NI4-M12-RP6X-H1141流量计
可编程控制器(programmable logical controller,简称PLC)已经越来越多地应用于工业控制系统中,并且在自动控制系统中起着重要的作用。所以,对PLC的正确选择是重要的。
面对众多生产厂家的各种类型PLC,它们各有优缺点,能够满足用户的各种需求,但在形态、组成、功能、网络、编程等方面各不相容,没有一个统一的标准,无法进行横向比较。下面提出在自动控制系统设计中对PLC选型的一些看法,可以在挑选PLC时作为参考。
可以通过以下几方面的比较,挑选到适合的产品。
这一点尤为重要。在自动控制系统设计之初,就应该对控制点数(数字量及模拟量)有一个准确的统计,这往往是选择PLC的条件,一般选择比控制点数多10%~30%的PLC。这有几方面的考虑:
1、可以弥补设计过程中遗漏的点;
2、能够保证在运行过程中个别点有故障时,可以有替代点;
3、将来增加点数的需要。
工作环境是PLC工作的硬性指标。自控系统将人们从繁忙的工作和恶劣的环境中解脱出来,就要求自控系统能够适应复杂的环境,诸如温度、湿度、噪音、信号、工作电压等,各款PLC不尽相同。要选择适应实际工作环境的产品。
