(Note 1) Be sure to set the bits indicated - and blanks to 0.
(Note 2) Parameters #6481 to #6496 are reserved for debugging by Mitsubishi.
(Note 3) High-speed input specification is valid for only the devices allocated to remote I/O. As for
the devices allocated to the input signals from network such as HR863 Q-bus bridge or
H865 CC-Link, high-speed input specification is not applied to.
(Note 4) When using C64T system, these parameters are used as follows;
bit0 High-speed input specification from R54.
#6457
bit1 High-speed input specification from R55.
bit0 High-speed output specification to R56. #6458
bit1 High-speed output specification to R57.
