So I think I can run a MSG to read those tags every 200ms, 20ms might be a challenge
If you have the budget and a reason to use it, the 1756-RIO module has a "ghost mode" that allows it to listen to RIO I/O and Block Transfers without affecting the scantime or addressing of a RIO network.
This isn't the original multipurpose 1756-DHRIO; the 1756-RIO is an A-B Remote I/O scanning engine based on hardware and firmware built by QTS in Florida. Its network-based cousin the "AN-X" is distributed and supported through ProSoft, and has similar features available.
