Having to manually refresh tag browse for tags to show up with Siemens Enhanced Driver

Hi, I am using the Siemens enhanced driver with an S7-1500 PLC firmware V3.1.4, Ignition V8.3.2 and am experiencing an issue where when I add a new parameter to the PLC program (e.g. a new parameter in a datablock), the new parameter does not show up in the perspective tag browser until I manually refresh the tag browse at the gateway device connection.

I tried manually typing in the OPC tag path as well by copying an existing functional parameter in the same datablock but this also did not work until the manual refresh. Is this behavior known/expected? I saw another thread mention issues with the tag browse but my issue is different in that only the newly added tag does not work before refreshing, not all of my tags.

If this is expected, I will try to find a way to force a refresh via gateway script but would prefer to not need to do this.

Thank you in advance!

Expected and unfixable behavior. Unlike Rockwell's Logix processors, which expose metadata that signals tag edits, Siemens has no mechanism at all that IA (or anyone else) could use to automatically notice your new tags.

That's why there's a button in the UI to do a rebrowse.

IIRC, rebrowse does disrupt current tag ops, so you probably don't want to do this unnecessarily.

Dang okay that’s unfortunate. Thanks for confirming!
