plc能输入开关量，也就是一高一低的电平电压，而编码器脉冲信号，可以理解一定时间内，用极快的速度完成的一组开关量。
因为这种开关量的频率太高了，PLC的普通I/O口是无法准确读到这些脉冲的个数的，因为PLC工作过程中存在扫描周期，需要每个一段时间才去刷新一下普通I/O口的数据，而编码器的精度太高了，单位时间内输出的脉冲个数太多，普通I/O是无法胜任的。
一般PLC会设计有高速计数端口，本质是利用了底层单片机的硬件逻辑来完成这些编码器计数的，避开了扫描周期问题，PLC都设计有专门的高速计数指令，使用的时候，直接调用这些指令就可以读到当前的脉冲值了。

屏蔽对与屏蔽对具有较好的绝缘性能，电缆在使用中若屏蔽对屏蔽对之间出现电位差时，不会影响信号的传输质量。
用于以电子计算机为主的自动控制系统,尤其适用于计算机集散控制系统,传递生产装置过程变量的检测、控制、联锁、报警等模拟和数字信号。
RS485 wiring can be arbitrary layout into star connection with tree, 485 wiring specification is the wiring must be hand in hand, when there is no use 485 hub and 485 relay setting directly into the star connection and connection in a tree, it is easy to cause reflection bus no. Many contractor in 485 wiring, use of star connection and tree, sometimes the very, but sometimes is always appear problem, and it is difficult to find the reason, is usually caused by non-standard wiring. If star connection or tree connection is required due to field connection, the 485 hub and 485 relay of shenzhen fuyongtong technology co., LTD can be used to solve related problems.
此结构的屏蔽电缆可抗电磁感应、接地不良和电源线传导干扰，减小电感，防止感应电动势过大。
屏蔽层既起到抑制电磁波对外发射的作用，又可作为短路电流的通道，能起到中性线芯的保护作用。
6／10kV变频电机专用电缆，考虑到电缆在使用过程中经常受到径向外力作用，在电缆屏蔽层外增加镀锌钢带铠装层（在屏蔽层和钢带铠装层之间加隔离套）。

对于S7-1200V4.1以上版本，有6个动态连接资源可以用于HMI连接。
它们的最大HMI连接资源数可以达到18个。
对于之前的版本只能用预留的HMI连接资源用于HMI访问。
HMI设备占S7-1200的HMI连接资源个数基于WinCCTIAPortal的组态：注："资源数（默认）"是当HMI与S7-1200在一个项目中组态HMI连接时，会占用S7-1200的组态的HMI连接个数。

Mttest methods and determination rules for fire retardancy of fire retardant cables used in coal mines and Q/TX plastic insulation control cables used in coal mines.
???? In flame retardant series products, has been successfully used in the oxygen isolation technology, not only 0.6/1 kv polyvinyl chloride insulated and crosslinked polyethylene insulation flame retardant power cable can achieve GB/T12666.5 "into A bunch of power cable test" in class A, and rated voltage up to and including 6/10 kv 8.7/15 kv crosslinked poly (flame retardant power cable can reach A high class A demand and A large margin. On the basis of high flame retardant and high flame retardant cross-linked insulation, a low-smoke halogen-free high-flame retardant oxygen insulation layer power cable was added, and its low-smoke halogen-free performance was in line with GB/T17651.1.2 and GB/ t In this way, the overall level of the company's cross-linked power cable is lower than the domestic status. This company produces the type refractory power cables for rated voltage 0.6/1 kv copper core cable, can also produce low smoke zero halogen fire-resistant power cable, high flame retardant fire-resistant power cable oxygen insulation layer, the fire-resistant performance in line with the GB/T12666.6 cable fire resistance test. Therefore, the overall performance of refractory series power cables is good and reliable. The water resistance performance of fireproof cable conforms to iec 502-2.
