Reset counters through Modbus in metsepm5330

[MauroDiam]

Hello, is there a way to reset energy counter and max/min values through Modbus?

I searched the registers to do that in the modbus registers map , but I wasn't able to find them.

Hi @MauroDiam 

For PM5000 series, in order to send command through Modbus to perform registers reset like Min/Max values, please follow the steps in the following FAQ:
Procedure to send commands over Modbus to PM5000 using Modbus Tester
https://www.se.com/eg/en/faqs/FA241856/
- Read Command Semaphore value which is stored in Modbus register 5680(only perform the reading operation once or in the next 4 minutes)
- Set register Requested Command 5000 to the Command value 2009(Reset All Min/Max)
- Set register Command Semaphore 5001 to the Semaphore value retrieved in first step
- Then click on 'Write' button
