AS-i Bus Displayed in the Project Browser

At a Glance

When you declare a TSX SAY 100 module on the PLC rack, the AS-i bus is represented in the configuration directory of the project browser. The number of the AS-i bus is calculated automatically by Control Expert. This value may be modified.

After having declared all the slaves on the AS-i bus and validated the configuration, the AS-i slaves also appear on the AS-i bus of the project browser. Each slave appears with its address number. Displaying the AS-i bus and slaves enables you to know at a glance their topological addressing.

The following illustration shows the AS-i bus and slaves in the project browser;

In the project browser, the AS-i bus is represented by AS-i V1 and the AS-i V2 is represented by AS-i V2.

Modifying the Bus Number

It is possible to modify the AS-I bus number by following the below instructions:

Step	Action
1	Close the AS-I module configuration screen (if it is open).
2	In the project browser, right click on the AS-I module and select properties.
3	In the Bus properties window, select the desired bus number (between 1 and 999).
4	Click on OK to confirm the modification. Result: the addresses of the slave devices directly associated with the AS-I bus module are automatically modified.

NOTE: You are advised not to use the number 2 bus for the AS-I bus because this number is reserved for the Fipio bus.
