Hello,
i am trying to write OPC Client in c#. I get connected to the server but when I try to add a OPCGroup i get always exeption error: Value does not fall within expected range. I have already tried to add existing group and also empty group but without any result. Has someone of You ever experienced such a problem? Any ideas how to solve it? Thanks in advance

            {
                ConnectedOPCServer = new OPCAutomation.OPCServer();
                ConnectedOPCServer.Connect(textBox1.Text,"");

                ConnectedOPCServer.OPCGroups.DefaultGroupIsActive = true;
                ConnectedOPCServer.OPCGroups.DefaultGroupDeadband = 1000;
                ConnectedGroup = ConnectedOPCServer.OPCGroups.Add();
                ConnectedGroup.UpdateRate = 500;
                ConnectedGroup.IsSubscribed = true;
            }
            catch (Exception ex)

Hello Michal,

usually your group must have a Name/Tag like

ConnectedGroup = ConnectedOPCServer.OPCGroups.Add("Your_Group1");
