Functions
Configuration in Run (CiR), requires host application program support
Timestamp (Master functionality)
Redundancy
Supported, requires host application program support
Baud rate
9,6 kBits/s,
19,2 kBits/s,
31,25 kBits/s,
45,45 kBits/s
93,75 kBits/s,
187,5 kBits/s,
500 kBits/s,
1, 5 MBits/s,
3 MBits/s,
6 MBits/s,
12 MBit/s
Auto baud rate detection is not supported
Data transport layer
PROFIBUS FDL
Limitations
DPV2 isochronous mode and slave slave communication are not
supported.
The redundancy function cannot be used, if the master is configured by
the host application program by packets.
