Additional Notes On Configuration - Siemens Simatic PCS 7 Commissioning Manual

Checking the bus parameters
HW Config checks whether the bus parameters have to be changed when you add a new FF
device. If changes are required, the message "Change bus parameters" will be displayed. You
can then decide if you want to change the bus parameters.
● Changing bus parameters: No
● Changing bus parameters: Yes
You can find additional information on this in the following sections:
● Section "Bus parameters (Page 34)"
● Section "How to set the bus parameters (Page 39)"
