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。
