FCS的关键要点有三点
(1)FCS系统的核心是总线协议,即总线标准
前面的章节已经叙述,一种类型的总线,只要其总线协议一经确定,相关的关键技术与有关
的设备也就被确定。就其总线协议的基本原理而言,各类总线都是一样的,都以解决双向串行数字化
通讯传输为基本依据。但由于各种原因,各类总线的总线协议存在很大的差异。
为了使现场总线满足可互操作性要求,使其成为真正的开放系统,在IEC标准,现场总线
通讯协议模型的用户层中,就明确规定用户层具有装置描述功能。为了实现互操作,每个现场总线装置
都用装置描述DD来描述。DD能够认为是装置的一个驱动器,它包括所有必要的参数描述和主站所需的操
作步骤。由于DD包括描述装置通信所需的所有信息,并且与主站无关,所以可以使现场装置实现真正的
互操作性。
实际情况是否如上述*,回答是否定的。目前通过的现场总线标准含8种类型,而原IEO
标准只是8种类型之一,与其它7种类型总线的地位是平等的。其它7种总线,不论其*有多少,每个总线协议都有一套软件、硬件的支撑。它们能够形成系统,形成产品,而原IEC现场总线标准,是一个既无软件支撑也无硬件支撑的空架子。所以,要实现某些总线的相互兼容和互操作,就目前状态而言,几乎是不可能的。
