描述

IMMPI01

在PLC控制系统中,电源占有极重要的地位。电网干扰串入PLC控制系统主要通过PLC系统的供电电源(如CPU电源、I/O电源等)、变送器供电电源和与PLC系统具有直接电气连接的仪表供电电源等耦合进入的。现在对于PLC系统供电的电源,一般都采用隔离性能较好的电源,而对于变送器供电电源以及和PLC系统有直接电气连接的仪表供电电源,并没受到足够的重视。虽然采取了一定的隔离措施,但普遍还不够,主要是使用的隔离变压器分布参数大,抑制干扰能力差,经电源耦合而串入共模干扰、差模干扰。所以对于变送器和共用信号仪表供电应选择分布电容小、抑制带大(如采用多次隔离和屏蔽及漏感技术)的配电器,以减少PLC系统的干扰。
此外,为保证电网馈电不中断,可采用在线式不间断供电电源(UPS)供电,提高供电的安全可靠性。而且UPS还具有较强的干扰隔离性能,是一种PLC控制系统的理想电源。

接地的目的通常有两个,一为了安全,二是为了抑制干扰。完善的接地系统是PLC控制系统抗电磁干扰的重要措施之一。
系统接地有浮地、直接接地和电容接地三种方式。对PLC控制系统而言,它属高速低电平控制装置,应采用直接接地方式。由于信号电缆分布电容和输入装置滤波等的影响,装置之间的信号交换频率一般都低于1MHz,所以PLC控制系统接地线采用一点接地和串联一点接地方式。集中布置的PLC系统适于并联一点接地方式,各装置的柜体中心接地点以单独的接地线引向接地极。如果装置间距较大,应采用串联一点接地方式,用一根大截面铜母线(或绝缘电缆)连接各装置的柜体中心接地点,然后将接地母线直接连接接地极。接地线采用截面大于22mm2的铜导线,总母线使用截面大于60mm2的铜排。接地极的接地电阻小于2Ω,接地极最好埋在距建筑物10~15m远处,而且PLC系统接地点必须与强电设备接地点相距10m以上。信号源接地时,屏蔽层应在信号侧接地;不接地时,应在PLC侧接地;信号线中间有接头时,屏蔽层应牢固连接并进行绝缘处理,一定要避免多点接地。多个测点信号的屏蔽双绞线与多芯对绞总屏蔽电缆连接时,各屏蔽层应相互连接好,并经绝缘处理,选择适当的接地处单点接地。

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。
