The FD-10 Profibus coupler from Westermo Data Communications is a
universal Profibus DP slave unit that is able to transfer data between
networks using serial links; no special drivers or PLC cards are
required. The coupler features RS232 and RS485 outputs and the same
serial protocol is used in both cases. It is supplied in three variants:
The FD-10P is a point-to-point link via direct cabling or leased telecoms
line, dial-up modem or wireless system and is capable of connecting two
widely separated Profibus DP networks. The FD-10A controls data transfer
between two or more independent Profibus networks on a single addressable
cable, multi-drop modem system or wireless network. This requires one
FD-10A to act as the serial master and two or more connected FD-10Ps to
control data exchange. For more advanced networking, the FD-10N can be
used in conjunction with multi-dropping modems or wireless network.
Network communication is controlled by Profibus masters within the
network, so additional system programming is required.
The FD-10 family is fully compatible with Profibus DP standard I/O data
and can facilitate simple and transparent data transfer of up to 65 DP
I/O words per cycle. It is configured using Westermo's Windows based
FD-Tool software.
