6.3 Network Diagnostics
6.3.1 MBTCP PCB Diagnostics
The best way to troubleshoot the MBTCP driver is to use ProSoft Configuration
Builder to access the diagnostic capabilities of the gateway through the Ethernet
debug port. For instructions on how to access the diagnostics, see Diagnostics
and Troubleshooting (page 31).
The following table summarizes the status information available in PCB for the
MBTCP driver:

6.3.2 MBTCP Status Data in Upper Memory
The MBTCP driver has an associated status data area located in the PLX3x
gateway
’s upper memory. The Data Map functionality of the PLX3x gateway can
be used to map this data into the normal user data range of the PLX3x gateway
’s
database.
Note that all the status values are initialized to zero (0) at power-up, cold boot
and during warm boot.
