At power–up, the "DP slave POSMO A" automatically detects the baud
rate set on the fieldbus.
When commissioning the fieldbus, the baud rate is defined the same
for all devices starting from the master.
Data is transferred between the master and slaves according to the
master/slave principle. The drives are always the slaves.
This permits extremely fast cyclic data transfer.
For SIMODRIVE POSMO A for communications via PROFIBUS, the
following properties are involved:
The PROFIBUS node address and the terminating resistor are perma-
nently set in the connection cover of SIMODRIVE POSMO A.
