Some Information About This Site

This site is maintained by CDOAN, which is actually just an individual. Someone of you may know me. My name is Jack Verson, I have been in the SCADA industry since the mid-1970s, and am now retired. However, we retired people need to keep busy, so, in order for me to keep busy, I have designed and written three products:

  • DNP3 Communication Test Tool

  • DNP3 Outstation Source Code Library

  • IEC 60870-5-101/104 Communication Test Tool

I also have a 13-lesson tutorial on DNP3 protocol, available YouTube (search for "DNP3 Basics"). 

All products and lessons are FREE

For the products, you need to send in a request for a license, but there is no charge for one. 

In addition to the products I have written and released, I also offer consulting on DNP3 protocol. I have been on the DNP3 Technical Committee since inception. I am also familiar with about 100 legacy protocols of which most of you have never heard. So, if you have a question, feel free to send it in to cdoancal@gmail.com. Again, no charge, unless the questions get complicated and time consuming. In that case, we can talk more about some payment. (I cannot offer support on secure authentication.)
