4 Special
Effects
In addition to creating loop displays, sequence displays and other operator displays, there
are special effects that can easily be created, which emulate many operator terminal units.
In many cases it may be possible to eliminate a separate operator interface device.
4.1 Marquee Messages
Lines 1, 2 and 6 on the display may be used for “marquee” type messages of up to 15
characters. This feature can be combined with Process Alarms and display scripts to
provide context-sensitive operator instructions. For example, to post a message that reads
“TURN OFF PUMP”, designate one of the Inputs in the Display Block as Data Type
ASCII. Then, in the Internal value field type the message to be displayed, in this case
TURN OFF PUMP
Although it is possible to use lower case letters in the display, it is not recommended
for reasons of legibility.
To display the message on Line 6:
1. Open the Inputs tab of the Display block and add an input as shown in the next figure.
Type the text to be displayed in the Initial data field. No Display Formats need to be
defined for this type of display.
