Hello,
I am also currently researching the topic of communication between s7-1200 and ref615, can I contact you to discuss this issue?

Thank you.

I apology for that, 

I am currently a student at Ho Chi Minh city University of Technology, and I am researching communication between the S7-1200 and ABB REF615 relay as a basis for my thesis about adaptive protection in power grids using optimization algorithms and the application of the algorithm in practice.

I look forward to exchanging ideas and learning from everyone. Feel free to reach out to me [...]
Sincerely grateful.
