Abnormality response message data structure:

Data order Name Byte

Byte0

Transaction identifier

High byte

Byte1 Low byte

Byte2

Protocol identifier

High byte

Byte3 Low byte

Byte4

Modbus data length

High byte

Byte5 Low byte

Byte6 Modbus ID Single byte

Byte7 0x80+ function code Single byte

Byte8 Abnormality response code Single byte

Note: How many bytes of data in response message depend on the read device address number in

DVP10MC11T in request message. So n value in Byte n in response message can be calculated through

reading device address number in DVP10MC11T.

 Example: To read the content of 0x1000 and 0x1001 address in DVP10MC11T

0x1000 and 0x1001 are the Modbus address of D0 and D1 in DVP10MC11T respectively. Suppose D0

value is 0x0100 and D1 is 0x0200.

Request message: “ 00 00 00 00 00 06 01 03 10 00 00 02”

Response message: “00 00 00 00 00 07 01 03 04 01 00 02 00”
