4.3.1 Status Data Definition

This section contains a description of the controller tags in the SIE.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

138).

 The remaining controller tags are used to request and receive Client status

data via the Client Status block functionality (page 143).

Note: In order to access up-to-date status data from these remaining controller

tags, a Client Status block must be recently received from the module. Client

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 from the

processor.
