CJ-series User Defined CAN Unit Operation Manual for NJ-series CPU Unit (W517)
Note 1
On response code 0000, the unit configures the input (receive) message buffer identified with
buffer number with the following properties:
•
Extended identifier length (see additional information below)
•
Identifier number
•
Big or little endian format, see
Additional Information
The last command 2905 or 2906 sent to the unit determines whether 11-bit or 29-bit identifiers
are used for all input message buffers. If the last command is 2905, 11-bit identifiers will be used.
If the last command is 2906, 29- bit identifiers will be used.
Each Input (Receive) Buffer requires the following settings that are configured using the command
code 2906.
•
the 29-bit identifier
•
the use of little endian or big endian
The following table defines the minimum and maximum values for each item in the command block with
setting details.
Issuing a Configure 29-Bit ID Input (Receive) Message Buffer command will result in the following
response End Codes.
