除了上述注意事项之外,还有其它注意事项要留意。
首先比较重要的是静电的隔离。静电是无形的杀手,但可能因为不会对人造成生命危险,所以许多人常常忽视它。在中国的北方、干燥的场所,人体身上的静电都是造成静电损坏电子组件的因素。虽然你被静电打到的话,只不过是轻微的酥麻,但这对PLC和其它任何电子器件就足以致命了。
要避免静电的冲击有下列三种方式:在进行维修或更换组件时,请先碰触接地的金属,以去除身上的静电;不要碰触电路板上的接头或是IC接脚;电子组件不使用时,请用有隔离静电的包装物,将组件放置在里面。想象PLC里的元器件是一个娇嫩的婴儿,而那些静电会导致这个婴儿死亡,你就会更容易以正确的态度对待这个问题了。
基座安装(RACK)时,在决定控制箱内各种控制组件及线槽位置后,要依照图纸所示尺寸,标定孔位,钻孔后将固定螺丝旋紧到基座牢固为止。在装上电源供应模块前,必须同时注意电源线上的接地端有无与金属机壳连结,若无则须接上。接地不好的话,会导致一系列的问题,静电、浪涌、外干扰,等等。由于不接地,往往PLC也能够工作,因此,不少经验不足的工程师就误以为接地不那么重要了。这就像登山的时候,没有系上保护缆绳一样,虽然你正常前进的时候,保护缆绳没有任何作用,但一旦你失足的时候,没有那根绳子,你的生命就完结了。PLC的接地,就相当于给PLC系上保护缆绳。
在I/O模块安装时,须注意如下事项:I/O模块插入机架上的槽位前,要先确认模块是否为自己所预先设计的模块;I/O模块在插入机架上的导槽时,务必插到底,以确保各接触点是紧密结合的;模块固定螺丝务必锁紧;接线端子排插入后,其上下螺丝必须旋紧。由于现场的变压器、电机等影响,多少会有振动,如果这些螺丝钉松动了,会导致模块从机架中松开。
