Error handling

There are applications in which individual error events
are critical and must be permanently indicated, even if
the cause of the error has long been eliminated. In other
applications, it is desirable for the LED and the error
status to indicate the current state of CAN bus and
module, and for errors to automatically be deleted when
their cause is eliminated.
So in the MX Assistant, make a selection in the "CAN
bus settings" under "Error mode" to indicate how the
module should behave when transient errors occur:
If the "automatic, delayed" method is selected, the
error is automatically deleted from the error status after
the set delay time, and the state of the LED changes to
normal once the cause of the error has been eliminated.
Accordingly, the module shows the current state of the
CAN bus after the set delay.
If the "when reading" method is selected, the error sta­
tus remains, and is also indicated by the LED, until the
error status has been read out of the module. So pro­
vided the cause of the error no longer exists, the error
status and the state of the LED only change to normal
once the error status has been read out. This is also a
reliable way to detect individual error events without
having to constantly monitor the error status during mea­
surement. However, this method does not always reflect
the current state of the CAN bus.
