This chapter describes the feature set for the FP-20xx network module.
The network watchdog feature of the FP-20xx enables you to guard your
system against failures in the network connection, cables, or host computer.
If the network watchdog is enabled and the FP-20xx loses communication
with all hosts or clients over the network, the FP-20xx sets its output
channels to predefined values (the watchdog state).
Network watchdog output values can be different than power-up output
values. For example, you may want to turn on an output value when you
power up, but turn it off if network communication is lost.
The network watchdog for the bank is disabled by default. Follow these
steps to enable it:
1. In FieldPoint Explorer, right-click an output module and select
Edit this device.
2. Select Enable or Enable on Use for the current watchdog
configuration.
3. Click Channel Configuration, then configure these settings:
• Enable/disable the watchdog for each channel.
• Enter a watchdog data value for each channel.
4. Click OK.
