Think&Do和Steeperchase的VLC都是1998、1999年进入中国市场的，特别是Think&Do花了很大的努力，至今仍不尽如人意。当然有一些成功应用，如邮件分拣系统。我感觉，这多少与它们不采用IEC 61131-3，而是倡导用流程图编程语言不无关系。
德国KW公司在1998年以后就在北京设立办事处，着力推广其符合IEC 61131-3的编程系统MULTIPROG和控制程序ProConOS。
Siemens从2001年开始在国内推介其软PLC系列产品WinAC，已经有了一些应用。他们是很有战略眼光的。德国Inforteam公司的openPCS在国内也开始了市场开拓活动，2002年6月曾在上海的自动化展览会上举办过技术交流。
我国自行开发的DCS系统，如上海自仪公司的SUPMAX-800，选用法国CJ International公司的符合IEC 61131-3的IsaGraf和美国的强实时操作系统Vxworks。北京的和理时已采用Inforteam的OpebPCS开发新的DCS。
分析全世界控制设备的发展情况
从全世界范围看，软PLC/PC控制作为新兴产业正在发展。面对这种挑战，PLC仍在发展。
