"Logged Data" Message in "Display Alarms"

[abdullah123456789]

Hello,

I viewed the 'Display Alarms' list in Geo SCADA Expert 2021. In the list I saw 'Logged data' message more than one as in the screenshot. When the message contained 'Logged data' instead of 'Current data', I've changed 'Fullscale' values in this situation. So the message disappeared. But if the message contains 'Logged data', the alarm doesn't go away. What could be the cause of this problem and how could i solve this?

I do not use a lot of analog alarms and I am bit rusty on when they update for alarm changes but generally the value has to change before it clears. It may need to go below the original value it alarmed on before clearing.

If you are not otherwise using the analog alarms on these points you can just right click on the alarm and select remove to get it out of the list. It will technically still be in the alarm State until the logged data value changes to an appropriate value.

You can also set Overrange to be an event or set it to none if an Overrange is not something you want to alarm on.

The meaning of "Current Data" and "Logged Data" depends on which driver/protocol you're using. For example, in DNP3 current data is 'static data' and logged data is 'event data'. Which driver are you using?

An analog point overactive alarm should clear once the value of the point drops below the full scale of the point regardless of whether alarm was raised from current data or logged data.
