You can start and stop SAC from running using the Stop and Start toggle button on the SAC tab of Mission Control. The Status field indicates if SAC is running or stopped. All other fields are used internally by Technical Support for debugging purposes.
The fields on the SAC tabbed page are as follows:
| Field | Description |
|---|---|
| Flag Count | Unused reserve counter. |
| Cycles/Sec | Average number of intervals that SAC has processed blocks in each second. |
| Percent | Maximum amount of CPU that SAC is allowed to consume during the interval. |
| Alm Priority | SAC will generate alarm only if the tag priority is equal to or higher than the specified value. Valid priority levels are CRITICAL, HIHI, HIGH, MEDIUM, LOW, LOLO and INFO. |
| Cycles/Min | Average number of intervals that SAC has processed blocks in each minute. |
| Duration | Amount of time consumed during the latest sampled interval. |
| Output | SAC will output value to I/O driver only if output is enabled. |
| Blocks/Sec | Average number of blocks SAC has processed per second. |
| Average | Average amount of time consumed during all intervals. |
| Missed Cycles | Number of times SAC was unable to process all blocks in the expected interval. |
| Blocks Proc. | Total number of blocks SAC has processed. |
| Max time | Maximum duration among sampled interval. |
| Status | The current state of SAC. Possible values are STOPPED, START and RUN. |
| % SAC Used |
Percentage of the total available SAC processing that was used in the last sample interval. This value is a result of the following calculation (involving the SAC counters A_SACCTL, A_SACINT AND A_SACPCT): % SAC Used = 100 - ( ( Fix32.FIXSCADA.SYSTEM.A_SACCTL * 500 ) / ( Fix32.FIXSCADA.SYSTEM.A_SACINT ) ) / ( Fix32.FIXSCADA.SYSTEM.A_SACPCT ) |
