RBR 760- IP Communication

Hi, have an energy meter from Accuenergy for monitoring and controlling my household battery. For communication, Modbus TCP/IP is used. The meter is connected via ethernet cable directly to the Orbi router with static IP. This works fine, and the meter can communicate and be read via the IP address through browser interfaces. But as soon as the communication is down, for example if you restart the meter or router, the communication stops. In the Orbi login, it still looks like the meter is online and the IP address is the same. But all communication has stopped. Via a web browser, you are only greeted with a message about ERR_CONNECTION_TIMED_OUT. Sometimes it is possible to plug the cable in and out, and the communication will come back. But not always. I have tried port forwarding without the problems ending. Does anyone know where the problem may lie?

    Hi need to update the case with some more information. After a little more research, I can see with the help of the Angry IP scanner that the meter loses connection and goes offline immediately after restarting the router or meter. I.e. the entire IP address is offline and cannot be reached or pinged. No communication via Modbus/IP. When I plug in and out of the cable, the device (usually) goes online again. No other wired devices have similar problems.

     

     

     

    Thanks

    What Firmware version is currently loaded?
    What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
    Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended. 

     

    What does static IP address mean? Did you configure a static IP address ON this particular device or did you set a IP address reservation on the RBR router? These are two different things. 

     

    Try swapping LAN cable between the RBR and this one device. CAT6 UTP is recommended. 

     

    Check with the Mfr of this device as well regarding there product.
