Setting the AS-i address 

Unique addressing    

In the factory setting, an I/O module (slave) has the address 0. It is detected by the master 

as a new slave that has not yet been addressed and, in this condition, has not yet been 

integrated in standard communication/data exchange. 
To enable data to be exchanged between the master and slaves, you have to assign a 

unique address for each slave (i.e. each slave address must be different) when 

commissioning the AS-Interface network. 
You can select any address in the address space from 1A to 31A and 1B to 31B. 

Thus a maximum of 62 nodes are possible in one AS-Interface network. 

Addressing the slaves 

You can set the slave address in different ways: 
●  Offline with the addressing unit at the AS-i connection. 

Recommended if you want to assign addresses for the entire system. The direct 

connection between the slave (motor starter) and addressing unit ensures that the slaves 

are not mixed up. 

●  Online by the AS-i master or in the PLC configuration software.  

Recommended if you want to assign addresses to individual slaves if an addressing unit 

is not available.  

Before assigning addresses, you must ensure that each address exists only once in the 

AS-i network, that is, several new, additional modules (with address 0 in as-delivered 

condition) must not be connected to the AS-i cable. 

 

CAUTION 

 

As soon as you have assigned a valid address outputs can be set or inputs read that result 

in follow-up switching operations. To prevent a hazardous condition switch off the voltage
