I/O refresh processing time
The I/O refresh processing time for module mounted on main base unit and extension base unit can be calculated by the
following formula.
I/O refresh processing time [s] = ((Number of input refresh points
*3
 KM2) + KM3
) + ((Number of output refresh points
*3
KM6 )
*1 The value indicates the numeric value that is obtained through dividing the number of input points by 16.
*2 The value indicates the numeric value that is obtained through dividing the number of output points by 16.
*3 When the number of I/O points is 0, this value is handled as 0.
