Very solid explanation of DNP3 protocol. Far better than most other vides. Great job! Thank you!

[ScadaHub]

Your explanation is excellent. Perhaps you could enhance it by incorporating a demonstration using SCADA software, making it even more practical.👍

[sierossafaar]

Thanks for making it simple and clear! Is there a way to convert Modbus output to DNP3 without hardware modules?

[Anna-hfpv]

Are there examples of when Modbus would actually be more preferred? Are there any examples of data that don't necessarily need to be able to send alarm detections back to the master?

[baker]

thans for info. but you didn't mentioned the buffering of data and the time stamped which the protocol of DNP3 support

[msz]

Is there a way to secure DNP Protocol !!

I think client and server is more appropriate than master abd slave. Remember that this architecture dates since last century.
