hi i am new in this forum your information help me to much, but i need read active energy how i can read this?

yes i do this yet, but my problem is when i read this register dont match with the active energy of the display of the sentron pac, what i need to do for the register and the display values are equal

greetings

Hello mcalix.
It's very strange!
Please perform the following checks and feed back me here again:

1. Please make a check on the ratios of current transformer you are using. These ratios should be entered correctlly in the Sentron PAC 3200 parameters.
2. Also check the voltage transformer ration if exist.
3. Now check that the voltage of Phase 1, is connected to V1 of PAC 3200 and the output of current transformer of phase 1 is connected to IL1l & IL1k. and check the direction of it (l & k).
check them for the remaining two phases. It's too important.

I was doing a project two years ago using power meters SIMEAS P. And during commissioning, they have connected for instance, current transformer of phase 1 into current inputs of phase 3. And voltage of phase 1 into voltage input of phase 1. so the meters was measuring wrong values for power, energy and power factor.

But I am still seeing that your problem is strange. as you said that the meter reads values and sends different values to the master CPU!

Can you please tell me what's the status for power factor and power? Does it sends the correct data?
Also tell me: To what extent the data is different in active power?
i.e if the load is disconnected, what would happen on both the Sentron display and in the master CPU?
Before,the loadto beconnected again: take the readings of both Sentron display and the CPU.
And then re-connect the load again to certain period.
Then disconnect it again.
Take readings now. Claculate the difference and see if the energy has been incremented in a correct way or not. As may be the Sentron and WinCC readings of energy require to be resetted.

thanks for your help i atached the pictures in them you can see the problem i need solve this problem right now please helpme, all the values are ok only the active energy and reactive energy are wrong.

New question published by newbond007 is split to a separate thread with the subject Sentron PAC3200, reading total kilowatt.
