There are 11 alarms provided by the module templates. All alarms are disabled by default except the PVBAD_ALM. The alarm limits and priorities can be modified, and alarms can be enabled or disabled individually in either the AI Block (RMT_SPM_HART) or the Alarm Block (RMT_SPM_FF). Default alarm limits, priorities, and enabled states are shown below.
| Alarm | Parameter | Limit Value | Enabled | Priority |
|---|---|---|---|---|
| CV_HI | CV/HI_ACT | 1 | False | Advisory |
| CV_LO | CV/LO_ACT | 0 | False | Advisory |
| HI_ALM | AI1/HI_ACT | 95 | False | Warning |
| HI_HI_ALM | AI1/HI_HI_ACT | 100 | False | Critical |
| LO_ALM | AI1/LO_ACT | 5 | False | Warning |
| LO_LO_ALM | AI1/LO_LO_ACT | 0 | False | Critical |
| MEAN_HI | MEAN/HI_ACT | 95 | False | Log |
| MEAN_LO | MEAN/LO_ACT | 5 | False | Log |
| PVBAD_ALM | AI1/BAD_ACTIVE | --- | True | Critical |
| STDEV_HI | STDEV/HI_ACT | 1 | False | Advisory |
| STDEV_LO | STDEV/LO_ACT | 0 | False | Advisory |
Typically alarms are left disabled and the SPM data is logged into the process historian for a period of time. Alarm limits are adjusted, and alarms are enabled, after operating experience determines the threshold of transition from normal to abnormal process conditions.
