Hello,

thank you for the explanation. I initially used the busload frames (records) of the CANAPI 4, but it caused significant CPU load as we are utilizing all 6 interfaces of the PCAN-USB X6 at high bit rates. I observed processing of 6 x 2000 = 12000 busload records per second and did not want to ...

Hello,

we have a discrepancy in busload measurements: PCAN-USB X6 busload varies a lot between 40 and 80% while an external Trace Tool (non-PEAK) says steady 40% .

Bus ist 250 kBit/s
Messages are CAN 2.0 with extended identifiers
intervals between messages range from 0.5 to 5.5 milliseconds

Hello Marvin,

that's good news!

CAN_PARAM_TX_SELF_ACK is not defined in my version of CanApi4 (Header version 4.1.2 with CanApi4.dll version 4.2.0.128).

Is it possible to use this feature with this version somehow?
Do I need a new version of CanApi4?

Kind Regards
Martin Mödlinger

Hello,

thank you for your explanation. For the self-ack reason I am using the SINGLESHOT Feature of the CANAPI4.

But: When the REC increases during transmitting without cable, why does it not count down again when transmitting succeeds afterwards (after connecting a proper cable to a proper other ...

Hi,

I am sending CAN messages with CANAPI4 with CAN_MSGTYPE_SINGLESHOT. When there is no cable connected, I see an increasing RECEIVE (RX) Error Counter (REC), when there is a cable mit termination restistor but no other node ACKing, I see TRANSMIT (TX) Error Counter (TEC) increasing.

Why does the ...

Hello,

under high CAN load conditions the 4-channel PCAN-M.2 may cause Replay Timer Timeout and Replay Num Rollover errors on the PCIe root port it is connected to. The same is true when using a different M.2 slot. The same is not true for a PCAN-M.2 with only 2 channels. The PCIe root bridge ...

Hi,

does CAN_PARAM_AUTOBUSON also have an effect when the interface goes error-passive?

I am using CanApi4 Version 4.1.2 (with Driver Version 4.1.3.16213, HW is PCAN-USB X6 with FW 3.2.0)

Hi,

not hundreds, but dozens. And it HAS to be automatically (scriptable or programmatically). There is no display, keyboard or mouse on the target machines, neither the possiblity of Windows Desktop remote access.

I can achieve the file copying and "ejecting the media". I would just need to know ...

I have updated the Firmware of all 3 USB devices in the PCAN-USB X6 from 2.2.3 to 3.2.0.

Running the very same application now seems to work, even with setting the parameter CAN_PARAM_LISTEN_ONLY during operation.

Now I need to find a way of performing the Firmware Update programmatically out of ...

Driver Version for USB 3.0 is Intel version 2.0.0.102. This version schould be OK as mentioned in this forum.

I will do the Firmware Update and report the results.
