The fieldbus coupler serves to integrate I/O modules of series 767 into a
PROFINET network. Based on IP class C, PROFINET IO structurally allows the
connection of up to 253 fieldbus couplers with 63 I/O modules each.
IP network
In an IP network, the addresses 0 and 255 are reserved. At least one other IP
address is reserved for the IO Controller.
The maximum number of fieldbus couplers is dependent on the utilized IO
Controller and the available user data of the connected I/O modules.
Every topology can be implemented in a PROFINET network. The two
ETHERNET connections of the fieldbus coupler are internally connected via an
ETHERNET switch. Therefore, you can integrate the fieldbus coupler not only in
a network with star topology, but also with line topology. The maximum distance
between two fieldbus couplers is 100 m. Up to 20 fieldbus couplers are
cascadable, such that a maximum line of 2 km can be achieved.
In order to set up a connection with an IO Controller, the fieldbus coupler must be
connected to a network with a transfer rate of 100 Mbit/s in full-duplex mode. A
different network setup is not allowed according to PROFINET specifications for
cyclic data exchange. For this reason, only switches are to be used in a
PROFINET network.
An internal server is available to you for Web-based applications. In essence,
HTML pages stored in the fieldbus coupler allow access to information on time
settings and status of the fieldbus node via Web browsers.
