Visualization with Pico GFX-70 5-21
Figure 5.15 Output formats
Screen 2 - Screen 2 shows a simple example of the visualization of timing relay
times using the function block parameter (FB parameter) from the Associated
variable tab. The screen contains three numerical values. These are associated
with the QV output of timing relay T04.
In order for the values to be displayed meaningfully, “ms” (milliseconds) is
entered in the Unit of measure field in the Number range/format tab.

Table 5.16 Numerical value – visualization of timing relay times
Numerical value 1: Start value of the timing relay T04
FB parameter: I2 (zero as input I2 is not assigned with on-delayed
relays!)
Numerical value 2: Setpoint of the timing relay T04
FB parameter: I1 (4000 as input I1 is assigned with the constant 4 s
(= 4000 ms) in the function block editor)
Numerical value 3: Actual value of the timing relay T04
FB parameter: QV (display of value present at the function block
output)
