Board Mounted in the I/O Expansion Unit cannot
be Accessed
No Input or Output can be Performed on I/O Ports
(1) Is the board mounted correctly in the I/O expansion unit?
(2) Are the I/O port addresses set for the board you mounted in the I/O
expansion unit correct?
(3) Is any I/O port address of the board you mounted in the I/O
expansion unit unique?
(4) Is the board you mounted in the I/O expansion unit subject to any
of the restrictions that apply to this product?
If multiple boards are mounted in the I/O expansion unit, verify
operations with only one board mounted.
Verify simple input and output operations using a sample program, for
example.
If more than one board of the same type exists, replace them with one
another to verify operations.
