CAN identifiers
In the shipped state, following start-up of the IO-Box32-CAN, the identifiers
are set according to the specifications of the CIA DS-301 (master/slave con-
nection set):
D the B∼IO67-CAN system acts completely as a slave.
An application master, DBT master or NMT master can use the node ID of
the slave to calculate its identifier.
D no communication between slaves.
Via SDO, a DBT master can change the identifiers of the IO-BOX32-CAN in
any way so that direct communication of process data is possible among
slaves.
Standard identifier assignment (ID length 11 bits = range of 0 to 2047) ac-
cording to specifications of the 'predef. Master/Slave Connection Set'.
