The set data value is retained until:
■ You change the active address in the Addressing operating mode,
■ You replace the AS-Interface slaves which have the same address but
different ID, ID2, or IO codes.
■ The addressing device is automatically switched off or manually switched

Reading data from the AS-Interface slave
To read the input data from the AS-Interface slave, briefly press the button. If

Complex communication protocols
The addressing device supports the following complex communication protocols:
■ AS-Interface slaves with the profile S-7.A.7 are detected as AS-Interface
slaves with extended addressing and 4 inputs and 4 outputs and are
correctly handled.
■ AS-Interface slaves with the Profile S-0.B and S-7.B are detected as AS-
Interface slaves and handled in accordance with AS-Interface at Work.
