让以Windows操作系统的PC机嵌入PLC系统[见上述*（1）节]。
2）创建开放的网络环境。如推出能挂100M的高速以太网的Web服务器模块（三菱电机小Q系列的QJ71WS96，横河电机FA-M3系列的F3WBM1-0T-S01），模块内的软件捆绑了目前常用的TCP/IP、UDP/IP等传输层和网络层的规约，以及HTTP、FTP、SMTP、POP3等应用层的规约，使PLC可直接进入因特网，成为不折不扣的基于Web的PLC；也可使产的PLC挂上以德国Siemens公司为主导的工业以太网ProfiNet。在这次系统控制展览会上，我们就见到Profibus组织（JPO）的展台上展出的通过多种方式挂ProfiNet的PLC，富士电机的MICREX-SX系列PLC、横河电机的FA-M3系列PLC都是直接经由其以太网模块挂ProfiNet的，三菱电机的小Q系列PLC则是通过其RS 232C的模块和外挂的RS 232C/以太网协议转换器（JNVE1型）挂ProfiNet的。
