6.2.3.6 Module resources

It is true to say that totaled across all CAN connections,
the MX471B can decode up to 100,000 signals per
second and create CAN messages for sending. If this
value is exceeded, CAN message decoding and creation
is interrupted until once again, less signals are received
or being created. This ensures that the module remains
accessible even in an overload situation. A relevant error
code is entered in the module error status, and all status
LEDs glow constantly red.

State indication by LED

A distinction is made between the general kind of error
message (see Chapter 5.2.1), such as an incorrect bit
rate setting, and errors that are dependent on the receive
or transmit parameterization. If no transmit channel is
parameterized, errors in the sending direction will be
ignored. Conversely, there is no error signaling from CAN
receiving, if no CAN signals are parameterized in the
receive direction.
If the connection LED does not glow green in normal
mode, there are usually error messages present, which
can be read out via the error status.

MX840B

The behavior of the channel LED in CAN operating mode
is described for the MX840B. The flickering of the LED
during activity on the CAN bus is not synchronized with
the individual messages.
