Discrete manufacturing typically involves a series of steps on a single piece of equipment to create the final product.Electronic and mechanical parts assembly and part machining are typical examples of such industries.Both process-based and discrete industries use the same types of control systems,sensors and networks.Some facilities are a mix of discrete and process-based manufacturing.Although the control systems used in distribution and manufacturing are very similar in operation,they are different in some ways.The main difference is that DCS or PLC-controlled subsystems are usually located in narrower factory or plant-centric areas,compared to geographically dispersed SCADA sites.DCS and PLC communications typically use local area network(LAN)technology which is typically more reliable and high-speed long-distance communications systems used by SCADA systems

离散制造业通常在单个设备上进行一系列步骤创造最终产品。电子和机械零件组装和零件加工是典型的这种行业的例子。基于过程和离散的行业都使用相同类型的控制系统，传感器和网络。一些设施是离散和基于过程的制造业的混合体。虽然在分销和制造业中使用的控制系统在运行中非常相似，他们在某些方面是不同的。主要区别在于DCS或PLC控制的子系统通常位于较为狭窄的工厂或植物为中心的地区，与之相比地域分散的SCADA现场。DCS和PLC通信通常使用局域网（LAN）技术通常比较可靠和高速度SCADA系统使用的长途通信系统
