Display a level as a number
Add a readable percentage below the bar inside the tank. The example still uses a fixed preview without a PLC connection.
1. Choose value output
Select Basic objects → Value (Wert), then Output (Ausgabe), not Input. Place beside the tank and double-click.
2. Set properties
Use name Fuellstand_Tank_01_Wert, initial value 50, dimensions 120 × 30, rotation 0 and opacity 100. Leave the extra label and process fields empty. X=280/Y=250 is an initial location, not the final position under the bar.
3. Configure percentage output
Open Convert PLC value: linear two-point scaling, raw 0–100, output 0–100, unit %, decimals 0, DEC and preview x=50. Preview must show 50%. Apply. Bar and numeric display are separate objects: set both previews to 50. Their proximity does not link data. Later live use needs matching sources and scaling.
4. Format readable text
Open Format text: System, 20 px, white #f1f5f7, Bold, Left alignment and no italics. The formatting preview may still show 0; use it to assess style, then check the actual value on the page. Apply both dialogs.
5. Position and save
Move the number below the bar with clearance from the tank outline. Adjust bar length if necessary. Left alignment is within the number object; move the whole object to center it visually. Keep rotation 0 independently of the bar. Check 50% and a half-filled bar, then save Ctrl+S.
6. Common questions
For a missing %, enter the unit in Convert PLC value. If output stays 0, set the PLC preview there, not only initial text. Separate previews are not automatically linked. These values are not plant measurements. Continue with volume formulas or setpoint input.
Keyboard shortcuts
Apply or close property dialogs, select objects on the canvas and leave any active text field before using an object shortcut.

- Ctrl+C / Ctrl+V — copy / paste
- Copies the selection and inserts an offset copy. Check names and process assignments afterward.
- Ctrl+X — cut
- Copies objects to the internal object clipboard and removes them from the page. Paste with Ctrl+V.
- Ctrl+A — select all
- Selects unlocked objects on the current page.
- Arrow keys — move precisely
- Moves the selection one pixel in the chosen direction within the page bounds.
- Shift+Arrow — next grid position
- Moves the selection in the grid direction using the page grid spacing.
- Ctrl+L / Ctrl+Shift+L — lock / unlock
