C.6
Operating as a profile device
Every manufactured PROFIBUS product has a unique PROFIBUS identification number which

which can identify a product as a generic profile device on the network.

Defining the device as Profile-specific as opposed to Manufacturer-specific makes it possible to
exchange the device for any other device of the same profile type without changing the GSD file.
To set up SITRANS LR250 as a profile device see PROFIBUS Ident Number (5.2.).
