Connection of the Fieldbus Box modules
The Fieldbus Box modules are connected either directly or via a T-piece (or Y-piece).
The B318 series features a socket and a plug connector, i.e. this is where the PROFIBUS is routed in the
module. The supply voltage (+5 V
DC
) for the termination resistor is only present at the socket. The termination
resistor ZS1000-1610 is only available as a plug connector.
The incoming PROFIBUS line should always end with a socket.

Two T-pieces are available:
• ZS1031-2600 with +5 V
DC
transfer for supplying the termination resistor
• ZS1031-2610 w5 V
DC
transfer

PROFIBUS cabling
Physical aspects of the data transmission are defined in the PROFIBUS standard (see PROFIBUS layer 1:
Physical Layer).
The types of area where a fieldbus system can be used is largely determined by the choice of the
transmission medium and the physical bus interface. In addition to the requirements for transmission
security, the expense and work involved in acquiring and installing the bus cable is of crucial significance.
The PROFIBUS standard therefore allows for a variety of implementations of the transmission technology
while retaining a uniform bus protocol.
Cable-based transmission
This version, which accords with the American EIA RS-485 standard, was specified as a basic version for
applications in production engineering, building management and drive technology. A twisted copper cable
with one pair of conductors is used. Depending on the intended application area (EMC aspects should be
considered) the screening may be omitted.
Two types of conductor are available, with differing maximum conductor lengths (see the RS-485 table).
