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。
据美国Venture Development Corp.报告，2000年全世界共销售DCS系统，PLC系统和PC控制系统达220亿美元。其中DCS 40.5%；PLC 46.3%；PC控制13.2%。这三种控制系统所用的分散型/远程I/O的市场销售额也为220亿美元。年增长率为6.6%。到2005年估计达300亿美元。从应用领域看，DCS仍然牢牢把握大规模连续流程工业（I/O达数千点）过程控制的应用。PLC已经拥入批量控制市场，在其传统的离散制造工业仍然占据主导地位。软PLC/PC控制采用工控PC机（或嵌入式PC机）和强实时OS，可实现PLC功能和运动控制。直至，PC控制在可靠性、安全性等方面还未取得广泛认可。
