PLc/Dcsc及安全 网络的优点包括:

1机械控制更大的集成性和灵活性

2当标准控制层智能化时，能够进行更好更容易的故障诊断入

3更快、更方便的维护

4 减少安装、调试以及重新配置的费用5与对于逻辑单独使用安全相比，降低了设计和硬件成本和l/0线应分别配线，隔离变压器与PLC和l/0之间应采用双绞线连接。将PLC的Il/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。

Advantages of PLc/Dcsc and security network include:

1 Mechanical control for greater integration and flexibility

2 When the standard control layer is intelligent, better and easier fault diagnosis can be carried out

3 Faster and more convenient maintenance

4 Reduce installation, commissioning and reconfiguration costs 5 Compared with the safety of logic alone, the design and hardware costs are reduced and the l/0 line should be wired separately, and the isolation transformer should be connected to the PLC and l/0 by twisted pair. The PLC Il/O line and the high-power line are separated, such as the xu in the same yi line slot, separate and bundle the AC line, DC line, if conditions permit, the groove is the best, which can not only make it have as large a space distance as possible, and can reduce the interference to the minimum.

PLC should be away from strong interference sources such as welding machines, high-power silicon rectifier devices and large power equipment, and can not be installed in the same switch cabinet with gao voltage appliances. In the cabinet, the PLC should be far away from the power line (the distance between the two should be greater than 200 mm). The inductive load installed in the same cabinet with the PLC, such as the relay with large power and the coil of the contactor, should be connected to the RC arc suppression circuit.
