Changelog

Classroom and reliability update. New Classroom interface for teachers and students, with clearer command results, an unread message badge and a network adapter chosen by the user. A new Web Setup shows the installation in six clear phases, opens only once and displays errors during installation. Signing in again with your account works after Sign out or a removed seat, and the licence choice stays on screen. The Licence page shows the device name and hardware identifier. The Copilot conversation survives a lost TIA Portal session and is resumed when the project is reopened. A clear message explains that TIA Portal must be installed when it is missing. GRAPH blocks keep compound transition conditions, conditioned actions and declared members. Simulated CPUs: state, start, stop and simulation options work with PLCSIM Advanced, including TIA Portal V21. WinCC Unified panels get real tag bindings. Clear messages when TIA Portal is busy, lost or waiting for an answer. Fixes a startup error that could block sign-in.

Reliability update. Opening and retrieving TIA Portal projects works again in the signed build, including UMAC-protected projects. A PLCSIM Advanced internal crash no longer closes T-IA Connect. PLC proxy stations stored in device folders are handled safely. Clear errors when the TIA Portal session is lost. Fewer interface freezes. Clearer API key errors with a repair alert. Web Setup repairs computers blocked with error 1213.

• New CPU configuration assistant and HMI device assistant, available to your AI client through MCP. • The Copilot now discovers the tools it needs progressively, for faster and more focused answers. • New operation history tab in the console. • Clearer message when a device name cannot be found; device names containing "+" are kept intact. • Batch tools now report exactly what was applied, including runs where nothing needed to change. • Generated FC and FB blocks automatically receive a free number. • HMI tag options are applied correctly and alarm trigger tags are verified. • Browser sign-in: clearer refusal messages and translated pages. • The installer now removes the previous version within the same installation.
