FD-10 Profibus couplers are universal Profibus DP slave units that are able to transfer Profibus DP process data between networks using serial links without the use of special drivers or PLC cards.
FD-10 Profibus couplers from Westermo Data Communications are universal Profibus DP slave units that are able to transfer Profibus DP process data between networks using serial links without the use of special drivers or PLC cards.
The FD-10 has RS232 and RS485 outputs, and the same serial protocol is used in both cases.
Three variants exist: with the FD-10P, provides a point-to-point link via direct cabling, or it can be used with a leased line, dialup modem or radio system to connect two widely separated Profibus DP networks.
The FD-10A can be used to control data transfer between two or more other independent Profibus networks on a single addressable cable, multidrop modem system or a radio network.
This method requires one FD-10A to act as the serial master and two or more connected FD-10P's to control data exchange within the remote networks.
For more advanced networking requirements the FD-10N can be used in conjunction with multidropping modems or a radio network.
Network communication is controlled by Profibus masters within the network and hence more system programming is required.
The FD-10 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 easily configured with FD-Tool, a Windows-based software tool.
