By using a Virtual CAN Bus, we separate the control task from other tasks. The distributed embedded control system can be developed using standard CAN Controllers and transceivers in a traditional way with well proven tools.
Other tasks such as encryption, transmitter authentication, re-flashing, etc. can be developed by experts in these fields and carried out by using other protocols. With modern technology, the different tasks can run in parallel and simultaneously communicate on the same physical layer.
It is a great advantage to separate the control problems from other problems. The control problem can be solved once and for all by the control experts and other problems by experts in their respective technology fields.
The Kvaser Mini PCI Express HS is a highly-integrated CAN (controller area network) add-on board that lets embedded system developers add CAN functionality to any standard computer board with mini PCI Express capability.
The add on board offers a single channel, high speed CAN interface with error frame detection and on-board buffer. This board has a low profile connector that complies with the mini PCI Express standard, which connects via a cable to a DSUB connector (or other type) at the computer housing. With just the CAN communication link itself exposed, total system EMC performance is protected because all the electronics remain inside the computer housing.
