Operating Modes

7.2.5 Display and Write Parameters

This operating mode is for test purposes only. It is not possible to store
or configure parameter values in a nonvolatile manner in the
AS-Interface master or slave.
A special feature of this operating mode is that the AS-Interface supply voltage is not switched
off following the read or write operation. Please note that this operating mode places a large
load on the battery.
First activate the slave to which you would like to write parameter values.
To switch on the Display and Write Parameters operating mode, press the MODE button until
PARA appears in the display. When this mode is switched on, the default parameters are dis-
played in the upper-right corner.
In this operating mode, the parameter values are not read from the
slave. When this operating mode is switched on, the default values are
displayed. If the ADR button is pressed again following the write opera-
tion to read the parameter values, this display shows the most recently
written values.
To write parameters, use the
buttons is first pressed, the RD display is extinguished.
Upon pressing the PRG button, the parameters are transmitted once to the slave and the WR
display appears in the display. As long as the activated AS-Interface slave is connected to the
AS-Interface-Handheld or as long as the PARA operating mode is switched on, the slave func-
tions using the written parameter values. If the connection is interrupted or the operating mode
is changed, the values are lost.
Due to the device structure, pressing the MODE button first switches on
the PARA operating mode. Press the button again to switch on the
DATA operating mode. If you switch from the PARA operating mode to
the DATA operating mode, the AS-Interface voltage remains switched
on and the parameter value retained.

7.2.6 Displaying the Peripheral Fault Flag

The peripheral fault flag is an optional bit which indicates an error in the slave. This function is
only supported by Version 2.1 slaves. This flag can be read with the AS-Interface-Handheld.
Activate the slave from which you would like to read this bit.
