(b) Instructions available from function version B
*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.
*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.
