Addressing Mode

When the device is switched on by pressing the ADR button, it is automatically in the addres-
sing mode and the connected subscribers are displayed.
If a different mode is to be used first, press the MODE button until ADDR appears in the LCD.
The ADR button must then be pressed in order to detect the connected subscribers.
If the AS-Interface-Handheld does not detect any slaves, error message
F2 appears.
All detected subscribers are displayed in the lower part of the display (small numbers). For con-
ventional slaves neither the letter A nor B is displayed here. If new, Version 2.1 slaves are
used, an A or B next to the address indicates whether the given slave is slave A or slave B.
If several different subscribers are connected to the AS-Interface-Handheld, the display swit-
ches between conventional (no letters) A slaves and B slaves every 2 seconds.
The address of the slave which is to be written next (activated slave) flashes at a frequency of
2 Hz. Press the ADR button again to activate the next higher available address.
To activate a specific slave, set the desired address in the upper-right field using the
button. When one of the two buttons is first pressed, the RD display is extinguished. Then
press the ADR button.
An RD displayed to the left indicates that the activated address is being handled. In addition,
the activated address begins to flash in the lower field. The following example should help il-
lustrate this behavior:
