LOGO! installation and wiring

Networking on the AS interface bus

To make the connection to the AS interface bus, you need
a communications-capable LOGO! variant:
S
LOGO! basic module + CM AS-I.
To be able to send data across the AS interface bus to the
LOGO! and to receive data from it in the same way, you
also need
S
an AS interface power supply and
S
an AS interface master (e.g. an S7-200 with a
CP243-2).
LOGO! can only be accepted as a slave on the AS inter-
face bus. This means that it is not possible to directly ex-
change data between two LOGO! devices. Data is always
exchanged across the AS interface master.
