BMS Li-ion battery via Modbus - dusanstr - 07-09-2024
Hello, I want to ask you for help.
Via LK3, I load data from the BMS Li-ion battery via Modbus in the user settings. Everything works perfectly, I just have a problem with the display of the negative current when discharging the battery, it displays the positive value correctly.
Well thank you

Does anyone here use communication between LK3 and BMS of the accumulator via modbus?
Can anyone advise how to set LK3 so that it also correctly displays the minus value of the current?
Well thank you

wykryto błąd w odczycie wartości ujemnej na ModBusie... prawdopodobnie soft ją obrabia i zwraca modulo

Verify Modbus register settings and scaling factors in LK3. Use a Modbus diagnostic tool to confirm raw data, and update firmware if needed. Contact LK3 support if the issue persists.

Thanks for the answer.
I don't understand how to verify this " Check if the current value from the BMS is a signed integer and configure the LK3 to interpret it as such. Verify Modbus register settings and scaling factors in LK3. Use a Modbus diagnostic tool to confirm raw data "
My firmware is up to date, I have contacted LK3 support several times, but I haven't received any response.
Have a nice day.
