This JKI RCF Plugin sets the Visible Frame property of a Case Structure while the owning VI is running. Use it to follow the execution through the cases in your string-based State Machine/Sequencer when Execution Highlighting isn't fast enough (and, it's never fast enough).

The use-case I wrote this to improve is setting a Breakpoint on the Error wire coming out of the main Case Structure and probing the Case Selector terminal so I can float-probe wires during execution. The problem with this is that I had to manually select the current frame every time. This is boring, so I developed this plugin to automatically set the Visible Frame to the case most recently executed.

Use - Select the String wire connected to the main Case Structure's selector terminal, invoke the JKI RCF and select StateFollower.

Special thanks to - AristosQueue, for his help over here.

LabVIEW versions - tested in 2009 & 2011 - it should work in 2010 as well

Installation - use VIPM to install the VI Package

I tried making this work in older versions, but the Attach Probe wire method didn't work in 8.2 or 8.6. If you believe I'm mistaken I'll take another crack at it.

Here's a demo VI with instructions to show what this plugin does.
