描述

SPNIS21 工控PLC系统模块 现货

超时检测机械设备在各工步的动作所需的时间一般是不变的,即使变化也不会太大,因此可以以这些时间为参考,在PLC发出输出信号,相应的外部执行机构开始动作时启动一个定时器定时,定时器的设定值比正常情况下该动作的持续时间长20%左右。例如设某执行机构(如电动机)在正常情况下运行50s后,它驱动的部件使限位开关动作,发出动作结束信号。若该执行机构的动作时间超过60s(即对应定时器的设定时间),PLC还没有接收到动作结束信号,定时器延时接通的常开触点发出故障信号,该信号停止正常的循环程序,启动报警和故障显示程序,使操作人员和维修人员能迅速判别故障的种类,及时采取排除故障的措施。
逻辑错误检测在系统正常运行时,PLC的输入、输出信号和内部的信号(如辅助继电器的状态)相互之间存在着确定的关系,如出现异常的逻辑信号,则说明出现了故障。因此,可以编制一些常见故障的异常逻辑关系,一旦异常逻辑关系为ON状态,就应按故障处理。例如某机械运动过程中先后有两个限位开关动作,这两个信号不会同时为ON状态,若它们同时为ON,说明至少有一个限位开关被卡死,应停机进行处理。

主营:本特利,英维思,伍德沃德,福克斯波罗、西屋、瑞恩、施耐德莫迪康、ABB、AB、西门子、摩托罗拉、GE发那科、安川、博世力士乐,ACSO,力士乐等各大品牌的DCS系统配件,机器人系统配件,大型伺服系统备件。

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。
