有朋友问我,就是为什么他刚刚买回来的两个TL-PA101路由器或者两个TL-PA201路由器,发现路由器之间无法通信? 经过我的排查,发现路由器之间无法通信的原因可能有:设备设置不当、物理线路不稳定、受线路中某些电气器件影响等,具体排查步骤如下:
一、当设备发现线路中的另一个设备后,PLC灯会常亮,表示已经能相互通信。如果两个设备均接入后发现PLC灯不亮或者慢闪,可能的原因有以下几点:
(1)三相四线电路。在三相四线中,由于PLC设备工作原理以及三相四线电路的特性,可能会出现不同线路下的设备不能相互通信。
(2)网络名不相同。只有设备的网络名相同时,设备才能相互发现并通信。如果接在同一个插座上PLC灯仍然不亮,请安装光盘中的设备配置软件,通过配置软件分别将两个设备的网络名恢复到出厂网络名。
(3)空气开关的影响。请检查两个设备之间的线路是否存在空气开关,部分空气开关会导致设备无法相互通信。
(4)物理线路问题。请尝试把两个设备都插在同一个插座上,观察PLC灯能否常亮。
二、PWR灯为设备电源指示灯,正常情况下接入电源后应常亮,当发现PWR灯不亮时,请尝试更换插座接入,若多次更换后该指示灯仍然不亮,则可能是设备故障,需要进行检修。
三、请您确认设备均是接在同一个电表下。PLC产品只能在同一个电表下使用,不同电表下的设备不能相互通信。
要用到两个路由器,一般是单位、网吧或者公司大型网络搭建需要的,由于线路多、机器多,所以在用时一定要仔细细微。
