PLC机型选择的基本原则是在满足功能要求及保证可靠、维护方便的前提下,力争最佳的性能价格比。选择时主要考虑以下几点:

(一)合理的结构型式

PLC主要有整体式和模块式两种结构型式。

整体式PLC的每一个I/O点的平均价格比模块式的便宜,且体积相对较小,一般用于系统工艺过程较为固定的小型控制系统中;而模块式PLC的功能扩展灵活方便,在I/O点数、输入点数与输出点数的比例、I/O模块的种类等方面选择余地大,且维修方便,一般于较复杂的控制系统。

(二)安装方式的选择

PLC系统的安装方式分为集中式、远程I/O式以及多台PLC联网的分布式。

集中式不需要设置驱动远程I/O硬件,系统反应快、成本低;远程I/O式适用于大型系统,系统的装置分布范围很广,远程I/O可以分散安装在现场装置附近,连线短,但需要增设驱动器和远程I/O电源;多台PLC联网的分布式适用于多台设备分别独立控制,又要相互联系的场合,可以选用小型PLC,但必须要附加通讯模块。NIB ASHCROFT 35-1009-SWL-02B-200-XFF GLYCERIN PRESSURE GAUGE 0-200PSI 3 1/2"
