 S3 is DeviceNet service code:
Service code
Explanation
0x01
Get all attributes (Get_Attribute_All)
0x02
Set all attributes (Set_Attribute_All)
0x0E
Get one single attribute (Get_Attribute_Single)
0x10
Set one single attribute (Set_Attribute_Single)
 S4, S5 and S6 represent Class ID, Instance ID and Attribute ID respectively.
 S7 is the written-data size with the unit: Byte.
 S8 is the start device where written data are stored. The data are arranged in the order from low byte to high
byte.
 S9 is the communication timeout time within the range: 1~100 and with the unit: 0.1 second.
 S10 is the times of re-transmission within the range: 0~3. When communication timeout occurs, the
communication will be resent
 D3 represents the error codes to read and write.
