ALK,
There is no inherent feature of the Compact FieldPoint unit
to be able to have this type of redundant dual controller. But at an
application level you could probably create this behavior.
Depending on what kind of “failure” you trying to protect
against there could be several different approaches. Either way you would have
to have your two controllers managing two separate but nearly identical banks.
Then have the backup bank monitor the first bank and if/when your first bank
fails, the second one kicks in and runs the same code.
If, for instance, you are worried about network failure, you
can use the network watchdog and if the network fails then have a something
like a digital line go high that the second bank is monitoring to know when to
take over.
For other types of failure, you will want to look at similar
types of schemes, but as I mentioned there will be no inherent way to do this
with FieldPoint. I hope this has helped, if you have any more questions about
this feel free to post back.
