Overview: Screen Real Estate in the Unified Engineering Framework
SIMATIC TIA Portal (Totally Integrated Automation Portal) consolidates PLC, HMI, drive, motion, and safety engineering into a single environment. That integration trades visible desktop area for functional density: the Project tree, Inspector window, Task cards / Favorites, Detail view, Output window, References, and the multi-document editor all share the same physical screen. On a 15.6-inch laptop or single 24-inch 16:9 monitor, the usable code surface can drop below 30 percent of the display unless the workspace is intentionally configured.
This reference consolidates the configuration paths, keyboard accelerators, and version-specific features that recover usable space for the LAD, FBD, STL, SCL, GRAPH, and HMI editors used on S7-1200, S7-1500, ET 200, and SIMATIC HMI projects. All procedures assume a TIA Portal installation on Windows 10 / Windows 11 (64-bit) with a current Siemens Industry Online Support license.
Editor Anatomy: What Occupies the Workspace
Before reconfiguring, identify the chrome elements that consume the editor window. The default installation of TIA Portal places the following surfaces on every project document:
| Element | Default position | Approx. footprint (1920×1080) | Hide path |
|---|---|---|---|
| Title bar (block name duplicate) | Top | ~32 px | Fixed by OS; TIA Portal V17+ exposes tabbed document mode that suppresses the legacy duplicate |
| Menu bar | Top | ~24 px | Cannot be hidden (Ribbon mode not available in TIA Portal) |
| Editor toolbar | Below menu | ~36 px | Compact view (V17+) collapses to icons-only |
| Project tree | Left dock | ~280 px wide | View → Project tree, or pin/unpin via arrowhead |
| Inspector window | Right dock | ~320 px wide | View → Inspector, or pin/unpin |
| Task cards / Favorites | Bottom dock | ~180 px tall | View → Task cards |
| Detail view | Bottom dock | ~140 px tall | View → Detail view |
| Output window | Bottom dock | ~120 px tall | View → Output |
| References (cross-reference) | Inspector sub-tab | Shares Inspector | Inspect → References → Show/hide |
| Library panel (faceplates) | Right slide-in | ~360 px wide | View → Library, or X button when expanded |
The "block name appearing twice" observation in older versions corresponds to the legacy MDI mode where the document title appears both in the window title bar (operated by Windows) and inside the TIA Portal document header. Enabling the tabbed document interface removes the inner header entirely.
Core Panel Configuration
Most panel visibility is controlled from the View menu. The four pinned zones (left, right, bottom-left, bottom-right) each accept auto-hide behavior via the pin/needle icon at the top of the panel header.
Procedure 1 — Hide Task Cards / Favorites Bar
- Open any LAD / FBD / SCL / GRAPH editor.
- Select View → Task cards. The check mark clears; the bottom panel collapses.
- Reopen via the keyboard accelerator
Ctrl + Alt + Twhen instructions are needed, or use the Instructions pane inside the Inspector window as a permanent substitute.
Procedure 2 — Auto-Hide Inspector and Project Tree
- Hover the panel header; the pin icon (📌) appears.
- Click the pin. The panel slides to a thin vertical or horizontal sliver.
- Hover over the sliver to expand; move the cursor away to collapse.
- For permanent hide: click the X or use View → Inspector.
Procedure 3 — Reset Workspace Layout
- Window → Layout → Reset layout returns all panels to factory defaults.
- Per-document layouts can be saved with Window → Save current layout as default for this type of editor (V17.0.1.0 onward).
%LOCALAPPDATA%\Siemens\Automation\<PortalVersion>\Layout. Deleting this folder resets the entire user UI; back up the folder before resetting when troubleshooting corruption symptoms such as grey bars that do not respond to menu commands.Window Layouts: Docking, Floating, and Multi-Monitor
TIA Portal uses a standard docking framework. Each panel header supports drag-and-drop to any of the four screen edges or detaches as a free-floating window. Floating windows can be moved to a secondary monitor without DWM (Desktop Window Manager) tearing on Windows 10 build 1903+ and Windows 11.
| Drag target | Result | Recommended use |
|---|---|---|
| Outer edge (screen border) | Docks against that edge | Inspector on right edge of secondary monitor |
| Inner panel edge (arrowhead) | Docks beside existing panel (creates stacked tabs) | Combine Detail view + Output window in one bottom strip |
| Center of monitor | Floating window | Libraries on dedicated monitor |
| Editor tab strip | Document tab inside the editor area | Side-by-side block comparison |
Recommended Multi-Monitor Topologies
- 24-inch primary + 24-inch portrait secondary: Portrait orientation on the secondary monitor adds ~100 percent vertical pixels for LAD/FBD networks. Use the Windows display settings to rotate only the secondary display.
- 15.6-inch laptop + 27-inch primary: Run TIA Portal maximized on the 27-inch monitor, set the laptop as the secondary display for HMI tag references and PDF manuals.
- Ultra-wide 3440×1440: Single monitor with the Editor maximized still provides ~1440 vertical pixels, sufficient for 6–8 LAD networks without scrolling.
Keyboard Shortcuts for Navigation Efficiency
Minimizing mouse travel to toolbars recovers effective code area by reducing the time spent in non-editor regions. The following accelerators are documented in the SIMATIC TIA Portal Help under "Keyboard shortcuts for editors":
| Action | Shortcut | Minimum version |
|---|---|---|
| Open project | Ctrl + O |
V13+ |
| Save project | Ctrl + S |
V13+ |
| Compile (hardware/software) | Ctrl + B |
V13+ |
| Compile all | Ctrl + Shift + B |
V13+ |
| Download to device | Ctrl + L |
V13+ |
| Go online | Ctrl + K |
V13+ |
| New tab (MDI) | Ctrl + T |
V17.0 |
| Close current document | Ctrl + F4 |

V13+ |
| Step into (online) | F11 |
V13+ |
Ctrl + Tab to switch documents. In legacy MDI (V15, V16), only the Window menu or mouse clicks on the document icons switch documents.Compact View Mode and Toolbar Customization
TIA Portal V17.0 introduced a Compact view that reduces toolbar icon padding and removes the descriptive text labels. The mode is global and applied through the user settings.
Enabling Compact View
- Options → Settings → General → Appearance.
- Under View style, select Compact.
- Click OK; restart not required.
Compact view reduces the editor toolbar height by approximately 12–16 pixels and the project tree row height by approximately 4 pixels. On a 1920×1080 display this recovers roughly 8–12 percent of vertical space. The visual trade-off is reduced text legibility at <100 percent DPI scaling on Windows 10.
Toolbar Customization
The editor toolbar is fixed; tool icons can be added or removed through Options → Settings → LAD/FBD/SCL/GRAPH → Editor. Adding frequently used instructions to the toolbar reduces trips to the now-hidden Task cards panel.
Multi-Document Interface (Tabbed MDI) Configuration
Starting with TIA Portal V17.0, the document area supports a tabbed MDI similar to Visual Studio. Block names appear once on the tab rather than duplicated on both the title bar and a document header.
Enabling Tabbed MDI
- Options → Settings → General → Appearance → Document area.
- Select Tabbed under Document interface.
- Restart TIA Portal for the change to take effect.
Tab Placement (V18+)
TIA Portal V18 added tab placement options:
- Top (default)
- Bottom (frees the top 32 px; useful on portrait-orientation secondary monitors)
- Left (vertical tabs — best for ultra-wide monitors where horizontal space is not at a premium)
Favorites and Library Management
The Favorites bar (lower edge in legacy layouts) is the same data as the Library panel in the Inspector window. Users who need library access only occasionally should:
- Hide the Task cards / Favorites bar (View → Task cards).
- Pin the Library tab in the Inspector window instead.
- Use the keyboard accelerator
Ctrl + Shift + Lto summon the Library on demand.
For projects with extensive user libraries, create a user library (TIA Portal V14+ → Libraries → Master copies → New user library) and store it on a fast local SSD. The library index file is loaded into memory at project open; libraries larger than 1 GB degrade project open time on mechanical drives.
Cross-Reference and Reference Data
The cross-reference viewer historically opened in a separate window (V13/V14) and in V15+ is integrated into the Inspector. To reclaim the Inspector for properties, switch cross-reference to the References tab on demand. For whole-project references use Project tree → Common data → Cross-references which opens in its own document tab rather than occupying the Inspector.
Procedure — Project-wide Cross-Reference
- Right-click the project name in the Project tree.
- Choose Cross-references → Show.
- The result opens as a tabbed document (V17+) or as a separate window (V15/V16).
- Filter by Used / Unused / All via the toolbar dropdown.
Performance Configuration for Large Projects
UI responsiveness and workspace fluidity depend on hardware and TIA Portal options, not only on panel configuration. The following items affect how much of the screen is "wasted" waiting for repaints rather than actively editing code:
| Resource | Minimum (TIA V17/V18) | Recommended (S7-1500 projects > 500 blocks) | Notes |
|---|---|---|---|
| CPU | Intel Core i5-8400 / AMD Ryzen 5 2600 | Intel Core i7-12700 / Ryzen 7 5800X | Per SIMATIC TIA Portal V18 Installation Manual (entry ID 109773875) |
| RAM | 16 GB | 32 GB (64 GB for projects > 5000 blocks) | TIA Portal pre-allocates workspace above project size |
| Storage | SATA SSD 50 GB free | NVMe SSD 100 GB free | Project cache, libraries, and grafic framebuffer |
| GPU | Integrated HD Graphics 630 | Discrete NVIDIA T600 / AMD Radeon Pro WX 3200 | Drives HMI faceplate render performance |
| Display | 1920×1080 | 2560×1440 single, or dual 1920×1200 | Single ultra-wide avoids docking complexity |
TIA Portal Performance Toggles
- Options → Settings → General → Performance: disable Show animations.
- Options → Settings → HMI → Performance: reduce Zoom level for faceplates to 75 percent if the inspector-side faceplate preview slides in slowly.
- Disable Auto-save on long-running compile sessions; auto-save blocks the editor during write-back. Set the auto-save interval to 15 minutes or longer for projects > 2 MB.

| Version | Release year | Workspace-relevant feature |
|---|---|---|
| V15.0 | 2018 | Inspector window unified; cross-reference inline |
| V15.1 | 2019 | Library pinning in Inspector |
| V16.0 | 2020 | OPC UA server configuration merged; minor Inspector performance |
| V17.0 | 2021 | Tabbed MDI document area; Compact view style; reworked Favorites |
| V17.0.1 | 2022 | Per-editor-type layout memory |
| V18.0 | 2023 | Vertical document tabs; ProDiag integration without external tool window |
| V19.0 | 2024 | TIA Portal One collaboration overlay; dark theme (system-dependent) |
| V20.0 | 2025 | AI-assisted code suggestion panel that docks like Task cards and auto-hides after inactivity |
Projects saved in V17 cannot be opened in V15 / V16. For mixed-version teams, freeze the version on the lowest common install and apply only hotfix updates within that major.
Hardware and Windows Configuration
The operating system contributes to perceived workspace. Three settings consistently reclaim screen space:
- Windows taskbar: Move to the left or right edge of the primary monitor to add ~40 px of vertical pixels on a 1920×1080 panel. Use Settings → Personalization → Taskbar → Taskbar behaviors → Taskbar alignment.
- DPI scaling: At 125 percent Windows DPI scaling, TIA Portal toolbar icons render correctly but the Editor area is reduced proportionally. For dedicated engineering stations, use 100 percent scaling at native panel resolution.
- Display orientation: Rotate the secondary monitor to portrait for vertical LAD networks. TIA Portal respects OS rotation.
Windows Active Hours and Auto-Updates
Disable automatic restarts during engineering hours: Settings → Windows Update → Advanced options → Pause until. An unplanned reboot mid-compile corrupts the project cache; the recovery prompt on next open consumes additional editor real estate on top of the unexpected error.
Workspace Verification Checklist
After reconfiguration, validate the workspace against the following checklist before resuming programming:
- Open a representative block (e.g., OB1 Main, an FB with 10 networks, an SCL source file).
- Confirm only one instance of the block name appears in the editor chrome.
- Confirm Task cards are hidden; Library access still functions via
Ctrl + Shift + L. - Confirm Project tree and Inspector are auto-hidden or pinned to monitor edges.
- Switch between three blocks using
Ctrl + Tab(V17+). - Trigger a full compile (
Ctrl + Shift + B); confirm Output window appears only on demand. - Save the layout: Window → Save current layout as default.
- Close and reopen the project to confirm layout persistence.
Field-Proven Optimization Summary
For S7-1500 / S7-1200 projects exceeding 1000 program blocks or any project that includes WinCC Comfort / WinCC Professional faceplates, the following baseline configuration is recommended:
- TIA Portal V18 or newer on Windows 11 23H2
- Tabbed MDI enabled, tabs at the bottom or left
- Compact view enabled
- Task cards hidden; Library pinned in Inspector
- Project tree and Inspector docked to monitor edges with auto-hide
- Dual 24-inch 1920×1200 monitors, secondary in portrait
- 32 GB RAM, NVMe SSD, dedicated GPU
- Antivirus exclusions on the TIA Portal cache folder
- Auto-save interval set to 15 minutes minimum
The combination reduces reported edit-and-test cycle time on large projects and brings the usable code surface to roughly 55–65 percent of the primary monitor, depending on inspector activity.
How do I hide the Favorites bar in TIA Portal?
Open View → Task cards to toggle off the Favorites bar. Access libraries and instructions on demand with Ctrl + Shift + L, or pin the Library tab inside the Inspector window. The setting persists per user and per project.
Can TIA Portal be used efficiently on a single 24-inch 1920×1080 monitor?
Yes. Enable Compact view (V17+), tabbed MDI, auto-hide on Inspector and Project tree, and hide Task cards. Combined, these reclaim roughly 30 percent of vertical pixels. For larger projects or faceplate-heavy HMI work, a second monitor or an ultra-wide panel is recommended.
Why does the block name appear twice in TIA Portal V15 and V16?
The legacy MDI document area renders the block name in both the OS title bar and the TIA Portal document header. Upgrading to V17.0 or newer and enabling Tabbed document interface under Options → Settings → General → Appearance removes the duplicate.
What is the minimum hardware for TIA Portal projects larger than 1000 blocks?
Siemens specifies 16 GB RAM and an SSD for V17/V18; for projects above 500 blocks, recommend 32 GB RAM and an NVMe drive per the SIMATIC TIA Portal installation manual. A discrete GPU helps faceplate rendering on WinCC Professional.
How do I switch between open blocks with the keyboard in TIA Portal?
In tabbed MDI (V17+), use Ctrl + Tab and Ctrl + Shift + Tab to cycle documents. In legacy MDI (V15, V16), the Window menu lists open documents and accepts keyboard navigation. The OS-level Alt+Tab is intercepted by the editor's hosted document area and does not switch TIA Portal documents.
