o Actual module identification (such as, electronic keying) is done when
connection establishment requests are received from the controller or
controllers.
 A module removed under power does not disrupt operation of the other I/O
modules.
o When you remove a module, the adapter determines what changed.
o Whenever you remove a module with an active connection from the
POINT I/O system, the adapter indicates this by flashing the POINTBus
Status LED red and reports a minor recoverable fault.
 If more than one contiguous module is removed under power, connections to
all modules in the contiguous missing module set are disallowed until all
modules are replaced. Because the adapter cannot detect an empty base, it
does not know the physical positioning of the modules until all the missing
modules are replaced.
 If a module separating two sets of contiguous missing modules is removed,
the two sets merge into a single set. All the modules must be replaced before
connections are permitted to any module in the set.
 If modules of different types are removed and returned to the wrong
locations, attempts to connect to these modules will fail during verification of
the electronic ID (providing that keying has not been disabled).
 If modules of the same type are removed and returned to the wrong
locations, they accept connections from the controller or controllers and
reconfigure with the correct data once they pass their electronic keying
check.
 These removal and return situations exist whether the system is under power
or not. If the system is under power, the situation arises immediately. If the
system is not under power, the situation arises in the next power cycle.
