Routed by tia-openness-roadmap. C# Openness implementation of device-level operations: enumerating devices, creating and deleting devices, plugging and moving device items, slot/subslot/module manipulation, hardware identifiers, addresses, channels, compiling hardware and software, device properties, and software container traversal.

tia-devices-general

Scope

Device-level engineering — full C# Openness implementation.

When the roadmap routes here, the entire solution is C#. Do not mix with Python wrapper calls. Always load tia-csharp-common first (done by roadmap).

Reference files

Load ONLY the reference file(s) relevant to the task. Do not load all files at once.

Reference file	Load when the task involves
`references/device-enumeration.md`	Listing, finding, or iterating devices; device groups; ungrouped devices; navigating DeviceItems
`references/device-creation.md`	Creating or deleting devices; TypeIdentifier format (OrderNumber, GSD, System)
`references/device-attributes.md`	Reading/writing device or device-item attributes; GsdDevice service; CustomIdentityProvider (App IDs); hardware catalog queries
`references/software-container.md`	Accessing PlcSoftware or HmiTarget from a device; SoftwareContainer service; dynamic object structure discovery
`references/device-item-operations.md`	Plugging, moving, copying, or deleting device items; enumerating device items; changing device/module type; module information and plug locations; bulk SetAttributes; PSC file export; extension rack connections; telecontrol datapoint CSV export/import; user-defined logo settings
`references/device-item-interfaces.md`	NetworkInterface service; IOController or IOConnector attributes (SyncRole, PnUpdateTime, PnWatchdogTime, PnDeviceNumber); AddressController; addresses (StartAddress, IoType, Length); hardware identifiers; HwIdentifierController; channels (ChannelComposition, IoType, ChannelAddress); normalized type identifiers; address object attributes (IsochronousMode, ProcessImage)
`references/networks-and-connections.md`	Opening the Devices & Networks editor (ShowHwEditor, ShowInEditor); querying PLC or HMI targets by iterating DeviceItems; address object attributes; accessing channels of a module from a network perspective

For tasks spanning multiple areas, load all relevant reference files before generating code.

Execution pattern

Access Project.Devices composition (or DeviceGroups / UngroupedDevicesGroup)
Find or create Device objects
Navigate DeviceItem hierarchy as needed
Access SoftwareContainer via GetService<SoftwareContainer>() when PLC/HMI software is needed
Use ICompilable for hardware or software compile (see tia-project-general/references/compile.md)
