I read in the PDF for network.lib that there should be some demo code for different cases, I would like to see the SMTP\_CLIENT\_DEMO, so far so good, but then it is written that the demo are hidden, and that is true because I cant find them for Codesys, I can find some code in the lib for pcworx but that code do not look to be compatible with Codesys?

My mail problem is how to login to the smtp server, where to put username and password.

Regards

open the network.lib in codesys as a projekt and look into the directory “demo”  
there are some sample modules
