cyclic operation, then alarm A50005 "Sender was not found on the SINAMICS Link" is output
to the other nodes.
The alarm value contains the number of the sender that cannot be located The alarm is
automatically canceled after the fault has been resolved at the node involved.
If several nodes are involved, the message occurs a multiple number of times consecutively
with different node numbers. The alarm is automatically canceled after the fault has been
resolved at the nodes involved.
When a node fails in cyclic operation, in addition to alarm A50005, fault F08501 "COMM
