Communication failure when booting or in cyclic operation

If at least one sender does not correctly boot after commissioning or fails in cyclic operation,
then alarm A50005 is output to the other nodes: "Sender was not found on the SINAMICS
Link."
The message contains the number of the faulted node. After you have resolved the fault at
the node involved and the system has identified the node, the system automatically
withdraws the alarm.
If several nodes are involved, the message occurs a multiple number of times consecutively
with different node numbers. After you have resolved all of the faults, the system
automatically withdraws the alarm.
When a node fails in cyclic operation, in addition to alarm A50005, fault F08501 is output:
"COMM BOARD: Monitoring time, process data expired"
