When module receives correct command, it will make corresponding actions and send response back to the master. This is
successful communication.

This command means to send a code to a module, set the module address as 01, this setting could be saved when power off;
default address of module is 01,each module address could be assigned separately when using multiple modules for
network.Attentions is required that only one module could be used in 485 network when using multiple address sending,
otherwise all the modules will share the same address in 485 network. When module receives correct command, it will make
corresponding actions and send response back to the master. This is successful communication.
