The status of points, especially proxy points, may explain what appears or does not appear as expected in a bound table or on a web chart. The following summarizes the meaning of each status and what, if anything, to do about it.
| Status | Description | Remedy |
|---|---|---|
| alarm | The point has a value in an alarm range as defined by a property in its alarm extension. | Acknowledge the alarm, investigate and fix the condition that caused the alarm. |
| down | Driver communication with the parent device as configured in the extension has been lost. All proxy point children of the device report a status of “down.” This status originates from a proxy point only. | Confirm that the parent device is on line and functioning correctly. |
| disabled | The proxy extension has been disabled. Polling stops for the point. This status originates from a proxy point only. | Enable the proxy extension. |
| fault | Typically, this indicates a configuration or license error. If a fault occurs following normal {ok} status, it could be a condition detected within the device, or perhaps some other fault criterion that was met. | Check the point’s proxy extension’s Fault Cause text for more information. |
| null | Indicates no status is available. Algorithm blocks may return a value with a null status in some cases. | Check the point configuration. |
| ok | Indicates that the point is functioning as expected. No status flag(s) are set. | No action required. |
| overridden | The functioning of the point has been stopped usually by a hardware override switch. | Make a physical inspection to the device. |
| stale | Since the last poll update, the system has not updated the point’s value within the specified Stale Time of its Tuning Policy. This status originates from a proxy point only. | This status clears upon receipt of the next poll value. |
