"Uncertain measured value status" symbol
The backlit LCD display contains a bargraph (0-100) and arrows to indicate measurements
above or below the measurement range. Analog process values, digital status and failure
codes are displayed in the 7-segment area. Here up to 8 values can be displayed with a
alternating time between 2 and 20 seconds. Plain text can be displayed in the 14-segment
area (text is limited to 16 characters and is scrolled if needed (marquee text)).
The indicator also displays the quality of the measured value. If the status of the displayed
value is 'good' (quality code equal to or above 0x80), no symbol is lit and the indicator
remains in the normal operational state. If the status of the displayed value is 'uncertain'
(quality code between 0x40 and below 0x80), the 'Uncertain measured value status'
symbol is lit. If the status is 'bad' (quality code below 0x40), within the 7-segment area the
display will show "BAD-" and the channel number where the bad value is published. The
entered text continues to be displayed in the 14-segment area and the bar graph is not
shown.

PROFIBUS® technology
PROFIBUS is the open, digital communication system in factory and process automation
that is standardized for all applications. PROFIBUS communication is incorporated into the
international standards EN 50170 and IEC 61158. It replaces analog 4 to 20 mA
transmission technology on a broad basis.
PROFIBUS has been around for over a decade and has systematically evolved to become
the global market leader. With different protocol versions, interfaces and profiles, the
modular PROFIBUS communication system can be applied universally and, with PROFIBUS
versions geared towards specific industries, covers the wide range of requirements of
factory and process automation in equal measure.
Configuration information is available in the manual "Guidelines for planning and
commissioning, PROFIBUS® DP/PA, field communication" (BA034S). This manual is
