Set up point polling
Polling proxy points on a regular basis, such as once per second, is one way of refreshing point values. A value is sent to
the station each time the device point is polled. Each device has its own polling schedule.
- To go to the property sheet for the device, double-click the device under the MercuryNetwork folder in the Nav tree, or right-click the device and click Views→Property Sheet.
- Expand Communicator and expand Poll Scheduler.
In the example above, Enabled set to true turns point polling on. The Slow Rate, set to once every second in this example, controls the polling rate.
NoteIf you are using polling for event notification, keep the poll rate low. Thirty (30) seconds is much too long for polling.
