154958 AB高速化所渭高速化应该包括:运算速度的高速化;与外部设备的数据交换速度高速化，如/O刷新和网络刷新等;编程设备服务处理的高速化;外部设备的高速响应。

A-B 154958运算速度高速化也是PLC系统追求的一个重要目标。由于目前PLC的模块竞相采用32位RISC芯片，运算速度大为提高。一般基本指令的执行速度均达到数十个纳秒(ns)，如三菱电机的Q2H其输入指令的执行时间为34ns，富士电机MICREX-SX系列SPH300达2Ons，横河电机的FAM3系列的F3SP59-78其输入指令的执行时间为17.5ns。仅看一种指令的执行时间并不能完整地说明问题。电机工业会(电机工业的协会)JEMA一直倡导用PCmix值(那PLC的处理时间能表示指标，用1做微秒执行的基本指令和数据处理指令的平均次数来表示)来衡量PLC的运算速度。所谓1微秒执行的基本指令和数据处理指令的平均次数，是按PLC应用程序所使用的指令的频繁程度的统计平均值计算的。一般是基本指令占54%(其中输入指令占17%，输出指令13%，逻缉运算指令21%，定时器输出3%)，数据处理指令占39%(其中传送指令占25%，四则函数运算指令，比较指令6%)，其它指令7%。仍以三菱电机的小Q系列为例，其中的Q25H的PCmix值是10.3，比A2UH-S1快5倍(为2.0)，比A2SH快20倍多(PCmix值为0.5)。A-B 154958随着PLC的功能扩展，运算指令、文字处理指令、通信指令等用的越来越多，各种指令的使用频率也会发生一定的变化，PCmix值的计算也会有所变化。这里顺便提一下，之所以要多次举三菱电机为例，是因为它的PLC的市场份额占的50%以上，为的大PLC供应厂商，因而具有相当的典型。同时，通过软件技术提升PLC专用操作系统的水平，实现了事件中断的高速响应(200微秒)》功能，高速计数功能，0.5毫秒(三菱电机的小Q系列PLC)、甚至0.2毫秒（横河电机的的FA-M3系列PLC)的恒定扫描时间功能.

154958 AB high-speed high-speed should include: high-speed computing speed; High speed of data exchange with external devices, such as /O refresh and network refresh; High speed of programming device service processing; High speed response of external devices.

A-B 154958 High computing speed is also an important goal of PLC system. As the current PLC modules compete to use 32-bit RISC chip, the computing speed is greatly improved. The execution speed of basic instructions in general reaches tens of nanoseconds (ns), such as Mitsubishi Motor's Q2H, its input instruction execution time is 34ns, Fuji Motor's MICREX-SX series SPH300 is 2Ons, Yokogawa Motor's FAM3 series F3SP59-78, its input instruction execution time is 17.5ns. Just looking at the execution time of an instruction does not tell the whole story. The Motor Industry Association (motor industry association)JEMA has been advocating the use of PCmix value (the PLC processing time can represent the indicator, expressed by the average number of basic instructions and data processing instructions executed in 1 microsecond) to measure the computing speed of PLC. The average number of basic instructions and data processing instructions executed in the so-called 1 microsecond is calculated according to the statistical average of the frequency of the instructions used in the PLC application. Generally, basic instructions account for 54%(input instructions account for 17%, output instructions 13%, logic operation instructions 21%, timer output 3%), data processing instructions account for 39%(transfer instructions account for 25%, four function operation instructions, comparison instructions 6%), and other instructions 7%. Taking Mitsubishi Electric's Small Q series as an example, the Q25H has a PCmix value of 10.3, which is 5 times faster than the A2UH-S1 (2.0) and more than 20 times faster than the A2SH (0.5 PCmix). A-B 154958 With the expansion of PLC functions, more and more operational instructions, word processing instructions, communication instructions, etc., the frequency of use of various instructions will also change, and the calculation of PCmix value will also change. By the way, the reason why we have to take Mitsubishi Electric as an example many times is that its PLC market share accounts for more than 50%, and it is a large PLC supplier, so it is quite typical. At the same time, through software technology to improve the level of the PLC dedicated operating system, the realization of the event interrupt high-speed response (200 microseconds) function, high-speed counting function, 0.5 milliseconds (Mitsubishi Electric's small Q series PLC), and even 0.2 milliseconds (Yokogawa Electric's FA-M3 series PLC) constant scan time function.
