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.
Table 5: Structure for I/O Module Status Data
Identifier Type Description Remarks
<tagname>.EXPC INT Modules expected Reports the number of modules that are
defined in the configuration for the group (1, 2
or 3)
<tagname>.ACT INT Modules on-line Reports the number of modules in a group
that are installed, powered, locked and
communicating over the I/O bus (1, 2 or 3)
<tagname>.LOC INT Slot location Reports the slot number of the left-most
module position for a group, irrespective of
whether a module is physically located in a slot
(1 to 24) (†)
<tagname>.GH BOOL Group health Reports the general health status of all
modules in a group
TRUE: all modules are healthy
FALSE: one or more modules in the group is
on-line and reporting a fault
<tagname>.XONL BOOL On-line status Reports the on-line status of module X
TRUE: the module is installed, powered,
locked and is communicating over the I/O bus,
otherwise FALSE
<tagname>.XHLY BOOL Health status Reports the general health of module X
TRUE: the module is on-line and has no faults,
otherwise FALSE
<tagname>.XRDY BOOL Ready status Reports the ready status of module X
TRUE: the module is on-line and ready to
report channel values, otherwise FALSE
