When module receives correct command, it will make corresponding actions and send response back to the master. This is
successful communication.
5.6 、 C ommand for state collection of digital output :
Send: 01 01 00 00 00 04 3D C9 ( e xample/hexadecimal )
data

Receive: 01 01 01 03 11 89 ( e xample/hexadecimal )

1189
Converting reading data "03" to 2 hexadecimal results "0000 0011". From left to right, it represents the 4 digital output channel
status DI_04 ~ DI_01. Here it means DO_02 、 D O_01 have output but others no.
5.7 、 c ommand for module address setting :
Send : 0 0 06 00 64 00 01 08 04 ( e xample/hexadecimal )
date

0064
0001
0804
Receive : 0 0 06 00 64 00 01 08 04 ( e xample/hexadecimal )
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.
5.8 、 C ommand for communication parameter setting :
Send : 0 1 06 00 65 00 02 18 14 ( e xample/hexadecimal )
