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.
You can use the Programmable Power-Up State feature to individually store
the following information. You can use either the FieldPoint Explorer
software or the FieldPoint command set.
•
Attribute and range settings of each channel
•
Output values of each channel
•
Watchdog data value of each channel. See the
section in this chapter for more information.
•
Watchdog data enabled (or disabled) status for each channel. See the
section in this chapter for more information.
•
Watchdog timer enabled (or disabled) status of each module. See the
section in this chapter for more information.
•
Power-up watchdog timeout value for the FieldPoint bank
•
The turn-around delay for each module
•
The hot-swap reporting mode for the FieldPoint stack. See the next
section,
, for more information on the
hot-swap reporting mode.
