General

The General settings page covers system-wide configuration that applies across the entire project: language availability, audit logging, security policy, and project management.

Languages

Defines which interface languages are available for users to select in their profiles. Adding a language makes it selectable for individual users — it does not change the interface for everyone, and it does not change your project configuration in any way. Only the UI labels and menus change for users who select that language.

If your operators work in different languages, add all relevant locales here first, then each operator can choose their own language in their account settings. To add a language, click Add and select from the supported locales list. If a user’s selected language is later removed, they revert to the project default.

Translating texts

Next to Add New Language there are three more buttons:

Autofill translations with AI uses the AI provider that you set in AI Engineer, so that section has to be enabled and have a valid API key. There is no confirmation question — the translation starts as soon as you click the button, and a window shows the progress:

• Missing translations — the number of texts still missing in each language,
• Translations saved — texts that the AI translated and the project stored,
• Not translated — texts that the AI did not translate,
• Skipped (changed meanwhile) — texts that were changed while the translation was running.

When nothing is missing, the window reports All texts are already translated. Newly translated texts are saved in the project immediately, so create a backup in Settings → Backup before you translate a large project, and have the result checked by someone who speaks the language.

User Interventions

When enabled, every operator action that changes a value is recorded to the userLog with:

• The username of the operator
• The tag or object that was modified
• The previous and new value
• A precise timestamp

This creates a full audit trail of who changed what and when — important for regulated environments, shift handovers, and incident investigations. The userLog is only populated when this setting is enabled, so turn it on before operations begin if you need a complete record.

Storage — The retention period for the userLog, shown in years/months/days/hours (e.g., 1y 0m 0d 0h). Operator intervention records older than this limit are purged automatically. Adjust it on the Storage page.

Security

Anonymous Autologin — When enabled, the HMI loads without any login prompt. Anyone who can reach the gateway’s URL is automatically signed in and can interact with all HMI views and tag data. Intended only for physically isolated, trusted networks where access is controlled at the network perimeter.

Require Two Factor — When enabled, two-factor authentication (TOTP) becomes mandatory for all user accounts, not just those where 2FA is individually enabled. Turn this on to enforce a site-wide 2FA policy regardless of individual user settings.

Token Expire (hours) — How long a login session token stays valid after the last activity. Setting this to a short value (e.g., 1 hour) means idle sessions are automatically signed out. Increase it for operator workstations where re-authentication disrupts continuous operations.

User Authentication/Creation Token — A shared token used for programmatic account creation and authentication via the REST API. Click Set token to generate or set a value; click Clear token to revoke it. This token is separate from per-user API Tokens and is typically used only for automated provisioning workflows.

Startup Screen

The Startup Screen setting defines the initial view displayed to all users when they access the web server or HMI, before any per-user override is applied. Configuring a startup screen ensures users are immediately directed to the most relevant information after login — for example the main plant overview or a critical process dashboard.

To set the startup screen:

AI Engineer

AI Engineer brings artificial intelligence into the project design. It consists of two independent parts — you can use either of them or both:

• the built-in AI assistant, a chat panel directly in the Designer,
• the MCP server, through which you connect an external AI tool of your choice to the project.

Built-in AI assistant

The assistant understands the whole project — assets, tags, connections, graphics, logic and data — and turns your instructions into real project components. Describe what you want to build, change or find, for example “Create a view with a gauge for tag 1.Motor.Speed”.

Setting it up

Working with the assistant

The assistant opens from the AI Engineer tab on the right edge of the Designer. Write the request into the field at the bottom (Enter sends it, Shift+Enter starts a new line). While the assistant works, the panel lists the individual steps, for example Reading: views or Creating a tag, and then shows the answer. If a step fails, the assistant usually corrects it and tries again.

At the top of the panel you can start a new conversation and open the history of previous ones. Stop interrupts a running answer, and a conversation can be exported to a PDF.

MCP server

The MCP server publishes the project to external AI tools that support the MCP protocol (Claude Desktop, Claude Code, ChatGPT, Gemini, Cursor…). Such a tool can then read and edit the project in the same way as the built-in assistant, but from its own environment — useful when you want to combine the project with other work (files, web, version control) or to make larger batch changes.

Setting it up

"datatalk-project-designer": {
  "command": "npx",
  "args": ["-y", "mcp-remote", "http://localhost/mcpdesigner"]
}

What the AI tool can do

What it cannot do

• It does not see the result. The tool works with the drawing data, not with a picture of the screen — check layouts and colors yourself.
• It does not read or write live values of tags, manage users and permissions or delete the project. It designs the project; it does not control the running process.
• Its changes are saved immediately as well — make a backup first.

Which one to use

Delete Project

Permanently removes the entire project — all connections, tags, HMI views, equations, settings, users, and access configurations. The gateway resets to a blank state. This action cannot be undone.
