EM1000 meter communication

Hi,

I checked the EM1000HLCD meter through the mod scanner. then it works properly. but another third-party monitoring system did not show data. what is the error?

Hello @JayangaDivya ,

There is not enough information to begin to answer this question. Almost all modbus requests are going to have a starting register X and a number of registers Y after that. Devices may behave different if using different starting registers or reading a size greater than Z. To do a true comparison you would need to know what the exact request, starting register and size, the third-party monitoring system sent to the device and make Mod Scanner send the exact same request. 

You also did not include details such as where Mod scanner was located relative to the 3rd party. Running on the same machine, verses different machines on same network verses different networks.  

 I am not EM1000 expert so I cannot speak to specifics of the meter. I can only speak about the generic troubleshooting.

Regards,

Charles

Hello @JayangaDivya ,

I cannot begin to pretend I can follow most of the screenshots. One thing that did stick out to me is Modscan used Swapped float while Niagara used float. Perhaps that is enough of a difference.
