Fig. 13: LC display of the field indicator
Item 1: bar graph display in increments of 10% with indicators for underranging (item 1a) and overranging (item 1b)
Item 2: measured value display, digit height 26 mm (1.02"), status indication "Bad measured value status"
Item 3: 14-segment display for units and messages
Item 4: 'Communication' symbol
Item 5: 'Parameters cannot be modified' symbol
Item 6: '%' unit
Item 7: '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 will be
displayed in the 7-segment area. Here up to 8 values can be displayed with a alternating time
between 2 to 20 seconds. Plain text can be displayed in the 14-segment area (text is limited to up
to 16 characters and will be scrolled if needed).
The indicator also displays the quality of the measured value. In case the status of the displayed
value is 'Good' (a value equal to or above 0x80), no symbol is lit and the indicator works in normal
operation. If the status of the displayed value is 'Uncertain' (value between 0x40 and 0x7F), the
'Uncertain measured value status' symbol is lit. If the status of the displayed value is 'Bad' (value
below 0x40), the display will show within the 7-segment area "bad-" and the channel number
where the bad value is published. This channel number can also be found in the 14-segment area.
5.3 FOUNDATION Fieldbus™ technology
The FOUNDATION Fieldbus™ (FF) is a purely digital, serial communication system that connects
fieldbus devices (sensors, actuators), automation and process control systems with each other. As a
local communications network (LAN) for field devices the FF was primarily designed for the
requirements of process technology. The FF thus forms the basic network throughout the hierarchy
of a communication system.
Please refer to Operating Instructions BA 013S/04/en “FOUNDATION Fieldbus Overview:
Installation and Commissioning Guidelines” for configuration information.
