9.6 RF Refresh Time Tag(s)
Adding an RF Refresh Time tag to any Modbus point ensures the data that is
held in the Modbus table is valid. When the RF Refresh tag is used for trending,
a normal graph will look like a sawtooth.
Since there are no RSSI tags available between Gateway to Gateway, adding a
RF refresh time tag to any of the shared points (peer-to-peer) can be very
valuable.
1. Double-click on Gateway in project tree.
2. Click on the Modbus tab
3. Right-click on a point and select Add Refresh Time .
4. Save the project file and update the impacted devices.
5. Poll Modbus register to verify refresh count.
i. Refresh count moves in 1 second increments.
Example: If tx interval is 60 seconds, the RF refresh count will
update in increments of 60.
