Compatibility GRV-CCANI-2

groov EPIC
1

Hi Everyone,
I’m starting a project where there is a Caterpillar engine. This engine has an engine control unit which communicates via SAE J1939 CAN. I would read the engine data on the epic using the GRV- CCANI-2 module. So my questions are:

  • Is it possible communicate between the epic and the engine via CAN?
  • Do I need write a particular code?
  • Can I connect the engine CAN wires directly to the module?

Thank you so much for the support.

The GRV-CCANI-2 only works with Codesys and I don’t have a lot of experience with that.
Lets page @greichert and get his input… I know hes helped some other customers with that module.

Can the module transmit? I have always wondered about the ‘safety’ of writing to ECUs…

Any chance you could repost the sample project again for using the can module in Codesys? I basically have the same situation and would like to try using our new Groov Board. The dropbox link has been deleted.

Thanks.

Hi JMatheny, I don’t have a copy of the example project that GReichert posted but this video should help you get started https://www.youtube.com/watch?v=NU0rKgShTpM&t=227s along with the Codesys documentation https://content.helpme-codesys.com/en/CODESYS%20CANbus/\_can_f_j1939.html
