Configuring the AS-i slave
Overview
Before data transfer can take place between the AS-i Master and the slave devices each
slave must be assigned an address. The address of a AS-i slave can be assigned using the
following methods:
● Addressing off-line using the Siemens Addressing Programmer
● Addressing on-line using the controlling system, such as a PLC via the AS-i Master (it
should be noted that only one slave with address 0 may be present on the bus if this
method is to be implemented).
The addresses are designated numbers between 1 and 31, with each slave device having a
preset address of 0. If the AS-i master detects a slave with address 0, it recognizes the
device and can automaticallly assign an address to the device and integrate the device into
the AS-i network (If more than one slave device has the address 0, the automatic address
assignment and integration is not possible).
Note
Profile 3.0
Under AS
-i Profile 3.0 it is possible to address 62 digital or 62 analog slave devices or a
combination of both digital and analog but not exceeding a total of 62 slave devices. This is
accomplis
hed by using the A/B address system. For example, two slaves can assigned as
number 1 slave device, by assigning them as 1A and 1B.
The addresses of the slave devices do not have to be sequential, for example the first slave
device can have the address 21, the next 10.
