Hi,
I want to use 4diac http on linux(ubuntu). For this I compiled forte with FORTE_COM_HTTP.
I used pthon server example like this:
pthon3 http.server 80 -> this provides a http server on localhost

Then I tried to use client_1 and also client_2_1 fbds, there is no connection to socket.
There is an error occures:
ERROR: A client should ALWAYS have exactly 2 RD ...

I added screentshots.
What am i missing?

Best regards

Hi,

as the error messages says you need a CLIENT FB with two RDs (outputs). This for example a CLIENT_1_2 or a CLIENT_0_3. You can create these by copying an existing CLIENT FB and adjust the name as well as the interface in the FB editor. You do not need to generate C++ code for these FBs.
I hope this helps.
