BadFilterNotAllowed subscribing to a boolean

Hi, your UA server is returning BadFilterNotAllowed when I am subscribing to a boolean.

The issue seems to be around the deadband (I’m guessing the subscription is sending a zero)

I’ve told OPLCLabs about it here … -a-boolean

but I am wondering if anything can be done about it your end.

(I assume this problem is just with your server)

I think you’ll need to create the monitored item using a different change filter (or none at all). You’re probably trying to use a deadband, which isn’t allowed on non-numeric types.
