5 Operating the AS-i/INTERBUS Gateway
5.1 Master Start-Up
After powering on, all segments of the figure display and all LEDs light up for ap-
proximately one second (self-test). Afterwards, the LEDs display the condition of
their respective flags. The figure display shows the condition of the master:
OFPOff-line Phase
The AS-i master initializes - there is no data communication on the AS-i.
SEA Detection Phase (search)
Start of the start-up phase, where the system looks for slaves located on
the AS-i. The master remains in the detection phase until it finds at least
one slave.

1
Activation Phase
Condition at the end of the start-up operation where the parameters are
transmitted to all connected and recognized slaves. This enables access
to the AS-i slaves’ data connections.

Start of Normal Operation
In normal operation the AS-i master can exchange data with all active
slaves. It transmits management messages and looks for and activates
newly connected slaves. During normal operation, the system keeps the
maximum cycle time of 5 milliseconds.
5.2 Configuration Mode
The configuration mode serves to configure the AS-i circuit.
Pressing the “MODE” button for at least five seconds switches the gateway to con-
figuration mode. While in configuration mode, the yellow “PRJ” LED lights up.
The system then displays one after the other all detected slaves at a speed of two
per second. If the display is empty, no slaves were detached on the AS-i circuit.
If the AS-i circuit is insufficiently powered (“AS-i” does
not light up), the master remains in the off-line phase.
1. Activation phase and the start of normal operation maybe so short that the numbers can not be seen in the display.
2. Activation phase and the start of normal operation maybe so short that the numbers can not be seen in the display.
In the configuration mode, all recognized slaves are activated even
when the desired and actual configurations do not match.
