TCP Receive Number of via TCP/UDP received CAN messages (CAN

firmware)

TCP Transmit Number of via TCP/UDP transmitted CAN messages (CAN

firmware)

CAN Receive Number of received CAN messages (CAN bus, CAN driver)

CAN Transmit Number of transmitted CAN messages (CAN bus, CAN driver)

CAN Discard • Timeout sending CAN telegram (1s)

This indicates that no active partner is connected to the

CAN bus (no ACK received). Also a wrong baud rate or

missing termination can cause this error.

• A CAN telegram received from CAN bus is discared because

the receive buffer is full (600 entries)

This happens when the CAN firmware does not read

telgrams fast enough out of the driver receive buffer. This

may be the case even if CAN telegrams routed via TCP/UPD

can not received fast enough by the connected ethernet

client(PC,PLC) because of load problems (e.g. full receive

TCP buffers).
