Line Change
The LION system can be subdivided in three galvanic insulated sections (lines).
For the galvanic insulation, a SIL0 line coupler must be installed at the end of the
line and at the beginning of the following line.
The SIL0 line couplers are transparent and not visible as a SIL2 bus subscriber.
The SIL0 line couplers have no address and do not communicate.

Energy Supply Range
A SIL2 power supply supplies all components that are on the right. The system
can be subdivided in different sections. If the maximum energy requirement of the
modules exceeds the nominal value of the power supply, the sections need to be
supplied by an additional SIL2 power supply.
The SIL2 power supplies are transparent and not visible as a SIL2 bus subscriber.
The SIL2 power supplies have no address and do not communicate.
