Motorola MVME31006E-1152 Replacement for MVME3100

Product Overview

Motorola MVME31006E-1152 Replacement for MVME3100: Seamless Transition & Legacy System Upgrade

The Motorola MVME31006E-1152 is a high-performance VMEbus Single-Board Computer (SBC) from the MVME3100 series, built around the Freescale MPC8540 PowerPC processor. For facilities running legacy VMEbus-based control architectures — including distributed control systems (DCS), SCADA platforms, and real-time embedded control cabinets — this module represents a proven, drop-in compatible replacement for discontinued or end-of-life MVME3100-series boards. TOPNLMS maintains verified stock of the MVME31006E-1152 to support your migration, retrofit, or emergency replacement requirements with minimal disruption to production.

Whether your plant is transitioning from an older MVME2700 or MVME5500 single-board computer, or you are replacing a failed MVME31006E-1152 in an existing rack, this module integrates directly into standard 6U VMEbus backplanes without requiring chassis modifications. The onboard 1 GHz PowerPC core, 512 MB DDR SDRAM, and dual Gigabit Ethernet ports ensure backward compatibility with existing VxWorks, LynxOS, or Linux-based real-time operating environments. Field engineers report that existing BSP (Board Support Package) configurations require minimal adjustment when migrating from earlier MVME3100 sub-variants.

Seamless Upgrade Solutions

A successful migration to the MVME31006E-1152 rarely involves the SBC alone. In most VMEbus control cabinet retrofits, the surrounding ecosystem of modules must be evaluated for compatibility and, where necessary, upgraded in parallel. During the transition from legacy MVME5500 or MVME2700 platforms, engineers commonly address the VMEbus backplane and chassis first — ensuring the existing 6U VMEbus chassis and its power distribution rails are rated for the MVME3100’s power profile. In many installations, the MVME712M transition module or equivalent rear-transition module (RTM) is retained, as its I/O connector mapping aligns with the MVME31006E-1152’s P2 connector pinout.

For systems that rely on synchronous serial communication or legacy fieldbus protocols, the MVME31006E-1152 is frequently deployed alongside VMEbus communication modules such as the MVME2502 or third-party PMC (PCI Mezzanine Card) adapters that support PROFIBUS DP, CANopen, or DeviceNet. Where the legacy system used a dedicated MVME761 or MVME712 I/O transition board for analog and digital I/O routing, these can typically be retained without rewiring, as the P2 connector standard is preserved across the MVME3100 family.

Power integrity is a critical consideration in any VMEbus retrofit. If the existing VMEbus chassis power supply — such as a Motorola MVME55006E or equivalent third-party 6U VMEbus PSU — is aging or undersized for the updated board’s power draw, replacement with a modern, higher-efficiency VMEbus power supply is recommended before commissioning the MVME31006E-1152. Similarly, where the control cabinet includes a Motorola MVME162 or MVME167 as a secondary processor or I/O controller, these can continue to coexist on the same VMEbus backplane without conflict, provided slot addressing and interrupt vectors are correctly configured in the BSP.

For programming and commissioning, a compatible serial programming cable (DB9 to RJ45 or USB-to-serial adapter) is required to access the board’s console port during initial boot and BSP configuration. Engineers migrating from VxWorks 5.x to VxWorks 6.x environments should verify that their existing Wind River Workbench toolchain supports the MPC8540 target BSP. In installations where a Motorola MVME3100 series board previously served as the VMEbus system controller, the MVME31006E-1152 assumes the same system controller role with no additional configuration required.

Retrofit Guidance FAQ

Q: Can the MVME31006E-1152 replace my existing MVME3100 variant without rewiring?
A: Yes. The MVME31006E-1152 uses the standard 6U VMEbus P1/P2 connector layout. In most cases, existing backplane wiring, rear-transition modules, and I/O cabling can be retained without modification. Verify that your RTM’s P2 pinout matches the MVME3100 standard before installation.

Q: Is the MVME31006E-1152 compatible with my existing VxWorks image?
A: Compatibility depends on your BSP version. VxWorks 6.x BSPs compiled for the MPC8540 target are directly compatible. VxWorks 5.x images will require recompilation against the MVME3100 BSP. Wind River provides migration guides for this transition.

Q: What communication protocols does this board support?
A: The MVME31006E-1152 natively supports VMEbus (VME64/VME64x), dual Gigabit Ethernet (TCP/IP, UDP, Modbus TCP), and dual UART serial (RS-232). Fieldbus protocols such as PROFIBUS, CANopen, or DeviceNet require a compatible PMC or XMC mezzanine card installed in the board’s PMC slot.

Q: Will this board fit in my existing 6U VMEbus chassis?
A: Yes. The MVME31006E-1152 is a standard 6U VMEbus form factor board and fits any compliant 6U VMEbus chassis without mechanical modification. Ensure the chassis power supply provides adequate +5V and ±12V current capacity per the MVME3100 hardware reference manual.

Q: How do I handle the transition from a MVME5500 or MVME2700 to this board?
A: The primary differences are processor architecture (G4 PowerPC vs. MPC8540 e500 core) and memory addressing. A BSP migration is required, and existing application software compiled for the G4 target must be recompiled for the e500 core. TOPNLMS can provide technical documentation to support your engineering team during this transition.

Q: What is the physical installation space requirement?
A: The board occupies a single 6U VMEbus slot (233.35 mm × 160 mm). No adjacent slot clearance is required unless a PMC mezzanine card is installed, in which case one adjacent slot must remain free for airflow.

Warranty Assurance

Every MVME31006E-1152 unit shipped by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a multi-point functional inspection including power-on self-test (POST) verification, Ethernet port continuity check, memory integrity test, and VMEbus interface validation. Units that do not pass inspection are not shipped.

In the event of a confirmed defect within the warranty period, TOPNLMS will arrange a replacement unit or issue a full refund, subject to return inspection. Our average response time for warranty claims is within 2 business days. Replacement units are dispatched from our Xiamen warehouse with priority shipping to minimize your system downtime.

For procurement teams requiring documentation, TOPNLMS provides a certificate of conformance, packing list, and shipment tracking for every order. We support T/T bank transfer, PayPal, and trade assurance payment terms. Bulk orders and long-term supply agreements are available for MRO and OEM customers.
