Data source tag: Event settings

The page displays the events associated with the selected tag or group of tags in tabular form..

• "New Event" button - opens a dialog for creating a new event.
• Link to the "Event Text" field opens dialog for editing this event.
• Link to the "Tag Name" field will select the appropriate tag in the tag tree list (and filtering for the "Event Setup" tab will be performed by the selected tag).
• The icon "" allows you to delete the configured event.
• The buttons at the top of the table allow you to display all elements of the table at once, or export the table to a file.

Editing an event

The event edit page allows you to define the conditions of the event occurrence and disappearance of the event and the attributes of the event itself.

• In the Tag Name field, a tag name must be selected. It may be pre-selected if this form call occurred with a single tag selected in the tree view, or it may contain a list of tags if a node with a group of tags was pre-selected.
• The Event ON when and Event OFF when - drop-down lists with boolean operations and direct value entry fields define the conditions against which each incoming value of that tag from the data source will be compared. A new entry will be added to the event log if no such event has previously been started. The "ON time" will be specified as the time when the value of this tag was recorded by the data source. The event is now considered active (or "live"). If this event is active, and new value comes that satisfies the condition set in "Event OFF when", the event record is updated - the time of leaving is recorded for the record and the event is no longer considered active. If a tag with command is selected, the data source sends a single event with the result of the command. In this case it is possible to specify only and "EAST condition" and select possible option - "when command is executed", "when command is executed successfully" or "when command is executed with error".
• In the field Event text you can write the text that will be displayed in the event log. Variables, {tag_text} - tag name or {tagvalue} - tag value at the time the event occurred, can be substituted in the field. The event can be defined for a tag with a command, in which case the variable {cmdresult} - which will be replaced by `success or Error` in the event text. If no event text is specified, the default system text will be used.
• Event Level - In the event log the event record will be marked with colour depending on the level (significance). Possible variations
  • System event
  • Event (normal)
  • Warning
  • Failure
  • Critical

Event acknowledgement required - The event can be configured to be acknowledged by the user in an "operational mode". In this case, if such previously recorded event is not already active and not yet acknowledged by operator, then when a condition of such event occurs, new event is not added by new line in log, but counter of the current event (unconfirmed, in existing line) will be incremented. The log may display a circle with a number next to the event name - the number of appearances (and disappearances) of the event since the last confirmation.

Updates to the event configuration are picked up by the data source on subsequent connection or automatically within 1 minute.
