6.2 The AS-i network
The AS-i network can be wired according to a tree configuration, a linear configuration with sections or a star
configuration. These three architectures can be used simultaneously.
6.2.1 AS-i power supplies
An AS-i power supply is specific to the AS-i network.
• Output voltage between 31.6 VDC and 29.5 VDC
• Output current:
− 4A for 31 installed slaves
− 8A for 62 installed slaves
I = (No. of AS-i modules x 0.092) + gateway intensity
6.2.2 AS-i address programming
The AS-i address for the module is programmed either via the AS-i master (PLC coupling, gateway, etc.) or
via the addressing terminal (7008215).
The M12 connector can be used to disconnect the module from the AS-i network and to program the network
address via the 7008215 addressing terminal.
Notes:
▪ The module is programmed to address 0 by default.
▪ Do not program two modules with the same network address.
▪ The AS-i 2.0 modules have an address between 1 and 31.
▪ The AS-i 3.0 and AS-i 2.1 modules have an address between 1A and 31A and 1B and
31B.
