Figure 7-23
To avoid wiring errors, unique coding patterns must be defined for the connectors X520,
X521 and X522.
Possible patterns:
● 3 connectors on one component are encoded differently (i.e. X520, X521 and X522).
● Different component types are encoded differently.
● Otherwise identical components are encoded differently on the same machine,
(e.g. several TM15-type components).
