Hi Lucas,
Thanks for reaching out!
To answer your question, our course developers are certainly working on a course on DCS. I am not sure, when exactly this would go live, but this is certainly coming in the near future!
Regarding safety PLC's, this is a great topic suggestion! I have forwarded this to our creator team, right away. Hopefully, they are able to add this to the list. Thanks a lot for sharing this with us, we always appreciate such suggestions.
Hopefully, this answers your question. If you have any other questions or would like any further assistance always feel free to reach out to me anytime!
Happy learning! :)
