Replied by hcvoort on topic Byte[]
Dear Sir/Madam,

I bought your quick opc .NET library, and it works very well for me. In my PLC program a have some structure types which I want to monitor/read/write. When I monitor a structure I get back a Byte[44], so 44 bytes. How can I decode this? See my code below:

_client.SubscribeDataChange(endpoint, struct_Test, 1000, (object sender, EasyUADataChangeNotificationEventArgs eventArgs) =>
{
if (eventArgs.Exception == null)
if (eventArgs.AttributeData.HasValue)
Console.WriteLine(eventArgs.AttributeData.Value.ToString());
}, "");


Best regards,

Carsten Voort

Dear Sir/Madam,

I am using your quick opc for .NET library (I bought a license), and it works very well for me. In the PLC code I have some structure types which I want to monitor/read/write. When I monitor for a change, and get the Value it tells me that I received a Byte[44], so 44 bytes. How can I decode this? See my code below:

_client.SubscribeDataChange(endpoint, struct_Test, 1000, (object sender, EasyUADataChangeNotificationEventArgs eventArgs) =>
{
if (eventArgs.Exception == null)
if (eventArgs.AttributeData.HasValue)
Console.WriteLine(eventArgs.AttributeData.Value.ToString());
}, "");

Beste regards,
