TwinCAT,Codesys ; UDP Network Variables

[rahulnshinde]

Hi,
Greetings,
In one of my applications I need to create a network variable connection using UDP between a codesys target and Twincat controller.

Can anyone suggest how to proceed for the same?
If someone could post a sample project, it would be really helpful.

Regards,
Rahul.

On the TwinCAT Side, you will need the TCP Server Supplement Software...

The documentation is available here...

There are example programs for UDP here...

On the CoDeSys side, I think TCP and UDP depend on the vendor, what version are you using, and from what vendor?
