6.3 Configuration Mode
The configuration mode serves to configure the AS-i circuit.
Pressing the “mode” button for at least five seconds switches the master to configu-
ration 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. If the display is empty, no slaves were detached 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 detected AS-i
slaves were projected before.
When delivered the AS-i/Modbus gateway is in configuration mode.
6.4 Protected Operating Mode
6.4.1 Switching to Protected Operating Mode
In the protected operating mode, only AS-i slaves that are projected and whose actual
configurations match the nominal configurations will be activated.
In the configuration mode, all recognized slaves are activated even
when the desired and actual configurations do not match.
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.
You leave the configuration mode 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 con-
figuration. Simultaneously the actual AS-i configuration is
stored as nominal configuration in the EEPROM.
If the system detects an AS-i slave with address zero on the AS-i, it can
not leave the configuration mode.
