  S7-300 PLC的选型原则是据生产工艺所需的功能和容量进行选型,并考虑维护的方便性、备件的通用性,以及是否易于扩展和有无特殊功能等要求。选型时具体注意以下几方面:

  (1)有关参数确定。一是输入/输出点数(I/O点数)确定。这是确定PLC规模的一个重要依据,一定要根据实际情况留出适当余量和扩展余地。二是PLC存储容量确定。注意当系统有模拟量信号存在或要进行大量数据处理时,其存储容量应选大一些。

  (2)系统软硬件选择。一是扩展方式选择,S7-300 PLC有多种扩展方式,实际选用时,可通过控制系统接口模块扩展机架、Profibus-DP现场总线、通信模块、运程I/O及PLC子站等多种方式来扩展PLC或预留扩展口;二是PLC的联网,包括PLC与计算机联网和PLC之间相互联网两种方式。因S7-300 PLC的工业通信网络淡化了PLC与DCS的界限,联网的解决方案很多,用户可根据企业的要求选用;三是CPU的选择,CPU的选型是合理配置系统资源的关键,选择时必须根据控制系统对CPU的要求(包括系统集成功能、程序块数量限制、各种位资源、MPI接口能力、是否有

  PROFIBUS-DP主从接口、RAM容量、温度范围等),并最好在西门子公司的技术支持下进行,以获得合理的选型;四是编程软件的选择,这主要考虑对CPU的支持状况,我们的体会是:STEP7 V4.0对有些型号的CPU不支持,硬件组态时会发生故障出错,而STEP7V5.0则不存在这种问题。 Applied Materials/AMAT 0200-09478 Plate gas distr. uppe
