QUESTION:
Which PROFIBUS DP baud rates can I use for the communication to my
ET200S FO module?
ANSWER:
The module supports the following baud rates:
- 12 Mbit/s
- 1.5 Mbit/s
- 500 Kbit/s
- 187 Kbit/s
- 93.7 Kbit/s
- 19.2 Kbit/s
- 9.6 Kbit/s
If you try to set a different baud rate, then in STEP 7
V5.2 you get the error message shown in Fig. 1.

Important:
In STEP 7 V5.1 it is also possible to set transmission rates
of 3 Mbit/s and 6 Mbit/s. But these baud rates are not suitable for
secure communications.
