 Store data from an OPC server to a database based on a trigger value

Problem

I'm looking at the OPC Data Logger. One feature I'm looking for is if it will store data from an OPC server to a database based on a trigger value.


Solution

The enterprise version of our software has many filter plugins. For simple tasks you can use the Expressions plugin. Foe example, the following expression will not allow to write to a database, if Avalue isn't equal to 5.

DISCARD_DATA_PACKET_IF(AValue<>5)
