Configuration with T Connector and with Power Supply Connector

Definition
In a configuration with a power supply connector and a T connector, the DP/
ASi link is connected by means of a T connector to the PROFIBUS-DP.
The power supply is gated by means of the power supply connector with the
PROFIBUS-DP in a single cable.
Advantage
A slave station can be disconnected at any time from the bus without the "bus
traffic" being interrupted for the other slave stations.
The power supply is fed along the bus cable, i.e. an external power supply of
the slave station is not required.
Constraint The degree of expansion with a PS connector is limited (refer to section 3.4).
Cables You use cables of different design for the installation:
