Configuration
The dialogue shows the default CAN-bus settings. The ICM transmits all data
using a range of message identifiers starting at that selected. If the ``Use Defaults’’
button is pressed, the program constructs an identifier suitable for J1939
3
.
At the end of each test, the ICM will generate a ``test result codes’’ message using
the selected CAN-bus identifier.
On a J1939 network the test result will appear as PGN 0x00ff00. Users not using
J1939 can simply listen for messages with the identifier shown in the dialogue, e.g.
0x18FFB53F.
3.3 CAN 2.0A and CanOpen
The 11 bit format is designed to be compatible with the CanOpen standard. It
can also be used with any system that allows raw CAN-bus 2.0A identifiers to be
received.
In order to use 11 bit identifiers (CAN 2.0A) set a value below 0x7ff for the ``Base
Address’’.
For a CanOpen network, use a base address of 0x182 for example. This will result
in message IDs corresponding to the CanOpen ``pre-defined connection set’’.

i.e. This will use PGNs within the region allocated to proprietary applications, starting at 0x00FFB53F
