Display of Slave Status

About us
At a Glance
Slave devices connected to the bus are displayed in the AS-i Configuration after clicking on the AS-i Bus Diag. button. On each side of the slave number, two different icons are displayed, indicating whether the slave was specified and if it was detected.
NOTE: Input image words send back information on the state of the AS-i bus, and not on the inputs. As the PLC is in RUN, the application will have to acknowledge this change in mode, in order not to interpret the state of the AS-i bus instead of the inputs. Bit %I\2.e\0.0.0.1 (where e is the connection point number for the module on the Fipio bus) indicates this mode.
Displaying Slave Status
For each slave device, one of the following four scenarios can occur:
Scenario

Explanation
1

The slave P specified in configuration and the detected slave D are identical.
2

The slave P specified in configuration and the detected slave D are not identical. The slave is declared faulty (1).
3

A slave P is specified at configuration but no slave is detected. The slave is declared faulty (1).
4

An additional slave, not specified at configuration, is connected to the bus. The slave is declared faulty (1).
Key:

When a slave is faulty, the icons situated beside the number, as well as the AS-i Bus Diag. button and Fault tab turn red.
Note: The Profile field in the Slave area of the debug screen allows you to check if the profiles of the specified (Projected) slave and the Detected slave are really identical.
