6.1 Diagnostics Overview
The bridge contains software tools for diagnosing communication problems on
both the Ethernet and Modbus Plus network. Here is how you can approach a
suspected problem to localize it to one of the network interfaces.
6.1.1 Logging the Bridge’s Activity
Before running diagnostics you can log the communication activity in the bridge.
This can help you to determine the kind of diagnostics you may want to run.
Logging is detailed in Section 6.2.
6.1.2 Ethernet Diagnostics
First determine if the bridge can be recognized by your Ethernet host.
TCPINFO
If you have a BOOTP server and cannot access the bridge from it, run the
diagnostic TCPINFO in the bridge and try to access the bridge again.
You can start PING through a keyboard and monitor connected to the bridge.
After about 30 seconds, TCPINFO should report whether the bridge can be
configured by BOOTP.
TCPINFO is detailed in Section 6.3.
PING
The bridge has the PING utility program which you can use to check Ethernet
connections between the bridge and other IP addresses.
You can start PING from your Ethernet host, or you can start it locally through a
keyboard and monitor connected to the bridge.
PING is detailed in Section 6.5.
