Description
⚙️ Product Overview
The Bosch Rexroth IndraLogic VPP21 R911323940-123 is an industrial operating and display unit designed for machine visualization, operator control, and industrial automation applications.
The VPP21 platform combines an industrial operator terminal with a PC-based hardware architecture and can be used for visualization applications as well as IndraLogic-based PLC control. The VPP21 family is equipped with a 14-inch TFT display, providing an operator interface for machine status monitoring, parameter entry, diagnostics, and control functions.
The supplied model designation R911323940-123 should be matched against the existing installation before replacement, especially when maintaining an older Rexroth machine or control cabinet.

🖥️ Display & Operator Interface
The VPP21 platform uses a 14-inch TFT display for industrial visualization. Depending on the specific VPP21 hardware variant, the operator interface can be provided through a touchscreen or through a keypad-equipped configuration. The VPP21 documentation identifies dedicated variants for both touchscreen operation and keypad-based operation.
The operator interface can be used to display machine parameters, process information, alarms, diagnostics, and control screens. Side navigation keys are also used on applicable VPP21 visualization configurations.
💻 IndraLogic System Integration
The IndraLogic VPP21 is more than a conventional display panel. Its system architecture combines the IndraControl VPP21 hardware with IndraLogic software, real-time operating components, and visualization functions. This allows the platform to serve as an operator interface as well as a PC-based control platform in suitable applications.
For replacement projects, the installed software environment, PLC application, visualization project, storage media, and peripheral connections should therefore be checked in addition to the hardware part number.
🏭 Typical Applications
- Machine tool HMI
- Industrial machine visualization
- Production-line control
- Manufacturing automation
- Motion-control systems
- Process monitoring
- Machine diagnostics
- IndraLogic PLC applications
- Industrial operator stations
- Legacy Rexroth control-system maintenance
🔌 Installation Considerations
Before installing R911323940-123, compare the complete part number and physical configuration with the original unit.
Check the display configuration, mounting arrangement, rear connections, power supply, communication interfaces, storage devices, and installed software environment. If the unit is replacing an existing VPP21, document the original wiring and configuration before removal.
The VPP21 connector panel is located on the rear side of the unit, with access provided through the rear housing arrangement.
🛠️ Maintenance & Troubleshooting
If the display unit fails to start or communicate with the machine:
- Verify the incoming power supply.
- Check the rear-side connectors and cable connections.
- Inspect the display for abnormal indications or physical damage.
- Check communication connections between the VPP21 and machine-control system.
- Verify the installed operating environment and application software.
- Check storage media and boot configuration where applicable.
- Confirm that the replacement unit matches the original hardware configuration.
- Review system diagnostic indications before replacing additional components.
For legacy machines, it is recommended to preserve the original VPP21 configuration and software environment before performing hardware replacement.
❓ Common Questions & Answers
Q: What is the Rexroth IndraLogic VPP21 R911323940-123?
A: It is an industrial operating and display unit from the Bosch Rexroth IndraControl VPP21 family.
Q: What size display does the VPP21 use?
A: The VPP21 family is equipped with a 14-inch TFT display.
Q: Is the VPP21 only an HMI display?
A: No. The IndraLogic VPP21 architecture can combine visualization functions with PC-based PLC control applications.
Q: Is R911323940-123 a complete VPP21 unit?
A: The part number identifies a specific VPP21 configuration. The exact hardware contents and options should be verified against the nameplate and original installation.
Q: Does every VPP21 have a touchscreen?
A: No. The VPP21 family includes different operator-interface configurations, including keypad and touchscreen variants.
Q: Can R911323940-123 replace another VPP21?
A: Replacement should be based on the complete part number and hardware configuration rather than the VPP21 family name alone.
Q: What should be checked before purchasing?
A: Verify the complete R911 part number, display/operator configuration, rear connectors, software environment, mounting arrangement, and actual physical condition.
Q: Is this suitable for legacy machine maintenance?
A: Yes. It can be useful as a replacement or spare for existing Rexroth VPP21 installations when the configuration is properly matched.

📌 Replacement Note
For a direct replacement, the complete designation R911323940-123 should be checked against the existing Rexroth VPP21 installation. Because VPP21 units can have different operator-interface and hardware configurations, matching only the series name is not sufficient for a critical machine-control replacement.
