CAN FD Interface, STE 6/100/200

Modern CAN FD data bus node for generating CAN FD messages and for converting classic CAN 2.0 and CAN FD messages.

Generation of CAN FD messages

The module generates CAN FD messages as they are used in the most modern vehicles, which can be examined in a practical manner with a digital storage oscilloscope (DSO). In contrast to the original control units, it is programmed in such a way that it can be operated together with the DSO without switching to error mode - without a second control unit on the bus.
The bit rate switching (BRS) during the actual data transmission can be switched on and off during operation in order to better recognize the effect in the oscillogram.
In connection with a CAN data analyzer, the contents of the messages can be displayed and evaluated in tabular form or continuously. This is particularly interesting for the further tasks for:

Conversion of CAN messages

Received CAN 2.0 messages can be converted into CAN FD messages and vice versa. In this way, combining several classic messages into a "high-speed" message can be examined in a didactic manner and with an additional plug-in element a CAN FD transmission line can be set up.
