Associated with: WITS Outstations
Security permission required to access this pick action: Off/On Scan
You can use the On Scan action to set a Field Device that is currently 'off scan' back to 'on scan'. When a Field Device is 'on scan':
- The Field Device will log periodic data, log events, and generate DNP3 events for its points.
- The Field Device will set the ONLINE object flag for each of its points. For each point, it will also perform any action for ONLINE flag changes (see DNP3 Object Flag Actions).
- Any individual points that are set to 'off scan' will remain 'off scan'.
- Output points can be controlled.
Typically, you would use the On Scan action on an Outstation when the configuration for a Field Device is complete, and you want ClearSCADA to start retrieving its point data.
