Figure 7-1
The illustrated Inline station is a typical example. It shows the supply and provision of
different voltages and their forwarding via potential jumpers. Explanations for this can be
found in the following sections.
S1.1
Main circuit (e.g., M1, M2)
Segment circuit y in main circuit x (e.g., S2.1, S2.2)
Bus coupler in conjunction with a power terminal, if required
Bus coupler supply (supply for bus coupler, generates U
Main supply (I/O supply in the main circuit)
Segment supply (I/O supply in the segment circuit)
I/O supply for analog terminals
Communications power
Data jumper for the local bus
Ground (GND for the supply voltages U
