Portrait HMI panel orientation: order the portrait variant

Can you rotate a landscape operator panel to portrait in software?

No, not on a fixed-format panel: a 5.7-inch basic operator panel draws every screen in its native 320 × 240 pixel landscape format, and no project setting turns that LCD through 90 degrees, so portrait on this panel is a hardware variant you order.

The panel's display hardware and its device entry are built for one orientation. The project software, TIA Portal V14 in this class of project, addresses the panel through that device entry, so every screen draws landscape no matter how the layout is written. Forcing portrait without the hardware means drawing each object turned by hand, screen by screen, and keeping those custom graphics alive for the life of the machine. The next standard object drawn from the library lands back in landscape, and the work repeats at every layout change. The same rule bites on other kinds of screen: a signage player that lacks portrait rotation support cannot be talked into portrait from the content side either, which the article on a signage player that lacks portrait rotation support shows from the playback side.

What are the three ways to get portrait on an operator panel?

Three paths exist, and only the first two keep the panel you already specified: order the portrait variant of the same model, use a rotation the panel's own settings menu supports, or move to a panel family that sells the same resolution in both orientations.

Only the first path is a pure order. The second depends on a support list you have to read, and the third trades the model number for a supported route that does not depend on your model at all.

Does your panel model ship in a portrait variant?

Check the catalog for your exact model with Portrait appended to the name, and check the datasheet display line for a tall format such as 240 × 320 pixels; when both appear at your size, the variant exists and the decision is made.

Vendors name the variant plainly because the buyer has to pick it at order time. The landscape model and the portrait model share the family, the size class and the resolution; the difference is the direction the LCD is mounted and the format the device entry reports. A third check closes the loop: the device catalog of your project software has to list the portrait device, because the screens draw in the frame of the device you select. If your software version shows no entry for the portrait device, confirm that entry before the order goes in, or you are back on the hand-rotated rebuild of the first section.

When does a panel's own menu do the rotation?

Only when the maker lists it for your terminal. Some panels carry the rotation in the terminal menu, on a page such as Terminal Setting → Display → Orientation, where you pick the degrees; support is per terminal model, and earlier terminals in the same family can lack the mode.

The setting lives in the terminal's configuration menu, not in the project. One general-purpose panel family spells the path out: Terminal Setting → Display → Orientation, where you select the rotation in degrees. Two checks decide whether you can use it.

First, support is per terminal. Newer terminals in a family carry portrait while earlier compact terminals in the same family do not, so read the support list for your exact model.

Second, software portrait modes are tied to hardware. On one vendor's panel software, portrait mode needs one of the specific panel models the documentation lists as supported, and the documented route without that hardware is a third-party rotation utility, a workaround you then own for the life of the software. Attempt rotation on hardware with no support for it and the failure shows up at the graphics driver rather than in the project; the article on fixing a portrait mode driver error on an embedded Windows panel is one worked case. Published rotation methods are model-specific as well: a walkthrough of rotating a small basic HMI screen between portrait and landscape applies to that model, not to the panel beside it.

Worked example: how much fits a 240 × 320 portrait screen?

The same 76,800 pixels stood on end: a 240 × 320 portrait screen shows a 20-line alarm list where the landscape frame showed 15 lines, and the trade is 10 characters of width on every line.

Take the alarm and status list the tall cabinet actually has to show. The landscape frame is 320 pixels wide and 240 pixels high; the portrait variant is the same panel turned through 90 degrees, 240 wide and 320 high. Take a 16-pixel line height, a readable list size on this class of panel, and the classic 8-pixel-wide character cell.

Landscape: 240 ÷ 16 = 15 lines, and 320 ÷ 8 = 40 characters per line.

Portrait: 320 ÷ 16 = 20 lines, and 240 ÷ 8 = 30 characters per line.

The pixel count is unchanged, because 320 × 240 = 76,800 and 240 × 320 = 76,800. Portrait buys 5 more lines and trades away 10 characters of width on each line.

Now hold the real texts against it. The longest message on the machine is "Line 3 gearbox temperature high", 31 characters including spaces, one over the 30-character portrait line. Shorten it to "Line 3 gearbox temp high", 24 characters, and it fits with 6 to spare. The result: order the portrait variant, re-lay the list in the tall frame, and the 20-line screen holds every message on the machine.

What do you confirm before you order the portrait variant?

Five items, and each one comes from a document the supplier already prints: the variant name and order code, the display format, the portrait device entry in your project software, the portrait cut-out drawing, and the delivery date on the variant build.

1. The variant name and order code, exactly as the catalog prints them.
2. The display format on the datasheet, confirming the tall resolution you designed the screens for.
3. The portrait device entry in your project software; confirm it exists in your version before the order goes in.
4. The portrait cut-out drawing, with width and height swapped, so the door is cut from the portrait dimensions.
5. The delivery date for the variant build, asked in the same sentence as the order code, because portrait is the less common build of the two.

If the portrait order follows a failed panel instead of a new machine, the protocol side still has to match the PLC, and the article on replacing a failed PLC operator panel without a protocol mismatch covers that check.

What changes on the cabinet when you mount portrait?

The footprint turns through 90 degrees: the panel's width and height swap, so the door cut-out must be drawn tall, and a connector that exited below the panel exits sideways. Check the portrait cut-out drawing before the door is cut.

The portrait variant is the same panel assembly mounted with the LCD turned, so the datasheet prints a second cut-out drawing for it. Cut the door from that drawing, not from the landscape drawing turned by hand; the corner radii and the clearances are printed for the portrait build. Plan the service loop for the new geometry: any cable that used to drop below the panel now runs out of the side, so leave access on that edge. Do the fit arithmetic before the plate goes to the cutter; the article on checking an HMI portrait panel fit before making changes walks that check step by step, cut-out against the door opening.

When do you pick a different panel line instead?

When the catalog has no portrait variant for your model and the maker does not list portrait support for your terminal. Move to a panel family that offers the same resolution in both orientations, or cover the job with a separate portrait notice screen.

Compact panel families exist that sell one resolution in both orientations: a 4.3-inch family with a portrait-landscape mode mounts horizontally or vertically to fit the space, and larger lines list portrait as a factory option, for example a 15-inch HMI offered with portrait orientation options. Make the change before the enclosure is ordered, because a bigger portrait screen also means a bigger cut-out.

If the tall screen is really a status or notice board, not a process HMI, skip the operator panel question and mount a signage display in portrait beside the machine; we sell displays for exactly that job, and the displays category is the place to start. For a screen that serves a building instead of a machine, the elevator screens guide lists the checks to sort out before you buy, orientation and cut-out among them.

Recommendation: If your panel model appears in the catalog as a portrait variant at the same size and resolution, order that variant, select the portrait device in the project, and re-lay the screens in the tall frame; on a fixed-format basic panel that is the supported route, and it is the only one that holds up over the machine's life. If the model has no portrait variant, choose a panel family that sells both orientations at the resolution you designed for before the door is cut, and carry the tags and screen-switch logic across unchanged.
