Hello,

I'm facing a mysterious problem with the CANbus API 1.0.0.3.

After sending 64 messages, the CANbus hang :

CECC_S.Application.CAN_TEST.Diag.ctSendCounter : 64
CECC_S.Application.CAN_TEST.Diag.ctReceiveCounter : 0
CECC_S.Application.CAN_TEST.Diag.ctRxErrorCounter : 0
CECC_S.Application.CAN_TEST.Diag.ctTxErrorCounter : 1
CECC_S.Application.CAN_TEST.Diag.ctLostCounter : 0
CECC_S.Application.CAN_TEST.Diag.ctReceivePoolSize : 100
CECC_S.Application.CAN_TEST.Diag.ctReceiveQueueLength : 0
CECC_S.Application.CAN_TEST.Diag.ctTransmitPoolSize : 9
CECC_S.Application.CAN_TEST.Diag.ctTransmitQueueLength : 1
CECC_S.Application.CAN_TEST.Diag.xBusAlarm : FALSE
CECC_S.Application.CAN_TEST.Diag.usiBusLoad : 0
CECC_S.Application.CAN_TEST.Diag.xSendingActive : TRUE
CECC_S.Application.CAN_TEST.Diag.eState : PASSIVE
CECC_S.Application.CAN_TEST.Diag.uiBaudrate : 500

I need some help please.

Thank you very much.

Hello,

Can you solved the problem? The same happening here.

Hi,

i have the same issue, with a rasppery pi.

The codesys version i use is the 3.5 SP18 and raspberpy pi runtime with 4.4.0.0. I builed a new kernel for the raspberry pi with enabled realtime patch.

Does anybody now get around this issue?

As in the system 2 CANs are used one with the canopen manager which is working fine. Only the can with the CAN API Library is having this issue.

thanks Micky
