S10 Basics: Creating a Device

This very short article describes how to create a new device object and add it to the current project.

A common way to create a new device is using the device object factory. For instance the following snippet creates and adds a PLC device for the "CODESYS Control Win" PLC.

This example can be used for devices only. If you want to create other object types, e.g. POUs, please follow the instructions described in S9 Basics: Creating a POU.

private static readonly Guid GUID_DEVICEOBJECTFACTORY = new Guid("{84d12aa5-3225-473b-9df6-18af40889bdf}");

IDeviceRepository devrepo = ComponentManager.Singleton.InstanceFactory.GetSystemInstance(typeof(IDeviceRepository).FullName) as IDeviceRepository; 
IObjectFactory factDeviceObject = ComponentManager.Singleton.CreateInstance(GUID_DEVICEOBJECTFACTORY) as IObjectFactory; 
IDeviceIdentification devid = devrepo.CreateDeviceIdentification(4096, "0000 0001", "3.5.13.0"); 
IDeviceDescription devdesc = devrepo.GetDevice(devid); 
IDeviceObject devobj = (IDeviceObject)factDeviceObject.Create(new string[] { devid.Type.ToString(), devid.Id, devid.Version }); 

Guid guidDevObj = SystemInstances.ObjectMgr.AddObject(project.Handle, Guid.Empty, Guid.NewGuid(), devobj, "YourDevice", -1); 
factDeviceObject.ObjectCreated(project.Handle, guidDevObj);
