DCS系统得到上位机的数据采集要求后，便把上位机所要求的过程数据进行数据打包处理并发给上位机。为了提高通信效率，上位机一次要求的数据不止一个，DCS系统回应的数据包中包含这些数据，这样便要求有一个解开数据包的子模块。本系统的数据采集解数据包子模块利用数据过滤的算法得到单个过程数据，之后把此过程数据放入一个过程数据集合中，于是便得到各个过程数据。

四、多串口数据采集软件的易用性和健壮性 
4-1 多串口数据采集软件的易用性：即程序界面、人机接口的友好性
在生产调度监测系统中，只有系统维护人员可以看到数据采集软件的界面。由于数据采集软件需要同时采集多个DCS系统的数据，因此给数据采集软件的编写、调试以及维护带来相当大的困难，数据采集软件利用VB的多页面控件实现了本系统的多串口通信数据显示功能，这种界面给系统开发维护人员提供极大方便。 
在一个窗口上可以同时看到多个串口数据，只需鼠标在所需要的串口上567等）一点，此串口的接收和发送的数据即显示出来。

4-2 多串口数据采集软件的健壮性：通信自动恢复功能和事件日志功能
在通信过程中，可能有意外的事件发生，例如停电造成Modem不能通信等等情况，这些情况会造成通信出错而导致系统失败。数据采集软件对各种意外事件均做了相当充分的考虑，如Modem停电或断线等，在恢复供电后或Modem断线重新挂接后，数据采集软件可以判断并进行自动恢复工作。
当有通信意外事件发生时，数据采集软件自动地把出现的意外事件记录到数据库中，便于维护人员分析。在生产调度系统运行一年多以来，没有出现因为数据通信有误而导致系统失败的情况发生，其中数据采集软件的通信自动恢复和事件日志功能起了关键性的作用。MKS Instruments Model: 919
