I am learning Modbus and having a issue writing some code to write a value to a specified register where I also need to write the 1's complement in the same write. This isto a Deep Sea Electronics Governor module. I have to set the module to AUTO by writing 1 to register 35701 and in teh same write also write 1 to the 1's complement at 29834. The writevar command works only with sequential addresses so that leaves me stuck.
Hoping somebody can let me know how its done in Unity Pro.
