Networking on the AS interface bus
To make the connection to the AS interface bus, you need
a communications-capable LOGO! variant:
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
an AS interface power supply and
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.
!
Warning
The AS-Interface and LOGO! systems must
never be connected together electrically!
Use safe isolation acc. to IEC 61131–2, EN
50178, UL 508, CSA C22.2 No. 142.
