Automation Professionals is pleased to announce a BETA release of this Advanced Modbus driver module, with one bugfix and two features.

For Ignition v8.1+: ~~v1.1.10.243132114~~

- Fixed a bug in diagnostics that breaks device diagnostics for **all** devices in the gateway--that page then looks like no devices are configured. Due to `RateStats` losing its `Comparable<>` interface somewhere along the way. (And me not noticing.)

- Added `[Diagnostics]` folder to OPC browsing--basically a port of the code from the EtherNet/IP driver's `Driver` implementation. While in that mess, added separate diagnostic booleans for `ConnectedA` and `ConnectedB` when using live redundant connections.

- Altered the OPC browse to fan out the tree of OPC Item Paths in smaller increments, to dramatically reduce the amount of scrolling needed to browse to specific points.

The bugfix has been cooking for a couple weeks, so that is solid, but the new diagnostics are only lightly tested, and the new OPC fanout is _barely_ tested.
