3.3 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.
(1) High-speed input designation
(2) High-speed output designation
· 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.
Example: —[MOV H3 R2928]— ..... To designate X00~X0F, X10~X1F (bit 0 and 1 for H3)
