Note 1 On response code 0000, the unit configures the output message buffer identified with buffer
number with the following properties:
• Extended identifier length (11-bit)
• Identifier number
• Send mode, (see Sending CAN Messages in Section 1)
• Send cycle time (if the send mode is 2)
• Big or little endian format, see Send Buffer Area on page 8

Configure 29-Bit ID Output Message Buffer (2904)

Each Output (Send) Buffer requires the following settings that are configured using the command code
2904.
• the 29-bit identifier
• the method of sending (SM1 = triggered, SM2 = on change or SM3 = cyclic)
• the send cycle
• the use of little endian or big endian

Correction
Number of output buffers
exceeds the number of out-
put buffers configured by
message command 2902.
Increase the number of output
buffers with message com-
mand 2902 or select an out-
put buffer smaller than de
maximum of output buffers
configured by message com-
mand 2902.
Set the send cycle different
from zero or change the send
mode.
Correct the parameters.
Nothing configured. Perform
message command 2902
before executing this com-
mand
Disable communications,
reconfigure the buffer and
enable communications.
