I’m trying to read a specific subset of analog points on multiple EB2s. i.e., I need to read all tank volumes (two on each EB), in the form “C0nn_TANKn”. The tank volume get read at different time intervals than say the wellhead pressures. See the flows below
Currently the SNAP PAC Read node only reads an individual point (tag, or table) or all points. So currently I read all the analog (or digital) points, and split out the specific point using SQL before pushing them into a MySQL database. The problem I run into is trying to read all the tags with multiple flows is random read errors.
What I’d like to see in a future release is the ability to read points or tags based on a search pattern, i.e. “C0%%_TANK%”
