SnapShot Feature
Many applications require that, on startup, the system’s I/O modules power
up with user-specified configuration and output levels rather than factory
default settings. The SnapShot feature provides you with a single-step
method to store the current state of your FieldPoint bank for use as the
power-up state of the bank.
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 SnapShot.
Before you store the SnapShot, bring all the channels to the desired
power-up settings. You can use the FieldPoint Explorer software to change
the configuration of the FieldPoint bank, and then store the SnapShot. The
SnapShot stores all the following information in a single step:
•
Attribute and range settings of each channel.
•
Output values of each channel.
•
Watchdog data values 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 enabled (or disabled) status of each module. See the
section in this chapter for more information.
After you store the SnapShot information, you can still choose whether the
FP-1600 uses that stored information during future power-ups. Enable the
SnapShot feature if you want the FieldPoint bank to power up with the
stored SnapShot information.
If you have enabled the SnapShot feature, the FP-1600 restores the stored
settings to all I/O modules and channels in the bank every time you power
up until you disable the SnapShot feature. If the 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, use the
features described in the next section,
Note
The current watchdog timeout value for the FieldPoint bank is not saved when you
store the SnapShot.
