This is another possibility for writing arbitrary values to the PLC. You can create a slider control, enabling the user to move the slider and write values to the PLC. The slider can be a simple object as shown below, or it can be a complex scenario like moving items on a conveyor. Any graphical object on your screen can act as a slider.
Some example slider controls:
To activate this control, select your graphical item, navigate to the Write/Set command options in the Properties window, and select Slider.
You will be presented with the settings window:
In the dialog window you have to set:
- Tag – either manually or from the tag database by clicking on the ‘…’ button.
- Type – you can choose the orientation of the slider from Left to Right, Top to Bottom, or vice versa
- Min and Max – range of Tag value
- Length – the length of the slider movement in pixels
The following picture demonstrates how parameters correlate to one another:
