Setup and Configuration of the AS-i Network
Before you actually program your automation solution, you must set up your system and connect and
parameterize the AS-i components involved.
The yellow AS-i shaped cable enables fast and easy installation of your slaves in the AS-i network. This
cable is the transmission medium for communication between the master and the stations. It also carries
the supply voltage for the stations. A slave is identified by its address, which is always stored in non-
volatile memory in the slave.
On delivery, all slaves have the address “zero” by default. Each slave in the network must have a unique
address that is not “zero”.
The C7-621-AS-i allows you to change the set address of a slave through operation on the C7. When
using the C7 addressing function, it is therefore necessary to connect all new slaves to the AS-i cable
consecutively to ensure that they are each assigned a unique address.
Set up your AS-i network according to the diagram above. Connect your slave 1 to your yellow AS-i
shaped cable. If you have problems connecting the slaves to the AS-i cable, please read the setup
instructions supplied with the AS-i components.
