Solutions to the inability of two tl-pa201 routers to communicate
After my investigation, found that routers can not communicate between the reasons may be: improper equipment settings, physical circuit instability, affected by certain electrical devices in the circuit, the specific procedures are as follows:
One, when the equipment found in the line of another device, the PLC lantern Festival is often bright, said already can communicate with each other. If the two devices are connected to find that the PLC light is not bright or slow flash, there are several possible reasons for the following:
(1) Three-phase four-wire circuit. In the three-phase four line, due to the operating principle of plc and the characteristics of three-phase four-wire circuit, it may appear that the equipment under different circuits cannot communicate with each other.
(2) The network name is not the same. Devices can discover and communicate with each other only if the network name of the device is the same. If the PLC lamp is still not lit on the same socket, install the device configuration software on the CD and restore the network name of two devices to the factory network name by configuring the software.
(3) The influence of the air switch. Please check if there is an air switch between the two devices and some air switches will cause the device to not communicate with each other.
(4) Physical wiring problems. Please try to plug all two devices into the same socket and see if the PLC light is always bright.
Second, the PWR lamp for the equipment power indicator, under normal circumstances should be illuminated steady after the power supply, when found that PWR light is not lit, please try to replace the socket access, if the light is still not bright after multiple replacement, it may be the equipment failure, the need for maintenance.
Please confirm that the equipment is connected to the same meter. PLC products can only be used under the same meter, different meters of equipment can not communicate with each other.
To use two routers, usually units, internet cafes or companies to build a large network needs, due to many lines, more machines, so you must carefully detail.
