Connecting the AS interface bus
To set the address of the module on the AS interface bus, you need an addressing unit.
Valid addresses are in the range of 1 to 31. Use each address once only.
You can set the address on the AS interface bus before or after installation.
You can set the address on the AS interface bus before or after installation.
If the installed module is addressed via the address socket, the AS-Interface voltage must be
disconnected beforehand. This is necessary for safety reasons.

Networking on the AS interface bus
To make the connection to the AS interface bus, you need a communications-capable
LOGO! variant:
● LOGO! Base Module + CM AS-I.
To be able to send data across the AS interface bus to LOGO! and to receive data from it in
● LOGO! Base Module + CM AS-I.
To be able to send data across the AS interface bus to 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 or a DP/AS-I Link 20 E).
LOGO! can only be accepted as a slave on the AS interface bus. This means that it is not
● an AS interface power supply and
● an AS interface master (e.g. an S7-200 with a CP243-2 or a DP/AS-I Link 20 E).
LOGO! can only be accepted as a slave on the AS interface bus. This means that it is not
possible to directly exchange 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!
