     虽然不同品牌PLC产品相差无几,但并不代表用不同的品牌的东西可以掉以轻心。相对于某些由三菱PLC应用转到西门子PLC应用中的用户来说,在接触及使用的初期,更加应该从使用、保养、储存等最基础的地方入手,才可以把应用技巧发挥到最极致。下面是关于如何保养西门子PLC的相关事项。
    首先,应该养成定期清洗的习惯,电源机架下方过滤网每三个月更换下,每六个月或季度对PLC进行清扫。
    其次,在检修时候,应该注意以下事项:
    (1)测量电压时,要用数字电压表或精度为1%的万能表测量
    (2)电源机架,CPU主板都只能在主电源切断时取下;
    (3)在RAM模块从CPU取下或插入CPU之前,要断开PC的电源,这样才能保证数据不混乱;
    (4)在取下RAM模块之前,检查一下模块电池是否正常工作,如果电池故障灯亮时取下模块PAM内容将丢失;
    (5)输入/输出板取下前也应先关掉总电源,但如果生产需要时I/0板也可在可编程控制器运行时取下,但CPU板上的QVZ(超时)灯亮;
    (6)拨插模板时,要格外小心,轻拿轻放,并运离产生静电的物品;
    (7)更换元件不得带电操作;
    (8)检修后模板安装一定要安插到位。
