Description
Product Introduction
The Bosch Rexroth VEP40.3CEN-256NN-MAD-128-NN-FW is an IndraControl VEP 40 embedded PC and operator interface designed for industrial visualization and machine-operation applications. Bosch Rexroth’s own documentation identifies this exact type code as R911170850 and describes it within the VEP 40 embedded-PC family. The unit combines a 12.1-inch TFT touchscreen with an embedded computing platform, allowing the operator interface and application runtime to be installed directly in the machine control cabinet or operator station.
The VEP40.3CEN-256NN-MAD-128-NN-FW uses an 800 × 600 SVGA display and a 600 MHz Celeron M processor. Published documentation identifies 256 MB of application memory and 128 MB of flash storage, together with two CompactFlash slots. Interfaces include one RS-232 port and two USB 2.0 ports. The unit accepts a 19–30 VDC supply and has an IP65-rated front panel, making it appropriate for embedded machine-panel installation rather than general office-computing use.
From a maintenance perspective, R911170850 should be treated as part of the complete identification. The VEP40 platform contains multiple hardware configurations that can look similar externally while differing in processor, memory, display, storage, and operating-system configuration. A replacement should therefore be matched by the complete type code rather than simply by the VEP40 family name. Bosch Rexroth’s documentation specifically associates the requested type code with R911170850.

Application Scenarios & Engineering Considerations
The is intended primarily for machine-level visualization and operator interaction.
- Machine HMI: Provides touchscreen visualization for machine status, parameters, alarms, and operator commands.
- Industrial control panels: The embedded format allows the computer and display to be integrated into a machine enclosure.
- Legacy Rexroth systems: Particularly relevant when maintaining older IndraControl installations where the original Windows CE environment must be preserved.
- Service and diagnostic stations: The serial and USB interfaces provide access for configuration, maintenance, and peripheral devices.
- Embedded visualization: The PC-based architecture provides more computing capability than a simple terminal while retaining a dedicated industrial-panel form factor.
Field note: This is a legacy Windows CE platform. For an existing machine, compatibility with the original HMI application is generally more important than simply matching display size or connector locations.

The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not substitute by display size alone.
A 12.1-inch does not automatically mean it is electrically or software-compatible with another 12.1-inch .
How to avoid it: Match NN- / R911170850 against the machine documentation and existing nameplate.
⚠️ Verify the operating-system/application environment.
The published specifications identify Windows CE 4.2.
A replacement with a different Windows CE version or a different Rexroth software image can behave differently even when the hardware appears compatible.
⚠️ Do not confuse 256 MB application memory with 128 MB flash.
The type code contains separate memory-related designations. Published documentation identifies 256 MB application memory and 128 MB flash.
⚠️ Check the CompactFlash configuration.
The unit has two CF sockets, and the machine’s boot/application arrangement may depend on the original storage configuration.
How to avoid it: Back up the original CF media before removing a functioning unit whenever site procedures permit.
⚠️ Verify power and enclosure conditions.
The specified input range is 19–30 VDC, while the unit’s input power can reach approximately 53 W. The front is IP65, but the overall unit is not IP65; the rear is specified as IP20.
