Appendix B Fieldbus Parameters
FieldPoint FP-3000 User Manual B-8 www.ni.com
FF_GAIN (Scaling, Tuning)
The gain by which the feed-forward input is multiplied before it is added to
the output value of the control block.
FF_SCALE (Scaling)
The scaling parameter used by the feed-forward value of the block.
FF_VAL (Process, Scaling, Tuning)
The feed-forward value.
FIELD_VAL (Process, Scaling, Tuning)
The value from the input channel, in percent of scale.
Table B-3. Feature Parameter Options
Option Description
Unicode
The device supports strings in
Unicode
format. The FP-3000 does not
support this feature.
Reports
The device supports event report messages for alarming. If this feature
is not selected in the
FEATURE_SEL
parameter, the FP-3000 continues
to detect alarms and events, but does not report them over the bus.
In this case, the host must poll the alarm parameters to detect alarm
conditions as they change.
Faultstate
The device supports
Faultstate
behavior for output blocks.
Soft Write Lock
The device supports locking of configuration of parameters with the
WRITE_LOCK
parameter in the resource block. With this feature
selected and the
WRITE_LOCK
parameter written to
Set
, writes to all
static configuration parameters are disallowed.
Hard Write Lock
The device supports locking of configuration parameters. For the
FP-3000, a switch on the back of the device must also be set. If
Hard
Write Lock
is enabled, the switch disallows writes to all
configuration parameters in the device, including
FEATURE_SEL
.
Out Readback
The device provides a way for the action of output transducers to be
verified through a readback. The FP-3000 does not support this
feature.
Direct Write
The device provides a manufacturer-specific way to directly write to
I/O channels. The FP-3000 does not support this feature.
