SCXI_Get_Chassis_Info
Returns chassis configuration
information.
SCXI_Get_Module_Info
Returns configuration information for
the assigned SCXI chassis slot number.
SCXI_Get_State
Gets the state of a single channel or an
entire port on any digital or relay
module.
SCXI_Get_Status
Reads the data in the status register
on the specified module. You can use
this function with the SCXI-1160 or
SCXI-1122 to determine if the relays
have finished switching, with the
SCXI-1124 to determine if the DACs
have settled, with the SCXI-1126 to
determine if the module has settled
after changing any of its programmable
functions (ranges, filter settings,
threshold, or hysteresis), or with the
SCXI-1102/B/C to determine if the
module has settled after changing
gains.
SCXI_Load_Config
Loads the SCXI chassis configuration
information that you established in the
Measurement & Automation Explorer.
Sets the software states of the chassis
and modules present to their default
states. No changes are made to the
hardware states of the SCXI chassis
or modules.
SCXI_ModuleID_Read
Reads the Module ID register of
the SCXI module in a given slot.
The principal difference
between this function and
SCXI_Get_Module_Info
is
that
SCXI_ModuleID_Read
does
a hardware read of the module. You
can use this function to verify that
your SCXI system is configured
and communicating properly.
