FAQs About Fieldbuses

Why do we need a Profibus DP master in both ends of a point to point communication with FD-10?
The FD-10 is just transferring the I/O information and not the profibus frame. The I/O information will be inserted in a profibus DP frame on the remote side. The FD-10 is a profibus slave and need a profibus master to control the communication in the profibus network.
