I'm building a Mango website to monitor some power meter via Ethenet. Below is my data point logging setting.
Today, my server disconnect or the meter disconnect, the server keeps logging last data value (see photo below)
From 3PM to 9PM, the server is disconnected so I expect the value should be 0.
Is there are any setting so I can make sure the logging value is 0 if server/power meter disconnected, therefore I or anyone can realize the abnormal and check the server/meter?
