Example

C# Implementation:

NetVars srCodesysNetVars = new SRCodesysNetVars();
srCodesysNetVars.IPAdress = "192.168.178.34";
srCodesysNetVars.CobID = 1;
ArrayList readValues;
Console.WriteLine("Received Values:");
srCodesysNetVars.dataTypeCollection.Add(new CDataTypeCollection(EasyNetVars.DataTypes.inttype));
srCodesysNetVars.dataTypeCollection.Add(new CDataTypeCollection(EasyNetVars.DataTypes.dinttype));
srCodesysNetVars.dataTypeCollection.Add(new CDataTypeCollection(EasyNetVars.DataTypes.stringtype,90));
srCodesysNetVars.dataTypeCollection.Add(new CDataTypeCollection(EasyNetVars.DataTypes.realtype));
readValues = srCodesysNetVars.ReadValues();
Console.WriteLine(readValues[0].ToString());
Console.WriteLine(readValues[1].ToString());
Console.WriteLine(readValues[2].ToString());
Console.WriteLine(readValues[3].ToString());
