1，编程语言plc的编程方式有这么几个，梯形图语言(LD)、指令表语言（IL）、功能模块图语言(FBD)、顺序功能流程图语言(SFC)、结构化文本语言(ST)。其中梯形图类似于继电器电路，被电气控制人员广泛接纳，新手推荐采用梯形图进行编程，而单片机的编程语言，我记得在大学时书上是用汇编语言吧，各种指令代码真看的痛不欲生啊，后边接触C语言了还好些，跑马灯程序的还隐约记得，相比于plc单片机的编程要更难一些尤其越到后面越难，需要计算机基础会更好一点。

　　成缆工序变频电缆要求结构对称，成缆时必须保证绝缘线芯张力均匀，使成缆后的线芯长度尽量保持一致，否则会引起结构变化，导致电容和电感的不均匀性，影响电缆的电气性能*1*名称：充油通信电缆*2*型号：HYAT、HYAT53、HYAT23、HYAT22（防水、地埋）*3*用途：实心绝缘填充型电缆适用于本地电。
　　 对电缆端头和中间接头的基本要求：a.导体连接好；b.绝缘可靠，推荐采用辐照交联热收缩型硅橡胶绝缘材料；c.密封良好；d.足够的机械强度，能适应各种运行条件。 电缆端头必须使用防止水及其它腐蚀性材料的侵蚀，以防因水树引起绝缘层老化而导致击穿。

Precautions for installation of power cables: keep 2m distance when the cable is installed in parallel with the thermal pipe, and 0.5m should be maintained when crossing. The cable shall be installed at a distance of 0.5m in parallel or across other pipelines. When the cable is directly buried and installed, the direct buried depth of 1-35kv cable is less than 0.7m. When 10KV and below cables are installed in parallel, the net distance between them shall not be less than 0.1m and 10-35kv shall not be less than 0.25m. The distance of cross installation is not less than 0.5m. Cable laying temperature lower than 0 ℃, bending radius: multi-core cable or 15 (D + D), a single cable 20 or more (D + D), (D for cable diameter, D) for the conductor diameter. ? 6KV and above cable connector:? When installing the terminal head of the cable, the semiconductor electrical shielding layer must be stripped off. During operation, the insulation shall not be damaged. 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. Basic re for cable terminals and intermediate joints: a. good conductor connection; B. The insulation is reliable, and it is recommended to use irradiated cross-linked heat-shrinkable silicone rubber insulation materials; C. good sealing; D. sufficient mechanical strength to meet various operating conditions. The end of the cable must be used to prevent water and other corrosive materials from corroding, in order to prevent the water tree caused by the aging of the insulation layer and breakdown. Crane or forklift should be used for the loading and unloading of cables. It is forbidden to run flat or lay flat. For installation of large cables, cable laying cart should be used to avoid external damage or abrasion caused by manual dragging. If the cable cannot be laid in time for some reason, it should be stored in a dry place to prevent sunlight from exploding and water entering the end of the cable. ? Note: the installation of wire and cable should be familiar with the performance of wire and cable installation personnel or full-time technical personnel, if there are still unclear matters, ball related technical department or technical department of our factory.
