC. |
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. |
|
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. |
|
High Railbus Error Rate |
The Main Processor 1 detects a high percentage error rate in communications with the Controller. |
Can be due to an environmental specification being exceeded. If the condition persists, contact Emerson Technical Support. |
|
High Redundancy Link Error Rate |
The Logic Solver detects a high percentage communications error rate on the redundancy link. |
Can be due to an environmental specification being exceeded. If the condition persists, contact Emerson Technical Support. |
|
I/O Processor Communication Error |
The Logic Solver detects a high percentage error rate in communications with the I/O Processor. |
Can be due to an environmental specification being exceeded. If the condition persists, contact Emerson Technical Support. |
|
I/O Processor Integrity Error |
The I/O Processor is reporting a calibration or self-test error. |
Check the value of IO_DEV_STATUS. A calibration issue requires a hardware return. If an incomplete self-test error persists, contact Emerson Technical Support. |
|
Internal Communications Error |
A high percentage error rate exists in communications between the main processors. |
Can be due to an environmental specification being exceeded. If the condition persists, contact Emerson Technical Support. |
|
Local Safety Net High Error Rate |
The total bit error rate on the controller interfaces exceeds 10-4. |
If the condition persists, contact Emerson Technical Support. |
|
Non-Critical Mismatch Between Main Processor Data |
The main processors have detected 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. If the condition does not clear, contact Emerson Technical Support. |
|
Non-Volatile Memory Alert |
The Non-Volatile Memory (NVM) available for parameter change records is low or exhausted. |
Use DeltaV Explorer to upload recorded parameter changes for the logic solver, then re-download. |
|
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. |
|
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. |
|
Self-Test Incomplete |
A periodic memory test failed to 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. If the condition persists or repeats, contact Emerson Technical Support. |
|
SIS Communications High Error Rate |
For CHARMs Smart Logic Solvers, the total bit error rate on local peer communication interfaces has exceeded 10-4. |
If the condition persists, contact Emerson Technical Support. |
|
SISNet High Error Rate |
The Main Processor 1 or Main Processor 2 has detected a high peer bus error rate. |
Can be due to an environmental specification being exceeded. If the condition persists, contact Emerson Technical Support. |
|
Task Checkpoint Alarm |
A non-critical task has not completed properly in one of the subsystems. |
If the condition repeats, contact Emerson Technical Support. |
