1、人机对话操作台。这是监控系统的早期产品类型，是生产厂家专为自己的PLC产品设计的，适合于点对点控制。结构简单，功能少，面板控制，操作较易，现仍然广泛地应用于现场控制系统中。其优点是在远端控制失效的时候，仍能很好地控制现场。
2、随着计算机的不断发展，依靠PC（包括工控机）的监控系统越来越多地应用在自控系统中，这种监控系统一种是PLC开发商专为自己的（或特定的）产品量身定做的；另一种是软件开发公司开发的适合大多数PLC产品的监控系统。前一种与PLC产品的相容性强，能够根据PLC产品的特点制定相应的控制方案，应该说仍以PLC为中心；后一种则抛开了PLC产品，注重计算机在图像、动画、声音、网络、数据等方面的优势，给二次开发人员提供了较宽松的开发条件，往往可以制作出的监控系统，只要有相应的通信协议（目前已拥有了绝大多数生产厂家的通信协议），就可以与各种类型PLC相连，是当今自控系统。所以，在这方面应考虑所选的PLC与监控系统的通信方式是否可行。
六、可延性
这里包括三个方面含义：
1、产品寿命。大致可以保证所选择的PLC的使用年限，尽量购买生产日期较近的产品；
2、产品连续性。生产厂家对PLC产品的不断开发升级是否向下兼容，这决定是否有利于现系统对将来新增加功能的应用。
3、产品的更新周期。当某一种型号PLC（或PLC模块）被淘汰后，生产厂家是否能够保证有足够的备品（或备件）。这时应考虑选择当时比较新型的PLC。
七、售后服务与技术支持
1、选择好的公司产品；
2、选择信誉好的代理商；
