Nominal token rotation time: Projected
time interval for a master to receive a
token; results from the total of token
waiting times for all masters on the bus.

circuits after which a search is
performed for an additional, newly
added, active station in the master GAP
(address range of own bus address up to
address of next active subscriber)
Maximum number of repeated callup
attempts by master, when it has not
received a valid reply from the slave.
Time between two bus cycles, during
which a slave can process a request
from the master (time base 100 µs); the

Maximum time for requester (DP master
class 2) to pick up a reply from the
master during master-master
communication (time base 1 ms).
