　　计算机屏蔽控制电缆一、产品特点及用途：用于连接电子计算机外围设备至生产现场，以及各种电器、仪表、自动装置等需要的屏蔽控制电缆。2.基本型号绝缘及护套材料还有YJ无卤低烟阻燃交联聚烯烃。金属屏蔽电力电缆适用于额定电压0．6／lkV及以下的电力线路中作输送电能用。

一帧为10位，1位起始位、8位数据位（先低后高）、1位停止位。波特率由T1或T2的溢出率确定。在发送或接收到一帧数据后，硬件置TI=1或RI=1，向CPU申请中断；但必须用软件清除中断标志，否则，下一帧数据无法发送或接收。发送：CPU执行一条写SBUF指令，启动了串行口发送，同时将1写入输出移位寄存器的第9位。发送起始位后，在每个移位脉冲的作用下，输出移位寄存器右移一位，左边移入0，在数据高位移到输出位时，原写入的第9位1的左边全是0，检测电路检测到这一条件后，使控制电路作后一次移位，/SEND和DATA无效，发送停止位，一帧结束，置TI=1。

6 kv and above cable joint: (1) installing a cable terminal head, must be stripped semiconductor electric shielding layer, operation shall not damage the insulation, should avoid mark uneven situation, when necessary use sand paper to grind; The shield end should be flat and the graphite layer (carbon particles) should be clean. (2) plastic cable end copper tape screened and armor must be good grounding, the short circuit also follow this principle, avoid unbalanced three-phase run ShiGang armoured end produce inductive electromotive force, and even "lighter" and sheath and other accidents. It is required to use my tinplate to braid copper wire for grounding lead. When connecting with the cable copper belt, it should be welded with chromium-iron tin. The shield of three-phase copper tape should be connected with ground wire respectively. Note that the shielded ground wire and steel armor ground wire should be separately drawn out and insulated from each other. The position of the welded ground wire should be as low as possible.

In order to improve the of the cable, we choose high electrical insulation materials production, such as special cable 1.8/3 kv frequency conversion motor, with 10 kv crosslinked insulating materials, special cable adopts frequency conversion motor of 6/10 kv, 35 kv crosslinking insulation materials, conductive shielding, insulation shield and insulation adopts the imported materials. In the process of production, we put special emphasis on the purification of raw materials, shielding closely with extruded insulation materials, control the uniformity of the insulation eccentricity and insulation outside diameter, which can reduce the interface effect, improve the electrical cable properties.

　　还可以使用更长的电缆，但是传输率要降低或使用中间放大器。目前，同轴电缆大量被光纤取代，但仍广泛应用于有线和无线电视和某些局域网。射频同轴电缆是指有两个同心导体，而导体和屏蔽层又共用同一轴心的电缆。目前，常用的射频同轴电缆有两类：50Ω和75Ω的射频同轴电缆。



　　在阻燃型系列产品中，成功地应用了隔氧技术，不仅0.6/1KV的聚氯乙烯绝缘和交联聚乙烯绝缘阻燃电力电缆能达到GB/T12666.5《成束电力电缆燃烧试验方法》中A类，而且额定电压6/10KV及8.7/15KV交联聚乙烯阻燃电力电缆也能达到A类高阻燃要求且有较大裕度。

　　阻燃通信电缆用途：主要用于传输音频、150kHZ及以下的模拟信号和2048kbit/s及以下的数字信号。在一定条件下，也可用于传输2048kbit/s以上的数字信号。适用于矿山、电厂、市内、近郊及局部地区。

也就是类似于三菱和台达系列中相当于SET/RERST指令；当置位接通一次后，对应的状态就保持，直到复位为ON时，解除保持；这样说大家应该明白吧。西门子S7-200PLC和S7-200smart里面，没有ALT指令，也没有KEEP指令，需要我们自己搭建一个一键启停梯形图。和（一张截图放不下，电脑屏比较小）图四当第一次按下按钮时候，网络1置位M0.0就导通了，网络2和网络3中M0.0常开点闭合，同时网络四接通Q0.0，同样，当第二次按下按钮时候，网络2的M0.1导通，同时网络3M0.0和M0.1导通，复位M0.0和M0.1线圈。
