Due to the switch by internet providers to new encryption standards (TLS 1.1 and 1.2) for email communication, sending emails no longer worked in many older WinCC projects. The solution is to replace the existing, older CDO.Message module CDOSYS (Collaboration Data Objects for Windows 2000). This was implemented using a new COM object, which is integrated into WinCC via Visual Basic.
Goal:
- Email sending with current encryption using WinCC
- Reusable module as a COM object
- Continue use of existing WinCC projects

Implemented solution:
- Integrated into WinCC
- Using standard libraries (System.Net.Mail and libcurl/smtp)
- Integration via ANSI C or VB from WinCC
