Editing a string

[danmas74]

Hi,

Is it possible to edit a string. I want to have a text field that i will edit on the operator panel and transfer that string to my PLC.

The only object that i found who make the keyboard appears is the TextBob Object. But i don't know how to save the new value.

Thanks for your help

Create an AnalogNumeric component on your screen. Then on its InputValueChanged event take the value from that component and use C# to manipulate the string. Then assign the manipulated value to a tag. Have that tag be associated with a register in your PLC.

Code: Select all

		void AnalogNumeric3_InputValueChanged(System.Object sender, Neo.ApplicationFramework.Interfaces.Events.ValueChangedEventArgs e)
		{
			string myString = this.AnalogNumeric3.Value.ToString();
			myString += "_I_added_this";
			Globals.Tags.a_string.Value = myString;
		}

Thanks for the quick response.

the alphanumeric object is not good. I want the field to be a text.

Thanks

The AnalogNumeric Object has a Display Format property that can be set "String”, this allows me to use the full keyboard versus the numeric only version. I am using this in my current HMI tied to a screen "Alias" called a_Description which is configured as DataType String.

The object type dropped on the screen may be "AnalogNumeric" but so far it has worked quite well as a text entry box for me. I’ve been using it to implement the Description entry of my own “Preset Editor” (custom PresetsDB.sdf with Json Serialized data).

I have not tried to attach it to a Controller Tag that was configured as STRING<X>, but I think it should work; it’s worth a shot anyway.
