描述

AD202MW

 要提高现场输入给PLC信号的可靠性，首先要选择可靠性较高的变送器和各种开关，防止各种原因引起传送信号线短路、断路或接触不良。其次在程序设计时增加数字滤波程序，增加输入信号的可信性。
    在现场输入触点后加一定时器，定时时间根据触点抖动情况和系统要的响应速度确定，一般在几十ms，这样可保证触点确实稳定闭合后，才有其它响应。模拟信号滤波可采用图2b程序设计方法，对现场模拟信号连续采样3次，采样间隔由A/D转换速度和该模拟信号变化速率决定。3次采样数据分别存放在数据寄存器DT10、DT11、DT12中，当最后1次采样结束后利用数据比较、数据交换指令、数据段比较指令去掉最大和最小值，保留中间值作为本次采样结果存放在数据寄存器DT0中。
    提高读入PLC现场信号的可靠性还可利用控制系统自身特点，利用信号之间关系来判断信号的可信程度。如进行液位控制，由于储罐的尺寸是已知的，进液或出液的阀门开度和压力是已知的，在一定时间里罐内液体变化高度大约在什么范围是知道的，如果这时液位计送给PLC的数据和估算液位高度相差较大，判断可能是液位计故障，通过故障报警系统通知操作人员检查该液位计。又如各储罐有上下液位极限保护，当开关动作时发出信号给PLC，这个信号是否真实可靠，在程序设计时我们将这信号和该罐液位计信号对比，如果液位计读数也在极限位置，说明该信号是真实的；如果液位计读数不在极限位置，判断可能是液位极限开关故障或传送信号线路故障，同样通过报警系统通知操作人员处理该故障。由于在程序设计时采用了上述方法，大大提高了输入信号的可靠。

先介绍几点经验。
1、先通读一遍“系统手册”（不管能不能看懂，先了解个大概，以便学习编程时查找）；
2、由位控逻辑入手，逐渐增加定时、计数等条件，把或、与、非关系理顺；
3、进而练习整数运算、实数运算、类型转换；
4、量程转换、PID调节回路的建立及P、I、D参数的理解（最好是有个物理回路验证，比如变频器+电机+测速传感器）；
5、循环、顺序、跳转等程序控制（尽量避免跳转，非跳不可时也是跳的越近越好）；
6、中断、通讯、位置控制....

本人以ABB工业机器人配件DSQC系列和Motorola MVME系列，GE 卡件 模块 驱动器系列为主攻。各位电工朋友可根据自己的条件选择适合自己的PLC品牌，由于PLC的基本框架大同小异，学会一种至于其它的学习起来也就简单了。
