2.1.1
Configuration with Power Supply Connector without T Connector
In a configuration with looped field bus and power supply, the individual
modules are connected directly to the field bus.
The power supply is combined with the field bus in a single cable via the
power supply connector.
You do not need a T connector.
The power supply is run over the bus cable, i.e. no external power supply is
required for the slave station.
If a slave station is disconnected from the bus, the “Bus traffic” is interrupted
for slave stations located further down the line.
Since there is then no terminating resistor available, bus traffic might be dis-
turbed for slave stations still connected to the bus.
The level of expansion using one power supply connector is limited
(see Section 2.1.3).
Different types of cable can be used for the various configurations:
Read Section 3.11 if you wish to use prefabricated cables from Siemens.
Read Section 4.3 if you wish to prepare the cables yourself.
