Electronic computer shielded cable, choose high pressure polyethylene insulation, small dielectric constant use to ground, and the screen, the total screen (or three quad twisted, group screening, group screen a total screen), such as structure, with a small dielectric loss, transmit ability strong, good anti-jamming performance characteristics, can be reliably transmitted weak the analog signal or digital signal, can be widely used in electricity, metallurgy, petroleum, chemical, textile and other departments of detection and control computer system or automated devices, as well as general industrial computer. High-temperature F46 computer cable belong to one of the special cable, electronic computer system is in urgent need of modern industrial construction of form a complete set of products, it is widely used in energy industry, metallurgical industry and petrochemical industry and other industrial enterprises and scientific research department of the electronic computer, instruments and meters, all kinds of automatic detection e, and other information processing e signalling and the control system. Application: it is installed in indoor, cable trench, pipe and other places where high temperature resistance electrostatic shielding is required

HB型步进电机的定子有槽，线圈为集中方式，为达到机械绕线的目的，绝缘构造也加以改进。以图左为例，日本伺服(股份)公司用的槽绝缘插入绕线的定子，绕线如右图所示。该方式如上左图所示，定子铁心厚度为电机厚度的1/2，用裙状绝缘材料插人槽中，铁心槽侧面全部被树脂覆盖,利用绕线机的梭子牵引线机械绕制，线圈一个端点固定在接线柱上，另一端连接固定后从引出线出口引出。用此方法，电机定子与引出线部分可分开生产，便于部件标准化。

Flame-retardant cable: the electric wire and cable are produced by external heating. In order to achieve the purpose of flame retardant, the three elements must be caused, namely, combustible gas, heat and oxygen. Therefore, generally USES is added in the sheath material containing halogen halide and metal oxide, from the perspective of flame retardant, that's very good, but, because of the halide is contained in these materials, in a lot of smoke and released when halogenated body, so, the low visibility when fire, bring a lot of personnel evacuation and fire obstruction, whereas people more for functioning suffocated to death.

PLC与PLC之间的通信。通信的基本类型：并行通信与串行通信并行通信:是将一个数据的每一个二进制位，均采用单独的导线进行传输，并将发送与接收方进行并行连接；如下图所示串行通信：是通过一对连接导线，将发送与接收方进行连接，传输数据的每一个二进制位，按规定的顺序，在同一连接导线上，依次进行发送与接收。如下图所示：PLC的通信一般都是用串行通信。标准串行接口用于通信线路连接的输入/输出线路称为接口。连接并行通信线路的称谓并行接口；连接串行通信线路的称谓串行接口。
