Figure 88 CAN configuration window
CAN message ID type : Message ID type (Figure 89) two types according to SAEJ1939
standard: Standard ID (value: 0 to 0x7FFh) and Extended ID (value: 0 to 0x1FFFFFFFh).
Figure 89 CAN message ID types
Message ID value is entered in hex format. This parameter is used to configure hardware
message filter (Figure 90). All messages contain 8 bytes of data, to select particular data/bytes
“Output Data Mask” is used, it’s done by ticking required bytes, only selected bytes are sent to
server.

16.3 Example
A sample CAN message has the following structure: X18FEE9018FFFFFFFF23840300, where
essential parts are ‘FEE9’ – identifier and ‘FFFFFFFF23840300’ – data bytes.
CAN messages are configured like any other I/O parameters. They consist of 4 identifier
bytes and 8 data bytes. Below you will find a sample configuration for fuel consumption
parameter:
ID type – is always 29 bits.
Output data mask – defines which data bytes are sent to the server (sometimes not all data
bytes are necessary).
