12.1 System failures should be alerted according
to these performance standards.
12.2 Loss of system communication between the
CAM and connected systems should be indicated as a warning at the

should be removed from the list of active alerts on the CAM-HMI. After
reactivation of the communication all active alerts should be displayed
again.

system communication between the CAM and the connected systems should
not lead to the loss of the alert announcement functionality of the
individual functions.
