Diagnostics
The function codes provided for all the modules are a subset of the "Public Function
Codes", validated by the Modbus-IDA Organization.
Function 01 and Function 02 can be used to read both digital output and digital input.
Function 03 and Function 04 can be used to read both output and input registers.
MODBUS Exception Responses:
Code Name Meaning
01 ILLEGAL FUNCTION The function code received in the query is not an
allowable action for the server (or slave)
02 ILLEGAL DATA The data address received in the query is not an
ADDRESS allowable address for the server (or slave).
03 ILLEGAL DATA A value contained in the query data field is not an
VALUE allowable value for server (or slave)
07 NEGATIVE The server (or slave) is in the wrong state to process
ACKNOWLEDGE a request of this type or an attempt to write to a read
- NAK only address has been made
Code 07 has not been provided by Modbus.org Protocol. Use it for ASCON products com-
patibility only.
