PLC在硬件上也有长足进步。微电子技术的进展全都运用到PLC中，元器件的集成度越来越高，促使PLC成本下降和可靠性提高。专为PLC的设计的PLC-on-a-chip芯片业已问世多年。PLC的产品在体系结构和操作系统上都有了质的变化,性能大幅提高。一个机架上可装多个模块。也出现了以Web为基础的PLC系列产品。
PLC、软PLC、IEC 61131在中国的未来
传统的PLC制造业不会在可预见的未来在国内建立和发展。但不排除软PLC在近期和可预见的未来，完全有可能在国内形成一定的气候。软PLC的I/O完全可以利用主流及一些有生命力的现场总线的系列产品。强实时操作系统可采用Windows CE，NTE，VenturCom的RTX以及其它；只要它们能实现控制的时间确定性，即保证能以时间高度一致的方式执行控制指令序列，并具有可预测的结果或行为。加入WTO以后，中国成为"世界制造工厂"的进程正在加速。我们有足够的理由相信，PLC、软PLC在中国的销售的年增长率会显著**世界的平均年增长率。因此，对PLC、软PLC以及IEC 61131的推广应用，特别是高水平的技术支持变得十分重要。
