Transfer rate (1 Baud = 1 symbol per second)
The baud rate must be equal on the send and receive sides
0 = 300 Baud
1 = 600 Baud
2 = 1200 Baud (1.2k Baud)
3 = 2400 Baud (2.4k Baud)
4 = 4800 Baud (4.8k Baud)
5 = 9600 Baud (9.6k Baud)
6 = 19200 Baud (19.2k Baud)
7 = 38400 Baud (38.4k Baud)
8 = 57600 Baud (57.6k Baud)
Note
� With a fieldbus connection (option, for example, CANopen, PROFIBUS DP, and so on) modified ID numbers and different factory settings are stored here.
Detailed information is provided in the specific manuals of the relevant fieldbus interface card.
