Need to build communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer

Hi - I would like to build the logic in which it should accomodate the communication redundancy using serial RS-232 for Data Transfer b/w Host and RT irrespective of TCP/IP Data Transfer.

 

I want to do data transfer b/w host and RT through RS232 VISA portal whenever TCP/IP ethernet cable has been unplugged from the controller continuosly , it should keep on checking for TCP/IP link re-establishing also , when ever the tcp/ip link established again that time the communication should be using in that link only. This is accomplished by deploying the RT vi as execuatbale file. I made some logic regards to the above said logic , bur it was not working as much I expected.

 

I request you to go through the attached two VI's and let me know , what I did wrong in that,

 

Please do the needful.
