In UAReadArguments, set ReadParameters to UA Read Parameters.FromDevice.

I can give more info but only in the evening or tomorrow, as I am currently traveling.

We need urgently to modify a C# code to read data fromdevice and not fromcache.

We are using this code, where have we to add the FromDevice parameter? We cannot find any example inside documentation.

// Single item
easyUAclient = new EasyUAClient();
attributeData = easyUAclient.Read(opcServerName, itemName);
return attributeData.Value;

//Multiple items
easyUAclient = new EasyUAClient();
UAReadArguments[] args = new UAReadArguments[itemNames.Length];
for (int i = 0; i < itemNames.Length; i++)
args = new UAReadArguments(opcServerName, itemNames);

ValueResult[] value = easyUAclient.ReadMultipleValues(args);
return value;
