摘要
随着许多厂商已生产出能结合PC功能和PLC可靠性的可编程自动化控制器（PAC），目前PAC已愈来愈多地应用到控制系统中。本文探讨了PAC的起源以及它与PLC和PC的区别，并指出了应用PAC的工业控制的未来发展方向。
With a number of vendors producing Programmable Automation Controllers that combine the functionality of a PC and reliability of a PLC, PACs today are increasingly being incorporated into control systems. This paper explores the origins of the PAC, how PACs differ from PLCs and PCs, and the future direction of industrial control with PACs.
