FieldPoint FP-1000/1001 User Manual
SnapShot feature is disabled, the FieldPoint bank powers up with
factory-default settings.
At some time you might want to change the stored SnapShot
information. To make incremental changes in the stored SnapShot
information, you can use the features described in the next section,
Programmable Power-Up State.
Note:
The current watchdog timeout value for the FieldPoint bank is not saved
when you store the SnapShot.
Note:
The SnapShot feature inherently requires that the entire FieldPoint bank
be at your desired power-up state, since when you store the SnapShot
information, the current settings of the entire bank are stored for use at
future power-ups.
Programmable Power-Up State
The SnapShot feature described in the SnapShot section provides you
with a single-step method to store the current state of the FieldPoint
bank for use as the power-up state. The FP-1000/1001 provides an
alternative method to define power-up states that allows you to store the
SnapShot information with more flexibility, as described in this section.
The Programmable Power-Up State feature enables you to define the
power-up configuration on a module-by-module basis. In addition, you
do not need to actually set any of the channels to the desired power-up
state. You can therefore define the power-up states regardless of the
current settings of any channel of a module.
Optionally, you can utilize the Programmable Power-Up State feature
to incrementally modify previously stored SnapShot information.
If you subsequently enable the SnapShot feature, you can ensure that
your system powers up with the configuration and output levels that you
specified when storing the Programmable Power-Up States.
