Relay cross references are used to track signals, which need to be tracked for components with outgoing
contacts. A contact overview with information about the contact types of a relay and their positions in the
circuit diagram is additionally attached to the bottom of each relay coil.
Example: (K61/9.6)
indicates that
the relay coil on page 9 is found in current path 6.

Potential cross references serve the purpose of tracking signals, which are transmitted from one func-
tional diagram to another. Potential cross-references may additionally have structural symbols assigned
to them.
Example: → S15:11/=OPT/41.0
is continued to the right to page 41, current path 0.
OPT
stands
for option.

Current paths are numbered successively from 0 to 9.
The list of components is the first evaluation list that follows the
functional diagrams. This list contains all components used in the
circuit diagram, except terminal strips and plugs.
