4.5.2 Local Display of Analog Input Transducer Block Output
These screens should only be considered as measured value
indicators for configured transmitters.
• The screens are not used for commissioning or diagnostic /
troubleshooting purposes.
• Prior to full fieldbus configuration (transmitter assigned a per-
manent address, AI block(s) configured and scheduled for exe-
cution, etc.), the value displayed will not reflect the transducer
measurement. (Pre-configuration values will typically be 0).
4.5.2.1 AI Out Display Screens
The Analog Input Out values will be conditionally dis-
played as part of the “rotating” home menu screens.
The screens will be formatted as shown where # in the title
is the number of the AI block (1, 2, 3, or 4) and mmm is
one of: “Lvl”, “Vol”, “Ifc”, “IfV”, “---” depending on the
value of the associated AI block’s Channel parameter.
• For example, “AI1Lvl” would be the most commonly used
AI Out screen.
• “AI2---” would be displayed when the channel value is 0
[uninitialized] for AI block 2.
The Out value will be displayed subject to limitations nec-
essary for a 6-character display [999999 > Value > -99999].

Analog Input Out Values
To Be Displayed
Because the Model 705 transmitter has four Analog Input
blocks any or all of which may be used in particular applica-
tions, a Transducer block parameter controls which AI block
Out values will be displayed.
The fieldbus presentation of this parameter will be similar
to that shown at left (host system dependent).
Any or all (or none) of the AI block Out values can be
selected for display on the LCD.
The local LCD version of this parameter is shown different-
ly due to the limitations of the LCD:
LCD label: “AI Disp ”
The default value of the Local AI Display parameter will be
such that AI 1 Out is selected.
