Screen 2:
Screen 2 shows a simple example of the visualisation of
timing relay times using the function block parameter (FB
parameter) from the Associated variable tab. This screen
contains three numerical values. These are all associated
with the QV output of the timing relay T04.
Table 12: Numerical value – visualisation of timing relay times
To interpret the displayed values, “ms” (milliseconds) is
entered in the Unit of Measure area on the Number range/
format tab.
Figure: 159: Timing relay times
Numerical
value 1: Start value of the timing relay T04
FB parameter: I2 (zero, as input I2 is not
assigned for an on-delayed relay!)
Numerical
value 2: Set value 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 timing relay 04
FB parameter: QV (display of the value present
at the function block output)
Start value 0ms
Setpoint value 4000ms
Actual value 1452ms
