BMS Li-ion battery via Modbus

[dusanstr]

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

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, 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.
