– IEC 61850 startup log:
If feature is enabled a detailed log of the IEC 61850 connections will be dumped to the internal
file system of the RTU
This logging functionality is helpful to handle startup and failure diagnostic for resolving Point to
Point Protocol issues. Two ring buffered logfiles are created: syslog and syslog.0 (each limited
to 256 KB). The PPP events logged to these files may be analyzed for failed negotioations be-
tween RTU and the other peers e.g. because of wrong password or other parameters.
– VPN/E1/E2 logging:
These options offer the functionality to capture packets on network interfaces between RTU
and remote destinations. All packets sent or received on the interfaces E1, E2 or VPN via PPP
are written to a pcap compatible file. That created file can be loaded into Wireshark, which in
turn allows analysis of the stream(s) sent and received on the monitored network interface. For
VPN this functionality is helpful to analyze failed IKE negotiations.
The developer debug interfaces shall only be activated on special request.
For support cases a system information file can be downloaded to a PC. This file is used by the
RTU support line to analyze the status of this RTU. The file includes all information visible in the Web
server in a condensed form and the generated PPP/VPN/E1/E2 debug output, so that the user can
investigate anomalous behavior during initialization and running of PPP/VPN connections between
RTU and remote peer.
