4.1.21. Device ID Switch Changed Alert (No Display Code)
This condition is reported when the device EtherCAT address rotary switches
have been changed and do not represent the address last reported to the
Master. Note: If the master is using station alias address register to access
the device address (known as legacy addressing), then the device cannot
detect when the master has read the switch setting and this condition will be
reported until the MFC has power cycled or otherwise reset.
