Handheld device provides CAN bus diagnostics
The PCAN-Diag from Peak-System is a handheld device for the diagnostics of a CAN bus network on OSI layers 1 and 2. With firmware 1.7, the device obtains features like the busload diagram displaying an additional graph for busload that is generated by error frames. This is done in a split view parallel to the busload by regular CAN frames.
If the oscilloscope function identifies the sampled signal course as a CAN frame, the new report function shows detailed characteristics of that frame. This allows the user to determine conclusions about the structure of the CAN network.
Two display modes are available for multiplexer variables. Either all variables of a multiplexer are shown together, or they are displayed separately for each multiplexer state.
The PCAN-Diag can display the data traffic from a connected CAN bus in a basic manner in hexadecimal format as well as in symbolic form. There’s a trace function to record the data stream for later review. At faulty communication, the diagnostics can be refined with busload measurements or, on hardware layer, with termination and voltage measurements.
