Product Introduction
B&R 4D1042.00-090 PANELWARE Display Module
The B&R 4D1042.00-090 is a monochrome LCD display module designed for the B&R PANELWARE industrial HMI system. It provides a 4-line, 20-character display with 8.0 mm character height, using black characters against a yellow background with LED backlighting. The module operates on 24 VDC and displays machine operating information, status messages, and process data.
Its relatively large character size makes the B&R 4D1042.00-090 suitable for operator interfaces where clear text presentation matters more than graphical visualization. For maintenance teams supporting legacy PANELWARE installations, replacing a failed display can help retain the existing operator-interface arrangement without immediately undertaking a complete HMI migration. Controller compatibility must be checked before installation.

Application Scenarios & Field Pitfalls (The Engineer’s Perspective)
Engineering Pain Point
A failed operator display can create problems beyond simple visibility. On an older production line, operators may lose access to machine status messages, alarm descriptions, or operating instructions even though the underlying controller remains functional.
The B&R 4D1042.00-090 addresses this type of maintenance requirement in PANELWARE installations. However, replacing the display is not automatically equivalent to restoring the complete HMI system. The controller, display connection, configuration, and power supply must all be checked.
Typical Applications
- Manufacturing: Machine status and operating-message display on legacy production equipment.
- Packaging Industry: Operator information and machine sequence messages on automated packaging lines.
- Process Manufacturing: Local equipment status indication and process-message presentation.
- Material Handling: Operator-facing status information on conveyor and material-transfer systems.
Technical Pitfalls to Avoid
1. Do not confuse display compatibility with physical compatibility.
The 4D1042.00-090 belongs to the PANELWARE display family. A matching panel cutout or mounting arrangement does not establish electrical or controller compatibility. Verify the controller model, connection arrangement, and applicable hardware documentation before ordering a replacement.
2. Check the 24 VDC supply under operating conditions.
The published current consumption is 180 mA at 24 VDC. Measure the supply at the module connection rather than relying exclusively on the power supply’s front-panel indication. Loose terminals, voltage drops, and deteriorated wiring can produce intermittent display failures.
3. Inspect the display and surrounding hardware before replacement.
Older PANELWARE installations may have accumulated dust, moisture exposure, and connector oxidation. Isolate power before disconnecting the display, observe ESD precautions, and inspect the mating connections. A replacement module will not correct an underlying controller or wiring fault.
Field recommendation: Record the existing module’s complete part number, housing color, connector arrangement, and controller identification before approving a replacement. Do not assume that a visually similar PANELWARE display is a direct substitute.
Related Products
The following models belong to the B&R PANELWARE display family or provide related system functions. They are useful references when maintaining older installations.
4D1022.00-090
PANELWARE 2 × 20-character LCD display with 5.0 mm characters. Smaller display format for installations requiring fewer text lines. Not a direct display-format replacement for the 4D1042.00-090.
4D1042.00-590
Alternative PANELWARE 4 × 20-character display with black housing. Similar display format and character height; verify mounting and connection compatibility before substitution.
4D1044.00-090
PANELWARE 4 × 40-character LCD display with 4.3 mm characters. Provides more text capacity per screen, making it suitable for applications requiring longer operating messages.
4D1044.00-590
Black-housing version of the 4 × 40-character PANELWARE display. A different housing configuration for installations designed around this variant.
4C2200.01-110
PANELWARE system unit associated with the display-system architecture. Relevant when investigating controller-side faults rather than replacing the LCD display alone. Confirm the specific system configuration.
4C1300.01-510
PANELWARE system hardware reference for controller-side maintenance and legacy equipment assessment. Verify the supported display configuration before pairing.
Related model identification is based on B&R PANELWARE product documentation. Similar series membership does not establish direct interchangeability.

Procurement and replacement note
The 4D1042.00-090 is an older PANELWARE product. Its original published datasheet dates to 2004. Confirm current production status and actual stock condition before purchasing; do not assume that a listed unit is new surplus or refurbished.
For incoming inspection, request:
- Clear photographs of the actual module and nameplate.
- Confirmation of the complete part number: 4D1042.00-090.
- Display illumination and character visibility test results.
- Verification of the 24 VDC operating condition.
- Confirmation of the physical condition of connectors and mounting points.
The important distinction: This is a PANELWARE display module, not a standalone PLC CPU or general-purpose HMI. Confirm the existing controller architecture before treating it as a replacement part.
