Communication with Arduino Ethernet Shield

Hi all,

I want to establish communication between Flexsim and Arduino Ethernet Shield, where Flexsim is ''client''. I want to test the communication with a simple system but I failed (normally if it works, an LED will light at arrival of the box).

You can see my system on attached file

You will see my script at opening, but don't forget, please, to open the Photo Eye proprieties and see what I put on ''On Block'' and ''On clear''.

"var1" is a Global Variable.

Thank you, all.
