//
// Required for Windows Form Designer support
//
InitializeComponent();
//
// TODO: Add any constructor code after InitializeComponent call
//
string strPCName = "";
string strOPCServer = "SWToolbox.TOPServer";
string strTag = "
Channel_1.Device_1.TagArray_1";
string strAccessPath = "";
try
{
//
//create our array of values we want to write to the tag
int[] values = new int[]{0, 1, 2, 4, 5, 6, 7, 8, 9, 10};
//
//define our OPC Web Client objects
EASYOPCDALib.EasyDA objOWC = new EASYOPCDALib.EasyDAClass();
//
//now to do the write
objOWC.WriteItemValue(
strPCName,
strOPCServer,
strTag,
strAccessPath,
values);
//
//display a message
MessageBox.Show("Tag write a success!");
//
//clean-up
objOWC = null;
}
catch(Exception ex)
{
MessageBox.Show("Error: " + ex.Message.ToString());
}
