0x03 Read Holding Registers function | Toshiba IPE002Z instruction

E6581741

8.4. "03 (0x03) Read Holding Registers" function

The Modbus request is used to read the values of a number (No. of Points) of adjacent words starting at the address indicated (Starting Address). The values read are restored one after another, at the end of the response (First Point Data -> Last Point Data).

Request Format:

Byte

Meaning

0Function Code = 03h

1Starting Address Hi

2Starting Address Lo

3No. of Points Hi (0)

4No. of Points Lo (1 - 125)

Response format:

Byte

Meaning

0Function Code = 03h

1Byte Count (B = 2 × No. of Points)

2First Point Data Hi

3First Point Data Lo

･･･	････････････････

BLast Point Data Hi

B+1 Last Point Data Lo

Exception response format:

Byte

Meaning

0Function Code = 83h Exception Code =

101 (Illegal Function)

02 (Illegal Data Address)

03 (Illegal Data Value)

Notes

If the communication number that doesn't exist is read, the option returns 0x8000.
