High-speed operation is also an important goal of Japanese PLC system. Because the CPU modules of PLC are competing to use 32-bit RISC chips, the computing speed is greatly improved. Generally, the execution speed of basic commands reaches tens of nanoseconds (ns). For example, the execution time of input commands of Mitsubishi Electric’s Q02HCPU is 34ns, the execution time of Fuji Electric’s MICREX-SX series SPH300 is 20ns, and the execution time of input commands of Yokogawa Electric’s FA-M3 series F3SP59-7S is 17.5ns. Just looking at the execution time of an instruction does not completely explain the problem. JEMA, the Japan Electric Machinery Industry Association (JEMA), has always advocated the use of PCmix value (i.e., the processing time performance of PLC as an indicator, expressed by the average number of basic instructions and data processing instructions executed in 1 microsecond) to measure the operation speed of PLC. The average number of basic instructions and data processing instructions executed in 1 microsecond is calculated according to the statistical average of the frequency of the instructions used by the PLC application program. Generally, basic instructions account for 54% (including 17% of input instructions, 13% of output instructions, 21% of logic operation instructions, and 3% of timer output), data processing instructions account for 39% (including 25% of transfer instructions, 6% of four function operation instructions, and comparison instructions), and other instructions account for 7%. Taking the small Q series of Mitsubishi Electric as an example, the PCmix value of Q25HCPU is 10.3, 5 times faster than A2UHCPU-S1 (2.0), and more than 20 times faster than A2SHCPU (PCmix value is 0.5). With the expansion of PLC functions, more and more operation instructions, word processing instructions and communication instructions are used. The frequency of various instructions will also change, and the calculation of PCmix value will also change. By the way, the reason why Mitsubishi Electric is cited for many times is that its PLC market share accounts for more than 50% in Japan, and it is the largest PLC supplier in Japan, so it is quite typical. At the same time, the level of PLC special operating system is improved through software technology, and the high-speed response (200 microseconds) function of event interruption, high-speed counting function, constant scanning time function of 0.5 ms (Mitsubishi Electric’s small Q series PLC), and even 0.2 ms (Yokogawa Electric’s FA-M3 series PLC) are realized
