3.8 LCD Transducer block

The LCD Transducer block supports the Advanced Display. The block is used to configure the
Advanced Display connected to the SLG 700 transmitter. The block stores the LCD configurations,
and sends these values to the Display while the transmitter is powered up or restarted. The SLG 700
device supports up to eight LCD screen configurations.
ATTENTION
The initial configuration of LCD transmitter is configured to show eight screens
with Product Level, Distance to Interface, Interface Level, Distance to
Interface, Electronic Temperature, Vapor, Vapor Volume, Upper Product
Volume
The Display shows the available set of process variables, and all function block inputs/outputs. In
addition, the block reports the current device status and errors. If a function block parameter which is
not currently a part of the control strategy is selected, an error appears in the Display.

Execution

3.8.1. Advanced Display
The Advanced Display provides three formats, and describes the field in each of the three Advanced
Display formats namely, PV, Bar Graph, and PV Trend. Essentially, all three formats provide the same
information, but with the following differences:

PV

User configurable display shows the configured PV.

Bar Graph

User configurable 126 segment Bar Graph with range settings. The Bar Graph displays the
current value of the configured PV.

PV Trend

User-configurable display period from one hour to 24 hours. The chart displays minimum,
maximum, and average of the configured PV over the selected trend period.
The LCD Transducer block supports configuration of up to eight LCD screens on the Advanced
Display. The Display has a screen configured with default settings.
Transmitter Messaging
The transmitter messaging is a feature that allows message typed through host up to 64 alphanumeric
characters) which is sent to the Advanced Display. The message is shown on the Display interspersed
with the configured screens.
