Arrays 2

[daoa80]

Help!!!

this is an example of a tag list that I have created seen in the Design view:

Tag Controllers
Name DataType AccessRight DataType EMCP1
SPNFMI_0 UNIT32 Read UNIT32 41511
....
....
SPNFMI_39 UNIT32 Read UNIT32 41890


1. I have to go through every tag (EMCP1 value) to get some info

2. Insted of manually changing the tag name, can it be done using an array,
e.g


for(int x=0; x < 40; x++)
{
value [x] = (Globals.Tags.SPNFMI_[x].Value>>5) & (0x7FFFF);
}

So when x=0, it will get the info from SPNFMI_0
when x=1, it will get the info from SPNFMI_1 and so on.


Any hints? is it possible?

I got this tip for concatinating strings to read tag values from the support guys in Sweden.
Just include the method GetGlobalDataItem in your code and these using statements.
using Neo.ApplicationFramework.Tools.OpcClient;
using System.Reflection

int number = 1;

decimal val = GetGlobalDataItem("Tag" + number.ToString()).Value.Decimal;

private GlobalDataItem GetGlobalDataItem(string propertyName)
{
PropertyInfo tagProperty = typeof(Neo.ApplicationFramework.Generated.Tags).GetProperty(propertyName);
if(tagProperty == null)
return null;
else
return tagProperty.GetValue(Globals.Tags, null) as GlobalDataItem;
}

Does it work for you?
I've been trying with no success; found another link with different approach:

See below for a working example on Screen1 with a button.

Code: Select all

namespace Neo.ApplicationFramework.Generated
{
    using System.Windows.Forms;
    using System;
    using System.Drawing;
    using Neo.ApplicationFramework.Tools;
    using Neo.ApplicationFramework.Common.Graphics.Logic;
    using Neo.ApplicationFramework.Controls;
    using Neo.ApplicationFramework.Interfaces;
    
	using Neo.ApplicationFramework.Tools.OpcClient;
	using System.Reflection;
    
    public partial class Screen1
    {
		
		void Button1_Click(System.Object sender, System.EventArgs e)
		{
			//Number at end of tag.
			//Tag name should look like Tag1, Tag2, TagX
			int number = 2;

			decimal val = GetGlobalDataItem("Tag" + number.ToString()).Value.Decimal;
			
			this.Text1.Text =  val.ToString();
		
		}
		
		private GlobalDataItem GetGlobalDataItem(string propertyName)
		{
			PropertyInfo tagProperty = typeof(Neo.ApplicationFramework.Generated.Tags).GetProperty(propertyName);
			if(tagProperty == null)
				return null;
			else
				return tagProperty.GetValue(Globals.Tags, null) as GlobalDataItem;			
		}
    }
}
