这种开发方式的优点是显而易见的，厂商的开发成本低，灵活度高，但是需要数控厂商提供相当多的技术支持，如果客户数量多则厂家很难有足够的支持能力，所以这类厂商大多都希望能开发方案二的数控平台。
楼宇控制可以说是一个很好玩的行业，价格奇高，但功能却不并复杂，所以现在有很多工程商在使用小点数的PLC组网代替DDC，但在易开发方面相对要差一些（主要是监控软件），主要是楼宇本身是高利润行业，大家对一个点近千元的价格并不感到无法承受，只有当楼市价格下降竞争大了才会有可能重视成本方面。
个人认为未来楼控很难作为一个单独的控制器种类存在，而会被其它产品给吞并，例于PLC。
数采行业因为受到了GPRS、GSM等业务的影响，正出现一次比较大的变革，特别是在远距离方面，传统的MODEM、RTU方式正受到很大的冲击，在我们经手的很多环境监控、管道监控、路灯节能、水文监控方面很少有客户能经受GPRS DTU的诱惑。DTU的基于网络和透明通信方式深受大家的喜爱，只是目前DTU的价格相对而言还是比较高，如果能掉到GSM MODEM的价格就比较合适了。除此之外移动对于数据业务的支持还是不够，早期还可以用神州行卡，现在已全部关闭了，只能用全球通，而全球通每月50元的月租实在让人很恼火，一个城市的路灯节能控制器如果全部上GPRS，假设有1000个点，那么每个月就需要5万元的开支，还不包括流量的收费，对于公共事业这还算好，对于工厂或者电梯的监控就很难受了。
