DS200ACNAG1ACC

PLC硬件和软件的进展
PLC硬件和软件的进展,从系统上讲是实现小型化、高速化,以及将信息技术渗入PLC;从硬件上讲是,采用32位RISC的MPU、专用的LSI和多CPU;从软件上讲则是,采用与国际标准IEC 61131-3相对应的日本工业标准JIS B 3503。
小型化 由于日本电子工业尤以器件、电路板等硬件见长,所以在PLC系统上实现小型化,可以说最早就是起源于日本,又由他们来推动,并一直乐此不疲、贯彻至今的。小型化的好处是:节省空间、安装灵活、降低成本。
现今日本主要PLC厂商生产的模块式中、大型PLC,其典型的外形尺寸要比他们在前一代的同类产品的安装空间要小50-60%。例如三菱电机的小Q系列就比AnS系列的安装空间减少60%。要做到这一点,首先需要开发大规模的专用集成电路芯片(ASIC)来减少芯片的个数,并采用球栅阵列(BGA)以保证在同样封装尺寸下能提供足够多的针脚数。例如,某CPU模块原来用了约700个元器件,通过开发了12种大规模的ASIC(采用BG352的针脚封装)和调整功能,减少了显示用的LED和开关等措施,使元器件减少了一半左右。其次,为减少接插件在印刷电路板上所占的空间,要求接插件的针脚间隔足够小。再次,随着微细加工技术的发展,印刷电路板上的接线布局可实现高密度化、多层化和薄型化,大大提高了元器件的安装率。例如某CPU模块采用了1毫米厚的基板制成8层电路板。由于采取了以上这些措施,使CPU模块由3块印刷电路板变为2块,体积减少了70%,小型化得以较完美地实现。随着小型化又产生了如何解决小空间的散热设计问题:一是要根据热分析仿真来确定元器件的布置安排;二是主要元器件的电源电压采用3.3V,达到低功耗的目的;三是考虑了通过安装模块的基板,使模块所产生的热量能得到良好散热的机械结构。
高速化 所谓高速化应该包括:运算速度的高速化;与外部设备的数据交换速度高速化,如I/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。

先介绍几点经验。
1、先通读一遍“系统手册”(不管能不能看懂,先了解个大概,以便学习编程时查找);
2、由位控逻辑入手,逐渐增加定时、计数等条件,把或、与、非关系理顺;
3、进而练习整数运算、实数运算、类型转换;
4、量程转换、PID调节回路的建立及P、I、D参数的理解(最好是有个物理回路验证,比如变频器+电机+测速传感器);
5、循环、顺序、跳转等程序控制(尽量避免跳转,非跳不可时也是跳的越近越好);
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列,GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌,由于PLC的基本框架大同小异,学会一种至于其它的学习起来也就简单了。
