Fieldbus Connection
The connection to the fieldbus is made via two RJ-45 plugs (also called
"Western plugs").
Each port supports the transmission speeds 10/100 Mbit as well as the
transmission modes full and half-duplex.
The wiring of these plugs corresponds to the specifications
for 100BaseTX, which prescribes a category 5 twisted pair cable as the
connecting cable. Cable types S-UTP (Screened Unshielded Twisted Pair) and
STP (Shielded Twisted Pair) with a maximum segment length of 100 m
(approximately 328.08 feet) can be used.
The socket is arranged physically lower, allowing the coupler to fit in an 80 mm
high enclosure after plug connection.
