SIPROTEC PROFIBUS-DP - Communication profile
C53000-L1840-B001-03
32
For exclusive utilization of PSE modules at the bus.
This value could be smaller depending on the used PROFIBUS-DP master and further
modules at the bus.
If more than 32 devices are needed, RS485 repeaters (e.g. 6ES7 972-0AA00-0XA0)
have to be used.
