-bit ID CAN Message (2
907)
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.
The instruction is used to transmit a user defined CAN message. This function is only for advanced
users that have knowledge of the message structure of the higher layer protocol. The User Defined
CAN Unit will not check the validity of the CAN message.
End Code (hex)

Normal completion
Unit state = ST4 or ST5 and
all parameters are in range
Command is executed and
operation is normal.
1001
Command length exceeds
maximum command
length
---
Too many parameters sent in
the command.
Correct the command and re-
send.
1002
The command length is
insufficient for the smallest
command
---
Too few parameters sent in
the command.
Correct the command and re-
send.
1103
Address range destination
error
Unit state = ST4 or ST5 and
buffer number is greater than
or equal to the number of
input buffers configured with
command 2902
Number of input buffers
exceeds the number of input
buffers configured by mes-
sage command 2902.
Increase the number of input
buffers with message com-
mand 2902 or select a input
buffer, smaller than the maxi-
mum of input buffers config-
ured by message command
2902.
110C
Parameter error
Unit state = ST4 or ST5 and
one or more parameters are
not in range
Correct the parameters.
2201
Not executable in current
mode
Unit state = ST3
Nothing configured, please
perform message command
2902 before executing this
command.
