For more information about status data in MNETC.STATUS, see the Status Data
Definition (page 93).
In ProSoft Configuration Builder's Diagnostics screens.
For more information, see the section on The Diagnostics Menu (page 88).
In database locations specified by Error/Status Pointers (optional).
If optional Error/Status Pointers are enabled, status data can also be found in the
Read Data area of the module's database at the locations specified by the
pointer configuration parameters. For more information, see Backplane
Error/Status Pointer (page 36), Client Error/Status Pointer (page 42) and
Command Error Pointer (page 42).

4.5.1 Status Data Definition

This section contains a description of the controller tags in the MNETC.STATUS
controller tag structure, which contains module and Client status data.

The first ten controller tags contain status data routinely transferred from the
module to the processor in the Normal Data Transfer Blocks (page 106).

The next controller tags are used to request and receive Client status data via
the Client Status Blocks (3000 to 3029) (page 114).

The next controller tags are the Event Command Blocks with Sequence
Number (4000 to 4029, 4100 to 4129, 4200) (page 116).

The remaining controller tags are used to request and receive server status
data via the Server Client Status Blocks (3000 to 3029) (page 114).
Note: In order to access up-to-date status data from these remaining controller
tags, you must ensure that a Client Status block or Server Status block was
recently received from the module. Client Status blocks and Server Status blocks
are not routinely sent from the module; they are returned on a once-per-request
basis as a response to a Client Status block request or Server Status block
request from the processor.
Note: To take advantage of the new features described above, your MVI56E-
MNETC/MNETCXT module needs to have firmware version 3.01 or higher, and
your MVI56E-MNETC/MNETCXT Add-On Instruction needs to be version 1.8 or
higher. Earlier versions have no server capabilities and support only up to 5000
user database registers.
