Use the fields within the Communication Statistic Updates section of the tab to define how often the communication statistics are updated for the VT Port. You can view the statistics on the port’s Status display.
- Interval—Use to specify the frequency at which the VT Port’s communications statistics are updated. Enter the frequency in the OPC Time Format, for example, 1M (for one minute), or specify 0 to disable the Communications Statistics feature.
- Offset—Use to specify the offset, from midnight, for the first communications statistics update. Thereafter, the statistics are updated at the frequency specified in the Interval field, above.
- Enter the offset in the OPC Time Format, for example 30S (for a 30-second offset).
With either field, you can enter the required value directly in the field, or use the Interval Window (accessed via each field’s browse button) to specify the required interval or offset.
Example:
The Communication Statistic Updates settings for a VT Service Port Master are configured as:
Interval: 1M
Offset: 30S
If the time is currently 00:00:00, the next Communications Statistics update will occur at 00:00:30, followed by another update at 00:01:30, then another update at 00:02:30, and so on, at 1-minute intervals offset to 30-seconds past each minute.
