Note: Each bank has only one watchdog timeout value that is common for all the
modules in that bank. In addition, the current watchdog timeout value is
not stored when you store the SnapShot.
SnapShot Feature
Many applications require that, upon 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.
Prior to storing the SnapShot, you should bring all the channels to the
desired power-up settings. You can use either the FieldPoint Server
software or the FieldPoint command set 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
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-1000/1001 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-1000/1001 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
