Is anybody aware if device identification (see https://www.symantec.com/security_response/attacksignatures/detail.jsp?asid=20672) is a functionality available on RTU devices? Would it make sense to add this to the library?
DZG has an example that shows similar commands, see chapter 1.6.1 in https://www.dzg.de/fileadmin/dzg/content/downloads/produkte-zaehler/dvh4013/Communication-Protocol_DVH4013.pdf.
