9199-00002 A6120 监测模块 进行接地支路检测

EMERSON 9199-00002 A6120 监测模块 持续模块 输入输出模块，绝缘监测模块，是针对直流系统正负极对地绝缘电阳达到告警整定值，发出接地告警信号，并进行接地支路检测，将接地故障定位在少数供电回路，以提高接地故障处理速度，减轻劳动，缩短接地周期，使电力系统运行更加安全能监测两段直流母线电压、正负母线对地电压，并显示。

能监测两段直流母线对地绝缘电阻，并显示正负母线对地绝缘电阻值。具有通讯(RS485)功能，4个RS485接口:可以通过通讯读取电压值、电阻值、SOE事件记录、修改时间及对时。每个RS485接口均有通讯状态指示灯 一红一绿，指示收发状态。开关状态量采集功能，能采集3路开关状态量。

用PLC进行网络设计难度比PLC单机控制大得多。首先应先用自己较熟悉的机型，对其基本指令和功能指令有较深入的了解，并且指令的执行速度和用户程序存储容量也应仔细了解。否则，不能适应实时要求，造成崩溃。另外，还要考虑通信接口、通信协议、数据传送速度等。zui后，还要向商家寻求网设计和软件技术支持及详细技术资料。在编制软件前，应首先熟悉所先用的PLC产品软件说明书。若用图形编程器或软件包，则可直接编程，若用手持编程器编程，应先画出梯形图后再编程。编程结束后先空调程序，待各个动作正常后，再在设备上调试。

EMERSON 9199-00002 A6120 Monitoring module Continuous module The input/output module and insulation monitoring module are used when the positive and negative electrodes of the DC system reach the alarm setting value, send a grounding alarm signal, detect the grounding branch, and locate the grounding fault in a few power supply circuits to improve the troubleshooting speed. Reduce labor, shorten the grounding period, make the power system more safe operation can monitor two sections of DC bus voltage, positive and negative bus voltage to ground, and display.

It can monitor the insulation resistance of two DC busbars to the ground and display the positive and negative insulation resistance of the busbar to the ground. With communication (RS485) function, 4 RS485 interfaces: can read the voltage value, resistance value, SOE event record, modify the time and time. Each RS485 port has a communication status indicator, one red and one green, indicating the sending and receiving status. The switch status quantity collection function can collect 3 switch status quantity.

It is much more difficult to use PLC for network design than PLC single machine control. First of all, you should first use your more familiar model, have a deeper understanding of its basic instructions and functional instructions, and the execution speed of instructions and user program storage capacity should also be carefully understood. Otherwise, it cannot meet the real-time requirements, resulting in a crash. In addition, also consider the communication interface, communication protocol, data transmission speed and so on. Finally, it is also necessary to seek network design and software technical support and detailed technical information from businesses. Before compiling the software, you should first be familiar with the PLC product software manual. If you use a graphic programmer or software package, you can program directly, if you use a handheld programmer programming, you should draw a ladder diagram before programming. After the programming is finished, the air conditioning program is first, and after each action is normal, it is debugged on the equipment.
