To many tags

I have 1515 tags in my flexy split between two different IO servers. Both IO servers point to the same PLC. Maybe this doesn’t help or is not allowed. When I try to add the 1516th tag, I get a “too many tags error”. I thought the flexy could handle 2500 tags? Thoughts? Is there a way around this as I need 1600 tags.
Thanks!

Hello Bryan,

The Flexy supports overall 2500 Tags across all IO drivers, however, it only supports ~1500 tags from a single IO Driver.

Thank you
