在典型的工厂安装中可能会遇到布线:1.电源布线–工厂配电和高功率负载,如高马力电机。在220 VAC或更高电压下,这些电路的额定值可能从几十到数千KVA不等。2.控制接线–通常为低电压DC或120 VAC,额定能量有限。例如启动/停止开关、接触器线圈和机器限位开关的接线。这通常是离散I/O的接口级别。3.模拟接线–传感器输出和模拟控制电压。这是I/O模拟块的接口级别。4.通信和信号布线–将一切连接在一起的通信网络,包括计算机局域网、MAP、Profibus和Genius总线。这四种类型的接线应尽可能分开,以减少绝缘故障、错误接线和信号之间的相互作用(噪声)带来的危险。典型的PLC系统可能需要后三种接线的混合,尤其是在电机控制中心和控制面板上的狭窄区域。一般来说,可以将通信总线电缆与模块的I/O布线以及相关控制级布线混合使用。所有噪声拾取都是累积的,这取决于导线之间的间距和它们一起运行的距离跨度。wiring may be encountered in a typical factory installation: 1. Power wiring – the plant power distribution, and high power loads such as high horsepower motors. These circuits may be rated from tens to thousands of KVA at 220 VAC or higher. 2. Control wiring – usually either low voltage DC or 120 VAC of limited energy rating. Examples are wiring to start/stop switches, contactor coils, and machine limit switches. This is generally the interface level of discrete I/O. 3. Analog wiring – transducer outputs and analog control voltages. This is the interface level to I/O analog blocks. 4. Communications and signal wiring – the communications network that ties everything together, including computer LANs, MAP, and Profibus and Genius busses. These four types of wiring should be separated as much as possible to reduce the hazards from insulation failure, miswiring, and interaction (noise) between signals. A typical PLC system may require some mixing of the latter three types of wiring, particularly in cramped areas inside motor control centers and on control panels. In general, it is acceptable to mix the communications bus cable with the I/O wiring from the blocks, as well as associated control level wiring. All noise pickup is cumulative, depending on both the spacing between wires, and the distance span they run together.
