3.3.5 MNET Client Command List Error Data

Each command in the command list for the MNET Client has a reserved word

value for a status/error code. This error data list can be read using the

Debug/Config Port and can be placed in the gateway’s internal database.

The first word in the register location defined contains the status/error code for

the first command in the Client Command List. Each successive word in the

Command Error List is associated with the next command in the Client

Command List. Therefore, the number of valid error values is dependent upon

the number of commands defined. The structure of the data area is displayed

below:

Internal Database Address Description

6010 Command #0 Error Status

6011 Command #1 Error Status

6012 Command #2 Error Status

6013 Command #3 Error Status

6014 Command #4 Error Status

6107 Command #97 Error Status

6108 Command #98 Error Status

6109 Command #99 Error Status

Note that the values in the Command List Error Status tables are initialized to

zero (0) at power-up, cold boot and during warm boot. Refer to the next section

containing Error Codes to interpret the status/error codes present in the data

area.
