*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 system having only the main base unit
(Instruction processing time increase) = 0.54
processed)
For system including extension base units
(Instruction processing time increase) = 1.30
processed)
*2 : In a multiple CPU system, the instruction processing time for the intelligent function module under control
of the host CPU is equal to that for the intelligent function module under control of another CPU.
*3 : Products with the first 5 digits of the serial No. "07032" or higher are applicable.
