bjarni Posted October 2, 2019 Report Share Posted October 2, 2019 Hello, I'm trying to poll some values from Laumas weight transmitter - and I'm kind of stuck. I've tried to read some addresses according to the Laumas manual, but the power-up value in the receiving variable is never overwritten. I get modbus status as -11, which I don't know what means. THe setup: It should be reading all the time if set up as periodic and the active bit is set ? The values when running: Anybody with any hints for me? Thanks, Bjarni Link to comment Share on other sites More sharing options...

Gabriel Franco Posted October 3, 2019 Report Share Posted October 3, 2019 Use address 8 and 9 to read Net weight high and low bytes. Tags should be INT16. Link to comment Share on other sites More sharing options...
