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.
Table 12: Numerical value – visualization of timing relay times
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.
Figure 161: 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)
