AN-X displays the result of the configuration. The upper pane shows the configuration file it
downloaded. The lower pane shows the router configuration log. Always check the log after you
configure the router to ensure there were no errors.
The Router Configuration log is also available by selecting Automation Network/DH+ Router
View.
Log Files
AN-X maintains various logs to record diagnostic and error messages. Use the Log Files menu in
the web interface to view these logs.
In all cases except the Alias Log and the System Info logs, when the current log file becomes full,
AN-X renames it so you can access it as the previous log file.
Ethernet/IP Log
The Ethernet/IP Log shows messages and errors associated with Ethernet/IP and Data Highway
Plus operations that are initiated from Ethernet (base IP address).
Ethernet AB/CSP/HMI Log
The Ethernet AB/CSP/HMI Log displays messages and errors associated with AB Ethernet CSP
and Data Highway Plus operations that are initiated from Ethernet (aliased IP addresses).
DH+ Router Log
The DH+ Router Log displays runtime messages and errors associated with messages initiated
on Data Highway Plus and routed to Ethernet using the DH+ router function (Ethernet/IP or
CSP).
DH+ Traffic Logs
There are three logs that can be used to measure total Data Highway Plus network traffic and the
traffic on individual stations.
The logs are:
the Data Highway Plus Total Traffic Log
the Data Highway Plus Station Traffic Log
the Data Highway Plus Response Traffic Log
In each log, the percentages are the ratio of the number of bytes to the total bytes that could be
sent in the time period at the current baud rate.
The sum of the station percentages should be approximately equal to the total percent.
The numbers are based on 6 second samples.
DH+ Total Traffic Log
The DH+ Total Traffic Log shows the percentage of network time on the local DH+ being used
by all stations. It measures the overall loading of the network. The maximum possible loading is
about 75%. The rest of the network time is used for interpacket spacing, ACKs/NAKs, token
passing, and soliciting new stations coming online.
