Hello Abdallah

it all depends what the "automat" is expecting. It could be using some CAN frames specified by manufacturer of this "automat" and it could be that it is some standardized protocol. Tn this case I assume it is CANopen[1] and you have to implement his protocol using a commercial available protocol stack. CiA [2] has a listing.

My first advice: talk with the manufacturer of the machine you like to connect with. Ask him. Ask which protocol you have to implement.
