Hello,
I need to control a VC4 HMI using external buttons.
For now I found the WheelCountDatapoint (632ae997-cdf1-4ac1-95ad-a435ea2b8542) that might help me.
Using this, I am able for now just to navigate on the numeric Inputs, and to open the TouchPad but I can not modify the values (It is not possible to navigate in the touchpad).
I also need to press buttons but for now I can only navigate on numeric Inputs with “Input” on “TRUE”
I need to navigate in pages, press buttons and to change values (i will have 4 digital inputs for this)
If you have any ideas that might help to easy control the Interface is great.
Thank you!
Hi,
I’m not sure what do you wanna do, navigating page would be easy using changepage datapoint in VCobject, for changing values and selecting buttons you could use VISAPI and VcLib, it could take some time to develop this, but is a possibility.

Thank you for your answerer. I will put the HMI into a box and I will need to change page, press buttons and set parameters (numeric and string inputs) with 4 external buttons (up, down, enter, esc).
Ok, I think the easiest way to do this is using maybe this 4 buttons but one of them for changedatapoint (page) to move between pages, and other 3 with function WheelCountDatapoint and WheelEnterDatapoint, and use just controls that can be controlled by wheel, Numeric, Dropdown, ListBox, Slider and Alarm.
You could use also some bitmaps and buttons, but just to show status, not for operation.
If you have to use strings, if it is possible to have them already defined, you could use Dropdown or Listbox to select one.
