Exception Responses
The table below describes the exception codes along with their possible causes
| Code | Name | Meaning |
|---|---|---|
| 0lH | ILLEGAL FUNCTION | The function code received in the query is not an |
allowable action for the slave. If a Poll Program Complete command was issued, this code indicates that no program function
preceded it.
02H| ILLEGAL
DATA ADDRESS
| The data address received in the query is not an allowable address for the
slave.
03H| ILLEGAL DATA
VALUE
| A value contained in the query data field is not an allowable value for the
slave.
04H| SLAVE DEVICE
FAILURE
| An unrecoverable error occurred while the slave was attempting to perform the requested
action.
Available Modbus Function Codes
The table below describes implemented MODBUS functions
| Code | Original Modbus Function |
|---|---|
| 03H | Read Holding Registers |
| 10H | Write Multiple Registers |
Modbus Data Formats
16 bit Integer Values Values are stored in big-endian order per the MODBUS specification and consist of a single register. All integer values are documented a signed or unsigned. All signed values are represented using two’s-compliment.
Communication Example
The following tables contain the general command descriptions and example with Modbus RTU framing.
