Notes and explanations Special care must be taken to place the cable into the carriages for the lowerparts to ensure a good contact. The carriages have the same colour code as
the flat cable (yellow = AS-i, black = 24 V DC).

After all slaves are correctly connected and addressed, the last step is carriedout. The master must be informed which slaves must be present for a system
to operate (list of the projected slaves LPS). This is done by the automatic
configuration (for the plc master for example by pressing a button, for ifm
controllers conveniently via the menu). In this process the AS-i master briefly
passes to the projection mode, reads the current projection of all connected
slaves and saves it permanently.

extension Caution: The AS-i minus or plus poles must not be con-nected to ground at any point. Only the shield / GND
connection at the AS-i power supply must be ground-
ed! Input and output potentials have reference to the
related AS-i module. Mixing reference potentials over
several modules is not allowed. In the control cabinet the yellow AS-i cable should be laid uninterrupted tothe AS-i power supply. The master is connected in parallel (blue = AS-i–,
brown = AS-i+). If further input / output modules are to be used in the con-
trol cabinet, separate wiring (spurs) is recommended, starting from the AS-i
power supply.
