C# app passing variable to Q03UDE??

Hello again good people of the forum,

Today's challenge should you choose to accept it, is to explain to me the best/easiest way to send a variable to from a C# windows app to a Q series over ethernet!?

All samples, drivers, advice welcome!!

Thanks

AdvancedHMI using ModbusTCP would probably work for you. Ingear also sells a ModbusTCP driver DLL that you can use native in your code if you already have an application made.
