There is a difference in the modbus error handling when writing unimplemented registers or read-only registers.
In document "Sunspec Information Model Specification 1.9", these errors are just ignored, whereas in "SunSpec Device Information Model Specification 1.1" an exception 2, 3 or 4 must be returned.
Is it ok to implement only the newer behaviour - even for the 1xx models?
