Visualization with Pico GFX-70 5-23
Figure 5.21 Extended analog value output
Screen 5 - Screen 5 shows an example of the output of analog values (here
IA3) on the display with the visibility option switched via I1 and I2. The
settings for this were defined on the Visibility tab. Two numerical values are
shown on the screen that output the analog value in different formats. These
values are associated with analog input IA3 which provides a Word type
variable for further processing.
Figure 5.23 Make invisible function
Screen 6 - Screen 6 shows a simple example of the display change using an
external trigger. In this example input I1 is the external trigger. The screen
contains two numerical values. These are associated with the output QV of
timing relay T08 which is a DWord type variable. The timing relay is run in a
loop from 0 to 10 seconds.
Table 5.22 Numerical value – analog value output with invisibility activated
Numerical value 1: Display of the analog value with the scaling range 0 to 10; two decimal
places; Unit of measure "V" (Volt); make number invisible via Boolean
operand I1; make contact bit logic (Visibility tab)
Numerical value 2: Display of the analog value with the scaling range –5 to +5; two
decimal places; Unit of measure "V" (Volt); make number invisible via
Boolean operand I2; make contact bit logic (Visibility tab)
Table 5.24 Numerical value – analog value output with display change via external
trigger input
General settings: Value range from 0 to 11000; unit of measure: s (seconds); scaling
range from 0 to 11, two decimal places; display change active;
detection via external trigger input
Left numerical value: Display of timing relay value T08,
I1 actuated: the numerical value flashes as the external trigger is set for
flashing display via Boolean operand I1
Right numerical value: Display of timing relay value T08;
I1 actuated: the numerical value is inverted as the external trigger is set
for inverted display via Boolean operand I1
