6.1.3 Modbus Plus Diagnostics
If you can communicate with the bridge from your Ethernet host, but cannot pass
messages to Modbus Plus nodes, you can test the bridge’s communication on
Modbus Plus.
MBPSTAT
Use the bridge’s MBPSTAT diagnostic to check Modbus Plus communication.
MBPSTAT will show a list of active Modbus Plus nodes that are recognized by the
bridge. It will also monitor network activity and record a node’s error statistics.
MBPSTAT is detailed in Sections 6.6 through 6.17.
BDRESET
You can also initialize the bridge’s Modbus Plus card without having to cycle
power, by using the BDRESET program.. It is detailed in Section 6.4.
