Material number 050001948-02 identifies the PP2MB1/2 mainboard used within the B&R Power Panel 400 service environment. Because it is an internal board rather than a complete panel order number, the host Power Panel identity remains essential during replacement selection.

Power Panel 400 devices combine control and visualization functions and can use CompactFlash storage. B&R documents the PP400 platform as a fanless product family with control and motion integration, so stored application media and machine-specific configuration should be protected before board-level service.

• Retains the printed PP2MB1/2 board designation and 050001948-02 material identity for service matching.
• Belongs to the Power Panel 400 platform that integrates control, operation and visualization tasks.
• Works within a PP400 architecture that can be programmed and configured with Automation Studio.
• Relies on the host panel assembly for display, operator controls, enclosure and external connections.
• Requires machine-specific CompactFlash and application handling to be treated separately from the bare board.
• Supports a repair strategy centered on exact host-panel and board-revision identification.

• Maintenance of an installed Power Panel 400 whose internal PP2MB1/2 board has been identified.
• Board-level repair where the complete panel order number and machine application are available.
• Recovery planning for legacy machine controls that combine HMI and controller functions.
• Spare-board evaluation based on material label, connector arrangement and host-panel model.
• Service preparation that preserves the original CompactFlash image before hardware work begins.

• Treat 050001948-02 as a legacy service component and record both the board label and complete Power Panel order number.
• Power down the panel before handling CompactFlash media or internal hardware.
• Create a verified read-only image of the installed CompactFlash before exchange whenever the machine owner permits it.
• Retain the exact Automation Studio project and runtime version because the development environment alone does not recreate a machine application.
• After service, validate boot behavior, visualization, controller execution, fieldbus links and retained machine parameters.

Is 050001948-02 a complete Power Panel order number?

No. It identifies the PP2MB1/2 internal board, so the full host-panel order number must also be recorded.

Why is the CompactFlash card important during replacement?

Power Panel 400 installations use CompactFlash for the operating environment and application storage, making a verified backup central to recovery planning.

Can an empty CompactFlash card restore the machine automatically?

No. The machine-specific runtime, application and parameters must come from a valid backup or the machine builder.

Which software environment is associated with PP400 control projects?

B&R Automation Studio is used for uniform configuration and programming of control and visualization projects.

What information should accompany a PP2MB1/2 enquiry?

Include photographs of both board labels, the complete Power Panel model, connector layout, CompactFlash information and the observed fault.

Should the CompactFlash card be removed while the panel is powered?

No. The host device should be fully powered down before CompactFlash or internal board handling.
