Pressing the "mode" button for at least five seconds switches the gateway to con-
figuration mode. While in configuration mode, the yellow "prj mode" LED lights up.
The system then displays one after the other all detected slaves at a speed of two
per second. First all "A" slaves and afterwards all "B" slaves. If a "B" slave is dis-
played, the "AS-i active" LED blinks. If the display is empty, no slaves were deta-
ched on the AS-i circuit.
In configuration mode, all recognized slaves are activated except of slave zero.
The AS-i master is in normal operation. There is data exchange between the AS-i
master and all AS-i slaves detected by the master regardless of whether the de-
tected AS-i slaves were projected before.

Protected Operating Mode
6.3.1
Switching to Protected Operating Mode
The configuration mode can be left by pressing the "mode" button.
Pressing the button shortly:
Exits the configuration mode without projecting the current AS-i configuration.
Pressing the button for more than five seconds:
Exits the configuration mode and projects the actual AS-i configuration. Simul-
taneously the actual AS-i configuration is stored as nominal configuration in the
EEPROM.
In the protected operating mode, only AS-i slaves that are projected and whose
actual configurations match the nominal configurations will be activated.
6.3.2
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 projec-
ted 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.
Subject to reasonable modifications due to technical advances.

Operating the AS-i/CC-Link Gateway
When delivered the device is in configuration mode.
In contrast with the configuration mode in the protected mode there
is only data exchange between the AS-i master and the projected
AS-i slaves.
If the system detects an AS-i slave with address zero on the AS-i, it
can not leave the configuration mode.
