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 ad-
dress once only.
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 IDEC SmartRelay variant:
• IDEC SmartRelay base FL1B-CAS2.
• an AS interface power supply and
• an AS interface master.
IDEC SmartRelay can only be accepted as a slave on the AS
interface bus. This means that it is not possible to directly ex-
change data between two IDEC SmartRelay devices. Data
is always exchanged across the AS interface master.
