i have a jigsaw connected to a Modbus interface module MIM-B19N Samsung. I have the next parameters:
I attach the datasheet of this module to compare if you need: Manual Interface MODBUS Maquinas clima Samsung.pdf

I don't know if the problem is because of driver's parameters or firmware error. I will appreciate any help .

Hi Jose, I've got the same error, trying to communicate with an energy meter and replacing the modbus dongle solved the issue.
