Possible causes for an I/O module fault are:
transmission errors on the FLEX I/O backplane
a failed module
a module removed from its terminal base
an incorrect module inserted in a slot position
an empty slot
The node address changed bit is set when the node address switch setting has
been changed since power up. The new node address does not take effect until
the adapter has been powered down and then powered back up. Until this power
cycling occurs, the node address switches will not match the actual node address.
