DOP Instances 3 and 4 Special Behavior

There are many sources that can affect an output point’s value: an I/O
message, and explicit message, local logic, network fault and idle
conditions, and protection fault conditions. An output point must
know how to select which source of data to use to drive its value
attribute.

An output that is not bound behaves much the same as in the
DeviceNet Specification. One notable addition to DOP behavior for
the ArmorStart implementation is the Protection Fault Action and
Protection Fault Value attributes determine the behavior of the DOP
when the ArmorStart faults on a protection fault.
