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.

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 module + CM AS-I.
To be able to send data across the AS interface bus to IDEC

SmartRelay and to receive data from it in the same way, you

also need:
• 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

exchange data between two IDEC SmartRelay devices.

Data is always exchanged across the AS interface master.
