系统设的工作量小，维护方便，容易改造

　　(1) 设计与维护

　　PLC用存储逻辑代替接线逻辑，大大减少了控制设备外部的接线，使控制系统设计及建造的周期大为缩短，同时日常维护也变得容易起来，更重要的是使同yi设备经过改变程序而改变生产过程成为可能。特别适合多品种、小批量的生产场合。

　　(2) 安装与布线

　　动力线、控制线以及PLC的电源线。

　　电源线是用作电气组件或设备与电源的连接线，通常来说指电线与其yi端连接的插头或尾插的集合体，是电器产品的基本零部件之yi。电源线分为电线和插头两部分。

       和I／O线应分别配线，隔离变压器与PLC和I／O之间应采用双绞线连接。将PLC的I／O线和大功率线分开走线，如必xu在同yi线槽内，分开捆扎交流线、直流线，若条件允许，分槽走线zui好，这不仅能使其有尽可能大的空间距离，并能将干扰降到zui低限度。

　　PLC应远离强干扰源如电焊机、大功率硅整流装置和大型动力设备，不能与gao压电器安装在同yi个开关柜内。在柜内PLC应远离动力线(二者之间距离应大于200 mm)。与PLC装在同yi个柜子内的电感性负载，如功率较大的继电器、接触器的线圈，应并联RC消弧电路。

　　PLC的输入与输出zui好采用分开走线，开关量与模拟量也要分开敷设。模拟量信号的传送应采用屏蔽线，屏蔽层应yi端或两端接地，接地电阻

　　电阻，物质对电流的阻碍作用就叫该物质的电阻。电阻小的物质称为电导体，简称导体。电阻大的物质称为电绝缘体，简称绝缘体。 应小于屏蔽层电阻的1／10。

　　交流输出线和直流输出线不要用同yi根电缆，输出线应尽量远离gao压线和动力线，避免并行。

　　电缆是yi种用以传输电能信息和实现电磁能转换的线材产品。既有导体和绝缘层，有时还加有防止水份侵入的严密内护层，或还加机械强度大的外护层，结构较为复杂，截面积较大的产品叫做电缆。

The workload of system design is small, easy to maintain, and easy to modify

(1) Design and Maintenance

PLC replaces wiring logic with storage logic, greatly reducing the external wiring of control equipment, greatly shortening the design and construction cycle of the control system, making daily maintenance easier, and more importantly, making it possible for the same equipment to change the production process through program changes. Especially suitable for multi variety and small batch production occasions.

(2) Installation and wiring

Power lines, control lines, and PLC power lines.

A power cord is used as a connecting wire between electrical components or equipment and a power source. Generally speaking, it refers to the collection of plugs or tail plugs that connect the wire to its end, and is one of the basic components of electrical products. The power cord is divided into two parts: wires and plugs.

The and I/O lines should be wired separately, and the isolation transformer should be connected to the PLC and I/O using twisted pair cables. Separate the I/O lines and high-power lines of the PLC from each other. If necessary, bundle the AC and DC lines separately in the same trunking. If conditions permit, divide the trunking and route them well. This not only allows for maximum space distance, but also reduces interference to a minimum.

PLC should be kept away from strong interference sources such as welding machines, high-power silicon rectifier devices, and large power equipment, and should not be installed in the same switchgear as any other piezoelectric devices. The PLC inside the cabinet should be kept away from the power line (the distance between the two should be greater than 200 mm). Inductive loads installed in the same cabinet as PLCs, such as high-power relays and contactor coils, should be connected in parallel with RC arc suppression circuits.

The input and output of PLC should be wired separately, and the switching and analog quantities should also be laid separately. The transmission of analog signals should use shielded wires, and the shielding layer should be grounded at one or both ends, with a grounding resistance

The resistance of a substance to an electric current is called its resistance. Substances with low resistance are called electrical conductors, abbreviated as conductors. Substances with high resistance are called electrical insulators, abbreviated as insulators. It should be less than 1/10 of the shielding layer resistance.

Do not use the same cable as the AC output line and DC output line. The output line should be as far away from the voltage line and power line as possible to avoid parallelism.

Cable is a wire product used to transmit electrical energy information and achieve electromagnetic energy conversion. A product with a complex structure and a large cross-sectional area is called a cable, which includes both a conductor and insulation layer, and sometimes a tight inner protective layer to prevent water intrusion, or an outer protective layer with high mechanical strength.
