ETHCAN_ERR_ILLHANDLE

An invalid instance handle was passed to the function. One possible

cause for this error is the return of an instance handle with an invalid

instance number, 0 for example. In addition the driver only supports

max. 5 instances so that the return of an instance handle greater than 5

will also result in this error.

ETHCAN_ERR_HWNOINIT

The function was called with an instance handle, for which the

corresponding hardware initialization function was not yet called.

Therefore the function EthCanInitHardware() has to be called, which

will return a valid instance handle upon successful completion.

ETHCAN_ERR_HWINUSE

The function EthCanInitHardware() was called with an instance

handle, for which the initialization routine was already called and

returned successfully. In order to perform a new initialization with

modified parameter values, the de-initialization function

EthCanDeinitHardware() has to be called before a new initialization

can occur.

ETHCAN_ERR_HWNOTCONNECTED

The function was called, but at the time of the call there was no

connection of the CAN-Ethernet Gateway to the PC. A possible cause

may be a break in the connection as a result of the loss of the physical

link (Ethernet cable was disconnected).

If a callback function was assigned during initialization, the

application is able to react to this event. For example, the send and

receive functions for a CAN message should only be polled if the

connection status is kEstablished.

If no callback function is defined then the function

EthCanGetConnectionState() should be used to poll the connection

status. Following a successful ”Reconnect“ the function can be called

again.
