DCS中的操作站用以完成系统的开发、生成、测试和运行等任务，这就需要相应的系统软件支持，这些软件包括操作系统、编程语言及各种工具软件等。

一套完善的DCS，在操作站上运行的应用软件应能实现如下功能：实时数据库、网络管理、历史数据库管理、图形管理、历史数据趋势管理、数据库详细显示与修改、记录报表生成与打印、人机接口控制、控制回路调节、参数列表、串行通信和各种组态等。

当大量现场信息由智能仪表或通过现场总线直接进入计算机控制系统后，存在着计算机内部应用程序对现场信息的共享与交互问题。由于缺乏统一的连接标准，工控软件往往需要为硬件设备开发专用的驱动程序。这样一旦硬件设备升级换代，就需要对相应的驱动程序进行更改，增加了系统的维护成本。

DCS operation station is used to complete the development, generation, testing and operation of the system, which requires the corresponding system software support, including the operating system, programming language and various tool software.

A complete set of DCS, the application software running on the operation station should be able to achieve the following functions: real-time database, network management, historical database management, graphic management, historical data trend management, database detailed display and modification, record report generation and printing, man-machine interface control, control loop adjustment, parameter list, serial communication and various configurations.

When a large amount of field information enters the computer control system directly through the intelligent instrument or the field bus, there is a problem of sharing and interacting the field information with the application program inside the computer. Due to the lack of a unified connection standard, industrial control software often needs to develop special drivers for hardware devices. In this way, once the hardware equipment is upgraded, the corresponding driver needs to be changed, increasing the maintenance cost of the system.
