4.3.1 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 block sequence (page
114).
 The next controller tags are used to request and receive Client status data via
the Client Status block functionality (page 122).
 The next controller tags are the Event Sequence tags (blocks 4000 4100, and
4200), described on pages Error! Bookmark not defined. through Error!
Bookmark not defined..
 The remaining controller tags are used to request and receive server status
data via the Server Status block functionality (page 123).
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 use the server capabilities, your MVI56E-MNETC module needs to have firmware version
3.01 or higher, and your MVI56E-MNETC Add-On Instruction needs to be version 1.8 or higher.
Earlier versions do not support server capabilities.
