T9K_TA_GROUP_STATUS (I/O Module Status Information)
The data structure for module status information (T9K_TA_GROUP_STATUS)
provides the elements detailed in the table.
Note: The controller interrogates an I/O module (designated 'X' in the table)
according to the physical arrangement of the module and its position in a group. A
simplex module is designated as module A; a duplex module as A or B and a triplicated
module as A, B or C.
