I'm following the course from https://www.eclipse.org/4diac/en_help.php?helppage=html/4diacIDE/distribute4diac.html#SetUpCommunication
Now I set up the logic completely according to the process, but the data did not circulate successfully, please check attached pic shows
I want to setup data connection, but I'm not sure where my problem is, can you please suggest if I should have any more operations.

hi,
have you either manually inserted communication function blocks into your resources or created the communication function blocks with our experimental generation facility?

Unfortunately there is an issue with the console. Therefore you currently don't see any output there.

Cheers,
Alois

Do you mean Publish and Subscribe node?
I add them in my logic, but I don't see data communicate between them

Your publisher is missing a data connection. Therefore it reports to you a data type error as values of type any can not be send.

Please also not that you don't need to have the publish and subscribe blocks on your application it is perfectly fine to have them in the resource.
