PLC控制系统设计时应遵循的主要步骤和内容
(1)工艺分析
深入了解控制对象的工艺过程、工作特点、控制要求,并划分控制的各个阶段,归纳各个阶段的特点,和各阶段之间的转换条件,画出控制流程图或功能流程图。
(2)选择合适的PLC类型
在选择PLC机型时,主要考虑下面几点:
1功能的选择。对于小型的PLC主要考虑I/O扩展模块、A/D与D/A模块以及指令功能(如中断、PID等)。
2I/O点数的确定。统计被控制系统的开关量、模拟量的I/O点数,并考虑以后的扩充(一般加上10%~20%的备用量),从而选择PLC的I/O点数和输出规格。
3内存的估算。用户程序所需的内存容量主要与系统的I/O点数、控制要求、程序结构长短等因素有关。一般可按下式估算:存储容量=开关量输入点数×10+开关量输出点数×8+模拟通道数×100+定时器/计数器数量×2+通信接口个数×300+备用量。
(3)分配I/O点。分配PLC的输入/输出点,编写输入/输出分配表或画出输入/输出端子的接线图,接着就可以进行PLC程序设计,同时进行控制柜或操作台的设计和现场施工。
(4)程序设计。对于较复杂的控制系统,根据生产工艺要求,画出控制流程图或功能流程图,然后设计出梯形图,再根据梯形图编写语句表程序清单,对程序进行模拟调试和修改,直到满足控制要求为止。
(5)控制柜或操作台的设计和现场施工。设计控制柜及操作台的电器布置图及安装接线图;设计控制系统各部分的电气互锁图;根据图纸进行现场接线,并检查。
(6)应用系统整体调试。如果控制系统由几个部分组成,则应先作局部调试,然后再进行整体调试;如果控制程序的步序较多,则可先进行分段调试,然后连接起来总调。
(7)编制技术文件。技术文件应包括:可编程控制器的外部接线图等电气图纸,电器布置图,电器元件明细表,顺序功能图,带注释的梯形图和说明。
