• Watchdog enabled/disabled status for each I/O module.
• Watchdog timeout value for the bank.
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 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 will power 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 Network Watchdog
Timer section in this chapter for more information.
• Watchdog data enabled (or disabled) status for each channel. See
the Network Watchdog Timer section in this chapter for more
information.
• Watchdog enabled (or disabled) status of each module. See the
Network Watchdog Timer section in this chapter for more
information.
After you store the SnapShot information, you can still choose whether
the network module 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.
