Associated with: EcoStruxure Web Services scanners
The Error Statistics attribute shows the number of errors generated during any of the read or write operations that are summarized by the Comms Statistics attribute.
The Error Statistics indicate the number of occurrences of each of the following since the scanner was last restarted:
- Read Errors—The number of errors generated when attempting to read items. For example, if the Simple EcoStruxure Web Services Client Driver issues a read for the item, but the target EcoStruxure Web Services server returns an error.
- Write Errors—The number of errors reported from write operations.
- Unknown Item Errors—The number of write completion messages that have been received for ‘unknown’ controls (controls that have not been sent by the Geo SCADA Expert server).
-
Example:
2 read errors, 2 write errors, 0 unknown item errors
