Simple Network Published Variable help

[RTSLVU]

I am writing a program to be a "LabView wrapper" for iperf 

I need to run iperf server and iperf client on two different machines.

Machine A: Launch iperf server and write ture to a shared variable

Machine B: Read shared variable and launch iperf client if machine A is running iperf server

I have never used a shared variable before, I have looked at the examples but as usual they work but are lacking and explanation as to why or how.

I have managed to get as far as creating a shard variable as a network published type Boolean Putting a shared variable on my block diagram I can select the server variable from my project just fine but the shared variable is read only? 

How do I write to a shared variable?
