Hi,

Is it possible to set a time via an input box in the visualisation? So for example

VAR
Time1: TON;
Trig1: BOOL;
TimeVariable: ???;
END_VAR
Time1(IN:=Trig1, PT:= TimeVariable);

Where TimeVariable is the variable to set the time delay on the Time1: TON;. Can I edit TimeVariable via a Text Field Input configuration, WRITE TO VARIABLE?

If so, what sort of variable would I need to set TimeVariable to? When editing the variable via the text box, would the format of the input have to be something like "T#2s"?

Any help appreciated

Yes it is possible. One way to do it would be to declare your TimeVariable as type real.
For your visualization you can use a rectangle with the following settings
text = %0.3f seconds.
text variable = POU.TimeVariable. //POU is the name of your POU where TimeVariable is initialized.
OnMouse* (InputConfiguration) = Write a variable and setup the min/max and the input type.

Then your call to the TON FB would look like:
Time1(IN:=Trig1, PT:=REAL_TO_TIME(TimeVariable * 1000)); //time is in ms

Hope this helps.
