Remote Diagnostics
An Ethernet CyScan system provides a remote diagnostics facility. The sensor autonomously emits diagnostic telegrams triggered by internal events and/or at configured periods.
Remote Diagnostic Protocol
The diagnostic telegram is of variable length, up to a maximum of 1000 characters. Its format is as follows:
\s:NNNNNNNNNN*KK\$PGNMD,T,YYYY˽YY˽YY,HH˽HH˽HH.HHH,[D]D=[V]V*CC<CR><LF>

The diagnostic telegrams are delivered by means of UDP/IP through the
same Ethernet port as the client data. If no event-triggered telegrams
are emitted during a period of time defaulting to 60 minutes, a General
Status telegram is emitted.
