High-speed input/output designation method
High-speed input/output is designated by setting the corresponding bit of the bit selection parameter as shown below.

If there are multiple remote I/O connection channels, designate RIO2 with the same configuration as RIO1 above.
RIO2: Designate X100 to X1FF with bit selection parameters #6459 and #6460
RIO3: Designate X200 to X2FF with bit selection parameters #6465 and #6466

If there are multiple remote I/O connection channels, designate RIO2 with the same configuration as RIO1 above.
RIO2: Designate Y100 to Y1FF with bit selection parameters #6463 and #6464
RIO3: Designate Y200 to Y2FF with bit selection parameters #6473 and #6474
 As listed above, one bit corresponds to two bytes (16 points).
 Input or output in which 1 is set in the table is not performed at the main processing program level.
 Although the number of bits set to 1 is not limited, set only necessary ones from viewpoint of overhead.
 High-speed input/output designation corresponds to the bit selection parameter and can be set in the parameter. However,
it is recommended to set in a sequence program to prevent a parameter setting error, etc.
