Network Repeaters
Siemens provides network repeaters to connect PROFIBUS network segments.
See Figure B-5. The use of repeaters extends the overall network length, allows
you to add devices to a network, and/or provides a way to isolate different network
segments. PROFIBUS allows a maximum of 32 devices on a network segment of
up to 1,200 m (3,936 ft.) at 9600 baud. Each repeater allows you to add another 32
devices to the network and extend the network another 1,200 m (3,936 ft.) at
9600 baud. Up to 9 repeaters may be used in a network. Each repeater provides
bias and termination for the network segment. The order number for the RS–485
IP 20 Repeater, Isolated is 6ES7 972–0AA00–0XA0.
