6.4.2 Configuration Errors in Protected Operating Mode
As long as there is no configuration error, the numeric display is turned off while in
protected operating mode. Otherwise, the address with a faulty assignment is dis-
played. A faulty assignment occurs when a slave has been recognized or projected
but cannot be activated.
If there are more than one faulty assignments the one that was first detected is dis-
played. Pressing the “set” button shortly displays the next higher faulty address.
Shortly appearing configuration errors are stored in the device (advanced AS-i diag-
nosis). The last error that occurred can be displayed by pressing the set button. If a
short AS-i power failure is responsible for the configuration error the display shows a
“39”.
6.5 Assigning an AS-i Address in Configuration Mode
AS-i can be put into operation in a very comfortable manner by using the Windows
software AS-i Control Tools (see chapter 9.1)(addressing directly or with the AS-i ad-
dress assistant).
Furthermore you can use a hand held addressing device.
If you don’t have neither a PC nor a hand held addressing device, address assigning
of the AS-i slaves is also possible with the AS-i gateway using the push buttons. How
it works is described as follows.
6.5.1 Assigning a Slave Address
(assigning an available address to a slave with address zero)
In configuration mode, the addresses of all detected slaves are displayed one after
the other. To display the next higher available operating address, press the “set” but-
ton shortly. Each time you press the “set” button, the next available address is dis-
played.
Choose the displayed address as your target address by pressing the button for more
than five seconds. The address display blinks. The master is ready for programming;
pressing the “set” button again addresses the connected slave with address zero to
the target (blinking address).
Any errors will be displayed by their error codes according to chapter 9. Otherwise,
the detected slaves are displayed again as described in chapter 6.3.
6.5.2 Erasing the Slave Address
(assigning address zero to a detected slave)
In configuration mode, the addresses of all recognized slaves are displayed one after
the other. By pressing and releasing the “set” button, the master displays the next
available address. If you press the button for more than five seconds while the ad-
dress of a detected slave is displayed, this slave will get the address zero and the dis-
play shows “00”.
When you release the button, the display continues to display the detected slaves.
