DNP3 Serial Protocol Support

Is DNP3 Serial a supported protocol?

[#2 · Accepted solution]

Hi @ry_panov, DNP3 is supported however there is no means to get the data from the serial line itself. If the engineering workstation sends commands through the network to a PLC that is connected via serial to that device then DIoT will "see" that device and any communication that is sourced from that device to the network. Note that with these types of questions, the core functionality of DIoT is to protect the OT network and if a device has zero means to talk on the network then it is not a risk to the network.
