主机还可向PLC写数据，进行单点的强近置位和复位。
对于运行在控制和实验室环境飞速下本方案运行可靠、性价比高、体积小、但是对于通信距离长，环境恶劣的发问，需加光电隔离等措施。
用户希望能通过PLC在软技术上协助改善被控过程的生产性能；需要PLC能与PC机更好地融合，以便于在PLC这一级就可加强信息处理能力。为顺应这些要求，CONTEC与三菱电机合作，推出专门装插在小Q系列PLC的机架上的PC机模块。该模块占2个插槽，实际上就是一台可在工厂现场环境正常运行、而且可通过PLC的内部总线与PLC的模块交换数据的PC机。其处理机芯片采用Intel的Celeron 400MHz主频，系统内存128MB，Cache 128K。支持外挂显示器（大分辨率1024x768，65,536色，显存2MB）。接口有：USB 1个，可扩至2个；以太网插口RJ45（10BASE-T/100BASE-TX0；串口RS 232C 1个，可扩至2个；并口可扩1个；鼠标、键盘口PS/2；外挂软盘驱动器口；外挂硬盘驱动器口；以及2个PC卡件（PCMCIA总线）。硬盘模块或固态盘可插装在PLC机架上。该模块可预装Windows NT 4.0或Windows 2000。支持的软件有：三菱综合FA软件MELSOFT（包括PLC编程软件：GX；FA数据处理、日常业务处理加速中间件：MX；人机界面画面设计编程软件：GT；运动控制设计编程维护软件：MT；以及过程控制设计编程维护软件：PX）。另外，还支持三菱FA用的通信中间件EZSocket。
