2. Hardware Implementation of the LUFP7 Gateway

To connect stations to the Profibus-DP network more easily, several accessories are offered in the Schneider Electric catalogue:

Single twisted pair type A Profibus-DP cable (100 m long): TSX PB SCA100. If you use a different cable, please check that its electric characteristics are as close as possible to those of type A cables (see chapter 7.2 Communication Characteristics, page 86).

Line connector: 490 NAD 911 04. The SUD-D 9-point male plug on that connector should not be connected to a station located at the segment end, as the connector has no line termination. This passive box contains a printed circuit fitted with one or two terminal boxes with screws for connecting one incoming Profibus- DP cable and one outgoing Profibus-DP cable.

End of line connector: 490 NAD 911 03. The SUB-D 9-point male plug on that connector must be imperatively connected to a station located at segment end, since the connector has a line termination. This passive box contains a printed circuit fitted with one terminal box with screws for connecting one incoming Profibus-DP cable.
