Product Introduction
The B&R 4P3040.00-490 is a Power Panel PP41 that combines operator interaction and machine-control hardware in one panel-mounted unit. Its 5.7-inch QVGA monochrome LCD is paired with 8 softkeys and 32 function keys, while the integrated 2003 CPU provides the control platform. The hardware includes 700 KB SRAM, 1.4 MB FlashPROM, one PCMCIA slot, RS-232 and electrically isolated CAN communication.
From a maintenance perspective, the important point is that this is not simply an HMI display. The 4P3040.00-490 also contains 10 digital inputs and 8 digital outputs, allowing it to participate directly in machine-control architecture. Its six adapter-module slots provide further hardware expansion, while the 24 VDC supply and IP65-rated front are suited to panel installation.

Application Scenarios & Field Pitfalls — Engineer’s Perspective
Engineering Pain Point
The 4P3040.00-490 is often described online as a touchscreen HMI. That description is misleading. B&R’s own documentation identifies the PP41 interface as a key-operated panel with 8 softkeys and 32 function keys, combined with an embedded CPU and I/O.
Typical Applications
- Machine control panels — operator commands, machine status and local diagnostics.
- Packaging and production machinery — integrated HMI and discrete machine I/O.
- Legacy B&R control systems — replacement of existing PP41 panels without redesigning the entire control architecture.
- Compact automation stations — applications requiring operator interface, CPU, communication and discrete I/O in one assembly.
Technical Pitfalls to Avoid
- Do not treat it as a standalone display. The integrated 2003 CPU and I/O are part of the system architecture. A replacement requires consideration of the application/runtime environment, not only screen dimensions.
- Do not assume touchscreen operation. The standard 4P3040.00-490 uses softkeys and function keys. Current descriptions that label it a touchscreen should not be used as the primary technical reference.
- Check the terminal blocks before installation. B&R specifies TB712 terminal blocks separately from the Power Panel itself. Missing terminal hardware can delay commissioning even when the main panel is available.
- Preserve the original software environment. B&R community documentation specifically notes that standard 4P3040.00-490 units and customized 4P3040.00-Kxx variants can require different hardware upgrade considerations.

Procurement Note
For a replacement B&R 4P3040.00-490, verify the complete material number rather than purchasing a visually similar panel. The critical compatibility points are the 2003 CPU configuration, Automation Runtime/application version, PCMCIA contents, adapter modules, digital I/O wiring, CAN network configuration, and installed terminal blocks.
B&R’s current product page still provides the original documentation for 4P3040.00-490, while secondary sources identify the model as discontinued.
Database classification: B&R 4P3040.00-490 = Power Panel integrated HMI/operator panel + 2003 CPU + digital I/O controller.
