Flame retardant cable, is refers to under specified test conditions, specimen was, after removed test of ignition, flame spread only in a limited range, residual sheep and burning in the finite cable to self extinguishing in the course of time. The fundamental characteristic is that it may burn out and not run in the case of fire, but it can spread fire. Generally speaking, in case of electric wire fire, it can be put in the local scope, not to produce spread, keep other kinds of e, avoid causing greater loss. The meaning of the flame retardant cable: under specified test conditions, samples were, in is removed after the fire, the spread of flame on the sample only in a limited range and the characteristic of self extinguishing, which has the ability of or delay the outbreak or spread of flame.

在自动化控制中plc编程是不可缺少的环节，我们怎样才能更好的学习这门技术呢。下面我给大家讲讲几点经验。编写位置控制指令尽可能用位置控制，不要使用相对指令。编写位置指令在每次启动瞬间或每次回到原点时，把当前位置清零。否则易产生位置和累计误差。当位置控制在回到原点时，要使用回原点指令，不要走数据。在编写数据转换时一定要有延时时间，因为机械设备不可能这么。手动和自动程序要分开写。在利用上升沿或下降沿的时候，触头编写要放在输出线圈的后面，否则不稳定或者扫描不到。
