05704-A-0121向高性能小型化方向发展。PLC的功能正越来越丰富，而体积则越来越小。比如三菱的FX-1S系列PLC，最小的机种，体积仅为60×90×75mm，相当于一个继电器，但却具有高速计数、斜坡、交替输出及16位四则运算等能力，还具有可调电位器时间设定功能。PLC已不再是早期那种只能进行开关量逻辑运算的产品了，而是具有越来越强的模拟量处理能力，以及其他过去只有在计算机上才能具有的高级处理能力，如浮点数运算、PID调节、温度控制、精确定位、步进驱动、报表统计等。从这种意义上说，PLC系统与DCS（集散控制系统）的差别已经越来越小了，用PLC同样可以构成一个过程控制系统。 

05704-a-0121 operation is developing in the direction of simplification. At present, one of the difficulties of PLC promotion is that complex programming makes users prohibitive, and the programming languages used by PLCs from different manufacturers are also different. Users often need to master a variety of programming languages, which is more difficult. The programming and application of PID control, network communication, high-speed counter, b control, data recording, bula and text display are also the difficulties in 05704-a-0121 programming. When programming them with ordinary bs, you need to be familiar with the significance of relevant special memories, assign values to them during programming, and realize the corresponding functions by accessing them during operation. These programs are often related to interruption. The programming process is cumbersome and error prone, which hinders the further popularization and application of 05704-a-0121. The development of 05704-a-0121 is bound to move towards the direction of simplified operation. For example, Siemens is the pioneer in using programming wizard to simplify the programming of complex tasks. Siemens S7-200 programming software has designed a large number of programming wizards. Only by bting some beters in the dialog box, it can automatically generate user programs including interrupt programs, which greatly facilitates the use of users.
