ID CAN Message (290

Note 1
On response code 0000, the unit sends a message with an extended identifier length with the
provided identifier, data length and data depending on the provided endian flag.
Additional Information
•
On all response codes different from 0000, the unit will not transmit the user defined CAN
message.
•
All of the 8 data bytes are always part of the command message. The actual data length of the
CAN message (data length in bytes) can be less than 08. The length of the command must
always equal 8 words.
The instruction is used to transmit a user defined CAN message. The User Defined CAN Unit will not
check the validity of the CAN message.
The following table defines the minimum and maximum values for each item in the command block with
setting details.
