6.3 MBTCP Diagnostics
6.3.1 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 Diagnostics, see
Using
Diagnostics in ProSoft Configuration Builder (page 36).
6.3.2 MBTCP Status Data in Upper Memory
The MBTCP driver has an associated status data area located in the gateway’s
upper memory. The Data Map functionality of the gateway can be used to map
this data into the normal user data range of the gateway
’s database. See Using
the CommonNet Data Map (page 25).
Note that all the status values are initialized to zero (0) at power-up, cold boot
and during warm boot.
MBTCP Server Status Data
The following table lists the addresses in upper memory where status data for
MBTCP servers can be found.
Server Port Address Range
2000 6200 through 6209
502 6210 through 6219
2001 6220 through 6229
