Essential Keyboard Shortcuts and Navigation Techniques in SIMATIC PCS 7 CFC Editor

To maximize engineering efficiency in SIMATIC PCS 7 Continuous Function Chart (CFC) editor, experienced automation engineers rely on standard keyboard shortcuts for navigation, zooming, and editing: 'Ctrl+U' toggles the full Overview displaying all sheets, while 'Ctrl+Shift+U' opens the single Sheet View. Use 'Ctrl+Arrow Keys' to navigate between adjacent sheets, 'Alt+Page Up/Down' for horizontal panning, and 'Ctrl+Page Up/Down' to switch between Chart Partitions (Worksheet A and B). Press 'Ctrl+K' to open the Block Catalog, 'F3' to insert global addresses, 'Alt+I+X' for textual interconnections, and 'Ctrl+F' to toggle online Test Mode.

Executive Summary

Engineering large-scale process automation applications in SIMATIC PCS 7 involves manipulating hundreds of Continuous Function Charts containing complex algorithmic interconnections, channel drivers, and technological blocks. Relying exclusively on mouse clicks to navigate menus, zoom between levels, open catalogs, and trace signals substantially slows engineering productivity and increases ergonomic strain. Mastering the built-in keyboard shortcuts of the CFC editor dramatically accelerates chart creation, online commissioning, and troubleshooting. This reference article consolidates the most effective keyboard shortcuts across view navigation, object insertion, block manipulation, and online test mode.

Architecture and Fundamental Mechanics

CFC Command Interface, Editor State Handling, and Shortcut Groupings:

View Modes and Zooming Shortcuts:
Ctrl + U (Overview View): Instantly switches the editor from single-sheet zoom to the macro view showing all 6 sheets (or configured sheet count) simultaneously. This enables rapid structural appraisal of signal flow.
Ctrl + Shift + U (Sheet View): Zooms into the currently selected sheet at 100% magnification for detailed block wiring.
Ctrl + Scroll Wheel: Zooms in and out dynamically centered on the mouse cursor.
Sheet and Partition Navigation Shortcuts:
Ctrl + Up / Down / Left / Right Arrow: Steps the viewport across the sheet grid (e.g. from Sheet 1 to Sheet 2 or Sheet 4).
Alt + Page Down / Alt + Page Up: Scrolls horizontally across the active sheet canvas.
Ctrl + Page Down (Next Partition): Advances from Worksheet Partition A to Worksheet Partition B.
Ctrl + Page Up (Previous Partition): Returns from Worksheet Partition B to Worksheet Partition A.
Object Catalog, Insertion, and Interconnection Shortcuts:
Ctrl + K (Catalog): Toggles the floating Block and Chart Catalog pane, allowing quick drag-and-drop or search of function blocks.
F3 (Insert Address): Opens the address entry dialog to connect a block terminal directly to a global operand (e.g. IW, QW, M, or Symbol).
Alt + I + X (Insert Textual Interconnection): Initiates a textual interconnection to an external chart or block not yet created.
Delete: Deletes the currently selected block, line, or interconnection.
Online Commissioning and Diagnostic Shortcuts:
Ctrl + F (Test Mode / Monitor): Toggles online test mode ('Glasses' icon) to monitor live process values from the CPU.
F1: Launches context-sensitive HTML help for the selected function block type (e.g. MonAnL, PidConL).
Ctrl + F4: Closes the active CFC window.
Ctrl + S: Saves chart modifications.

Step-by-Step Implementation Procedure

Practice Macro-to-Micro View Navigation:
* Open any CFC chart.
* Press Ctrl + U to inspect the entire chart overview.
* Click on Sheet 3, then press Ctrl + Shift + U to zoom into Sheet 3.
* Press Ctrl + Right Arrow to step across into Sheet 4.
Accelerate Block Placement and Wiring:
* Press Ctrl + K to open the Block Catalog.
* Use keyboard search to locate a block (e.g. And04), then press Enter to place it onto the sheet.
* Select an input pin and press F3 to immediately open the Symbol/Address dialog without right-clicking.
* Enter the process symbol name and press Enter to complete the connection.
Multi-Partition Traversal:
* If the chart has an overflow partition (Worksheet B), press Ctrl + Page Down to switch partitions instantly.
* Press Ctrl + Page Up to return to Partition A.
Commissioning with Test Mode and Block Help:
* While connected to a CPU or S7-PLCSIM, press Ctrl + F to engage live monitoring.
* Select any block and press F1 to display its official pin documentation, parameter ranges, and algorithmic descriptions.

Verification

In an active CFC editing session, execute each shortcut sequence sequentially:
* Ctrl+U -> switches to overview.
* Ctrl+Shift+U -> zooms to single sheet.
* Ctrl+K -> toggles catalog pane.
* Alt+Page Down -> scrolls rightward.
* Ctrl+F -> engages online monitoring.
Confirm that each command executes immediately without lag or dialog interruptions.

Limitations and Operational Precautions

Keyboard shortcuts are effective only when the CFC chart window holds active input focus. If a dockable window (such as the Block Catalog or Process Object View) holds cursor focus, certain navigation shortcuts may behave according to that child window's internal key bindings. Key mappings cannot be arbitrarily remapped in the standard STEP 7 / CFC options dialog.
