(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.
