什么是DCS的开放性？
DCS的开放性是指DCS能通过不同的接口方便地与第三方系统或设备连接，并获取其信息的性能。这种连接主要是通过网络实现的，采用通用的、开放的网络协议和标准的软件接口是DCS开放性的保障。我公司目前采用的DCS系统有很好的开放性。
19、什么是系统冗余？
在一些对系统可靠性要求很高的应用中，DCS的设计需要考虑热备份也就是系统冗余，这是指系统中一些关键模块或网络在设计上有一个或多个备份，当现在工作的部分出现问题时，系统可以通过特殊的软件或硬件自动切换到备份上，从而保证了系统不间断工作。通常设计的冗余方式包括：CPU冗余、网络冗余、电源冗余。在极端情况下，一些系统会考虑全系统冗余，即还包括I/O冗余。
