View Full Version : CR0403 and J1939

01-24-2012, 04:52 PM
In the manual for the CR0403 it lists:

1 CAN interface (internal)
- RAW-CAN protocol
- for I/O extension and display
1 CAN interface supports the protocols...
- SAE J1939
- CANopen master
- CANopen slave

Which (CAN1/CAN2) interface is this referring to? Am I able to use J1939 on either? Can I use J1939 (with a Grayhill keypad) on the same channel as CANOPEN (CR0451)? Also, are the J1939_x_Vxxxxxx libraries supported on the Basic series?

You have to use the J1939_NT library for the CR04xx controllers, also for the CR108x displays.

They call out the channels in the function blocks so its available on either can port. I haven't tried to mix and match CANopen and J1939 on the CR0451, I advice against it because there are some other third party components that don't work well if there are 11 bit identifiers on the bus.

You can do Network Variables and J1939 at the same time.
