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.
