Archive Mask and Select Archives – How are they related?

[Andi]

Hello Mikhail,

while working on my Rapid SCADA project I noticed something that I do not fully understand regarding channel archives.

Every channel contains an Archive Mask value (for example 17 or 81) and there is also a Select Archives button.

However, when I click the Select Archives button, the dialog always opens with:

-Decimal value = 0
-all archive bits cleared

This happens even for channels whose Archive Mask column already contains values such as 17 or 81.

Nevertheless, the historical values are correctly written into PostgreSQL by ModArcPostgreSql, and Grafana displays them without any problem.

Therefore I would like to understand:

1. What is the difference between Archive Mask and Select Archives?

2. Which setting actually controls whether a channel is archived by ModArcPostgreSql?

3. Is it expected that the Select Archives dialog opens with all bits cleared although the channel table already contains Archive Mask values?

Thank you very much for your help!
