Hi,
When setting the Alignment property of an IVariable (creating the variable in the Zenon project (IProject) with AddIn in C#), this exception is thrown (below). Also the Alignment property seems to not be editable in the Zenon editor either. This functionality is needed to control the byte order of strings when reading them over the Modbus protocol at a per variable level.
Is this a known issue? Any insight into fixing this issue would be helpful.
Exception:
[Scada.AddIn.Contracts.RuntimeException: Error HRESULT E_FAIL has been returned from a call to a COM component. ---> System.Runtime.InteropServices.COMException: Error HRESULT E_FAIL has been returned from a call to a COM component.
