Data Gap

Event name	Data gap
Meaning	The RMS server tries to read out (backfill) data from device after recovering from communication interruption. But the backfilling is not successful.
Case 1	Behavior	Three "Read out data" trials with the "Timeout" message. Afterwards the "Data gap" event occurs
Possible root cause	A communication problem between the device and the server during "read out data": 1) Faulty power supply 2) A network issue 3) A gateway issue
Action	Check the device status and make sure it is not in the "Device timeout" status. Retry to read out data manually: "Event page" > "Data gap event" > "Try again"
Case 2	Behavior	The "Read out data" trial with "No data" message followed by a "Data gap" event.
Possible root cause	The device has no measured data for the asked time period: 1) Faulty power supply (Battery, external supply, PoE) 2) The device was switched off 3) There was a deviation of the time synchronization
Action	1) Check in the audit trail for related information such as "Measuring time not valid" during the period of the data gap 2) Check in the IT system, whether the server time made a big jump
