4.1.1 Addressing device connection
Modules are fitted with a specific plug for addressing devices. When inserting the addressing link, the
module is automatically cut from the field bus for as long as it is connected to the addressing device. This
way addressing is possible even after the system set-up and the connection of the field bus cable to the
AS-Interface.
To be able to address a MASI20 module, simply connect the addressing device to the addressing plug of
the module. Module addressing with a manual addressing device requires no auxiliary supply.
Refer to the device instructions to address the slaves.
Slaves are provided with the default address 0.

4.2 System configuration
The system setup is established during the configuration phase ; the master must be used in
configuration mode. In this mode, the master automatically recognizes the slaves connected to the bus.
The features of the system, the profiles (ID-, ID1-, ID2-, IO-Code) as well as the slave addresses are
stored by the master.
In case of system extensions that are not in conformity with the AS-Interface
specifications, it is possible that some slaves are not detected by the master.
As soon as the whole system is configured and the master is operating in "Protected mode"
the differences in relation to the configured system can be automatically detected by the master (e.g.
slave failures, damaged bus cable or system extensions.
System configuration can be performed by an addressing device or directly via the master. The
configuration procedures are different according to the selected mode.
