Centering Siemens LOGO! 9 Text Labels Without Alignment

The LOGO! 9 Text Label inside an LCD Message block renders left-aligned text and provides no native center or right-alignment command. The display interface extends the established LOGO! message-display model; it is not a free-form text compositor. Treat alignment as a layout workaround, not as a missing formatting button that can be enabled.

Message-display rendering model

The term here means the Text Label function within an LCD Message block. This distinction matters because “text message” can describe several objects informally, while the reported limitation applies to this specific display element.

A text label supplies characters to a fixed display layout. Its editor does not expose paragraph-style controls comparable to those in a document editor. Text therefore starts at the left side of its available area. The absence of an alignment control is a product-interface limitation, not evidence of a damaged project, an incomplete installation, or a hidden label property.

The decision path begins by identifying the selected object. If it is an LCD Message text label, continue to the alignment-control check. If it is another display object, inspect that object’s own properties; the result described here does not establish how other objects behave.

Check 1: Selected display object

Check 1: expect the selected item to be a Text Label in an LCD Message block.

Do not search unrelated message settings for a justification command. First prove that the editable item is the text label itself. This prevents changes to message conditions, visibility logic, or surrounding graphics that cannot affect character alignment.

Check 2: Native alignment control

Check 2: expect no center or right-alignment button for the selected text label. The text should remain anchored to the left side when entered normally.

Repeatedly reopening the properties, reinstalling the editor, or recreating the same label will not add a control that the object model does not provide. That practice consumes commissioning time without changing the rendering rule.

Check 3: Workaround selection

Check 3: expect the required layout to fall into one of two workable branches: padded text for a simple visual offset, or an image for controlled visual placement.

Leading spaces modify the character data, so they produce a fixed offset rather than semantic centering. Any change in wording or rendered width can change the apparent position. An image converts the complete label into positioned visual content, which gives more control but removes the convenience of editing the wording as ordinary text.

Workaround implementation

Use padded text only when approximate placement is acceptable:

1. Open the applicable LCD Message block and select its Text Label.
2. Enter the final wording before adjusting its position.
3. Add leading spaces one at a time until the label appears at the required horizontal location.
4. Repeat the adjustment for every alternate string displayed by that label. A single padding value is not automatically valid for strings of different lengths.
5. Run the message on the target display and judge the rendered result there rather than relying only on the editor view.

Use the image branch when alignment must remain visually controlled:

1. Create an image containing the final wording at the required horizontal position.
2. Replace the text-based presentation with that image using the project’s available image workflow.
3. Keep the image dimensions within the intended display area and inspect it for clipping.
4. Create separate image assets for alternate wording or language variants that the application must show.
5. Record the editable source used to create each image so future wording changes can be reproduced consistently.

Do not use a screenshot that contains unintended background elements or scaling artifacts. The image should contain only the controlled visual content needed by the message layout.

Resolved-layout verification

1. Check 4: object reading. Expect the project to retain the intended LCD Message block and either the padded Text Label or the selected image replacement.
2. Check 5: default-state reading. Expect the complete label to appear at the chosen horizontal position without losing its first or last visible character.
3. Check 6: variant reading. Expect every alternate string, language variant, or image state to remain inside the display area. A failure here means each variant needs separate padding or a separately prepared image.
4. Check 7: target-display reading. Expect the physical LOGO! 9 display to match the accepted layout closely enough for the application. Use this reading as the acceptance result because the workaround controls appearance rather than adding native alignment semantics.
