*1 If the processing overlaps those of the other CPUs in a multiple CPU system, the processing time increases by a maximum of the
following time.
• For a system having only the main base unit
(Instruction processing time increase) = 4  0.54  (number of points processed)  (number of other CPUs) (s)
• For a system including extension base units
(Instruction processing time increase) = 4  1.30  (number of points processed)  (number of other CPUs) (s)
