National Instruments Corporation C-9 FieldPoint FP-3000 User Manual
FF_VAL
The feed-forward value.
FIELD_VAL
The value from the input channel, in percent of scale.
FP_AUTOCONFIGURE
This parameter, present in the resource block, causes the FP-3000 to
automatically configure itself. The FP-3000 detects all the I/O modules
present and instantiates the appropriate I/O function blocks. It creates a
function block for each I/O channel. It tags the function blocks and sets the
contained parameters to appropriate defaults. The resource block must be
set to OOS mode before you set the Autoconfigure option. If Autoconfigure
is set on an existing configuration, the FP-3000 deletes all the existing
blocks and linkages before creating new blocks.
FP_MOD_LIST
This parameter, present in the resource block, lists all the I/O module types
that are currently plugged in.
FREE_SPACE
The percentage of free memory available on the device. This can be used
when instantiating blocks to determine the remaining capacity of the
FP-3000.
FREE_TIME
Unused in FieldPoint.
GAIN
The gain constant used by the PID in calculating the proportional
component of the output.
GRANT_DENY
Allows MMI applications to determine access privileges for block
parameters.
Note The device does not use this parameter to restrict parameter access itself. It is only
for the benefit of host applications.
