*2 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) = 0.54 (number of points processed) (number of other CPUs) (s)
• For a system including extension base units
(Instruction processing time increase) = 1.30 (number of points processed) (number of other CPUs) (s)
*3 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.
*4 Products with the first five digits of the serial No. "07032" or higher are applicable.
■Data link instruction
The processing time when the instruction is not executed is calculated as follows:
• Q02CPU: 0.079 (No. of steps for each instruction + 1) s
• Q02HCPU, Q06HCPU, Q12HCPU, Q25HCPU, Q02PHCPU, Q06PHCPU, Q12PHCPU, Q25PHCPU, Q12PRHCPU,
Q25PRHCPU: 0.034 (No. of steps for each instruction + 1) s
