Openness application-level licensing and access control (the Openness firewall). Use when an app is denied access to TIA Portal, when a LicenseNotFoundException occurs, or when explaining what rights/licenses an Openness app needs. Distinct from the security skill, which covers project-internal UMAC roles.
Network and DriveCliq configuration for SINAMICS drives. Use when connecting/disconnecting DriveCliq ports, configuring PROFINET interfaces, and discovering IO system topology.
Walking TIA Portal Openness object trees schema-free using GetServiceInfos/GetService/GetAttributeInfos/GetAttribute, matching objects by Name+TypeIdentifier, traversing composition properties via reflection, preventing cycles, and deduplicating COM proxy visits. Use when writing code that compares, inspects, or mirrors two Openness object trees dynamically without prior knowledge of the schema.
Online connection and download operations for TIA Portal. Use when connecting to CPU devices via OnlineProvider, downloading PLC software, configuring connection modes, and handling passwords.
Foundational knowledge for ALL TIA Portal Openness development. Covers SDK DLL discovery, TypeIdentifier requirements, and core development prerequisites. This skill should be loaded alongside any other Openness skill.
Overview and index of all TIA Portal Openness skills in this plugin. Use when unsure which specific Openness skill applies, when asked what Openness skills/capabilities exist, for a general map of what the Openness Development plugin can do, or for meta-questions like "what are the skills for", "which skill should I use for X", "wofür sind die skills da". Not for actual implementation tasks — those should activate the specific skill listed below instead.
Live TIA Portal Openness integration-test and CI guidance. Use when building or running tests against a real TIA Portal installation, including firewall and runner setup; not for headless WPF tests.
Drive parameters for SINAMICS drives. Use when reading/writing parameters, BiCo wiring, accessing parameters by index or name, and manipulating parameter bits.
Performance design for TIA Portal Openness applications. Use when an app feels slow, when navigating deep object chains in loops, when deciding whether to cache Openness data, or when reading/writing many attributes at once.
TIA Portal PLC Data Types (UDTs / PlcType) — TypeGroup navigation, recursive search, UDT XML export structure (Section Name="None"), and Member attribute formats. Use when writing or reviewing C# code that accesses, searches, creates, or parses UDTs in PlcSoftware.TypeGroup.
TIA Portal Openness PLC Safety Administration object model (Siemens.Engineering.Safety). Use when writing or reviewing C# code that configures fail-safe PLCs via SafetyAdministration, SafetySettings, AssignmentOfBlockNumbers, or RuntimeGroup creation and reconciliation.
Safety commissioning for SINAMICS drives. Use when configuring PROFIsafe functions like STO and SImO, updating safety checksums, setting safety axis type, activating safety parameter bits, and managing acceptance tests.
UMAC security configuration in TIA Portal. Use when creating custom roles, project users, assigning device function rights, managing master passwords, checking project protection status, or configuring CPU protection/access-control level (PlcAccessControlConfiguration, PlcProtectionAccessLevel).
Session and project management for TIA Portal Openness. Use when working with TiaPortal instances, opening/closing projects, attaching to processes, archiving, and managing the project lifecycle.
SIMATIC SD block document format (.s7dcl / .s7res), the V21 Openness export/import API, and programmatic network insertion via round-trip export → text-edit → import. Use when writing or reviewing C# code that exports PLC blocks as SD documents, modifies network content, detects programming languages from SD syntax, inserts new networks, or re-imports modified blocks.
PlcSoftware root plus BlockGroup, TypeGroup, TagTableGroup, and ExternalSourceGroup object model. Use when writing or reviewing C# code that navigates or creates PLC software elements beneath a PlcSoftware or SW-Unit context.
TIA Portal SW-Unit (PlcUnit) patterns — isolated group hierarchies, PLC-wide search across root and all SW-Units, element creation inside a SW-Unit, Instance DB creation when the source FB lives in a SW-Unit, and placing a SW-Unit from a MasterCopy. Use when writing or reviewing C# code that searches for blocks/types/tag-tables that may be inside a SW-Unit, or creates elements in the correct group context.
Tags and tag tables management in TIA Portal. Use when accessing, creating, renaming PLC tags, exporting/importing tag tables to XML, and finding tags by name.
Technology Objects (TOs) for motion control in TIA Portal. Use when creating, finding, and configuring Technology Objects like speed axes, positioning axes, and setting TO parameters.
Telegrams for data exchange between SINAMICS drives and PLC. Use when configuring main telegrams, safety telegrams, changing telegram numbers, resizing telegram I/O, and inserting PROFIsafe telegrams.
Thread-safety and apartment model rules for TIA Portal Openness. Use when building multi-threaded Openness apps, background services, or MCP-style servers that receive concurrent calls, or when hitting cross-thread exceptions.
Creating a new TIA Portal Openness project from scratch — interviews the developer about the entry model (packaged add-in or standalone Openness EXE), and, only for a packaged add-in, its entry architecture (in-process or separate EXE entry point), attach point (project tree, devices & networks, project/global library, version control import/export, workflow) and options, then generates, builds and verifies the project. Use for requests like "create a TIA add-in", "new Openness project", "scaffold an add-in", "start a TIA Portal add-in project", "I need an Openness console app". This skill creates new projects only; migrating an existing add-in to another TIA Portal major version is outside its scope.
