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
