EMERSON MVME6100 PMCSPAN MV6100COMI

Description

Product Description

The EMERSON MVME6100, often associated with the designation PMCSPAN MV6100COMI, is a high-performance, single-board computer (SBC) module designed for embedded industrial computing and control applications. Based on the VMEbus architecture, this module serves as a powerful processor platform within systems like Emerson’s (formerly GE’s) Ovation DCS or other industrial automation and military/aerospace systems. The EMERSON MVME6100 integrates a robust microprocessor, memory, and various I/O interfaces onto a single board, functioning as a critical node for data acquisition, processing, or control logic execution. For detailed technical specifications, user manuals, and compatibility guides, the primary resource is the official Emerson Automation Solutions documentation portal for the EMERSON MVME6100. As a core computing element, the reliable operation of the MVME6100 is vital for the deterministic performance required in real-time control and monitoring systems. Its design caters to applications demanding significant processing power in a harsh, industrial-grade form factor.

Product Parameters

• Manufacturer / Brand: Emerson (formerly Motorola Computer Group, then Emerson Network Power).
• Series: MVME6100 Series Single Board Computer.
• Model: MVME6100 (with variant PMCSPAN MV6100COMI likely indicating a specific configuration with PMC (PCI Mezzanine Card) and communication options).
• Processor: Historically features a high-performance PowerPC or Intel architecture microprocessor (e.g., PowerPC 750FX, Intel Core Duo, depending on the specific variant and generation).
• Memory: Equipped with substantial onboard SDRAM and flash memory for the operating system and application software.
• Bus Interface: Primary interface is the VME64 (VITA 1.1) bus for integration into a VME backplane chassis.
• Expansion: Includes one or more PMC (PCI Mezzanine Card) sites for adding specialized I/O functions such as additional serial ports, Ethernet, or fieldbus controllers.
• Onboard I/O: Typically includes dual Ethernet ports (10/100/1000 Mbps), serial ports (RS-232/422/485), USB ports, and graphics capability.
• Operating System Support: Designed to run real-time operating systems (RTOS) such as VxWorks, Linux, or proprietary RTOS for control applications.
• Form Factor: 6U VME format card designed for installation in a VME subrack or chassis.
• Power Supply: Powered from the VME backplane (+5V, +/-12V).

Advantages and Features

• High Computational Power: Provides substantial processing capability for complex control algorithms, data handling, and networking tasks within an industrial control chassis.
• Modular Flexibility: The PMC expansion sites allow customization of I/O capabilities to meet specific application needs without redesigning the core CPU board.
• Robust Industrial Design: Built to withstand the temperature, vibration, and electrical noise of industrial environments, unlike commercial-grade computing boards.
• Deterministic Performance: When paired with a real-time operating system, it can deliver predictable and reliable response times, which is critical for control applications.
• Proven VME Ecosystem: Leverages the long-established, reliable VMEbus standard for high-performance and mission-critical embedded systems.

Application Cases in Industry

• Distributed Control System (DCS) Controller: In an Emerson Ovation DCS, the EMERSON MVME6100 can serve as a powerful process controller or a data acquisition server within a VME chassis.
• Military/Aerospace Test & Simulation: Used in ground-based test stands for aircraft components or in simulator systems where real-time processing of complex models is required.
• Industrial Data Gateway: Acts as a high-performance communication gateway, aggregating data from multiple fieldbus networks (via PMC cards) and bridging it to an enterprise network.
• Telecommunications Infrastructure: Employed in critical telecom switching or monitoring equipment that requires a robust, reliable computing platform.
• Scientific Research Equipment: Provides the processing core for data-intensive instruments in laboratory or field settings.

Comparison with Competing Products

Competing products are other high-performance 6U VME SBCs from manufacturers like Curtiss-Wright (formerly Dy-4/SBS) or Congatec. The EMERSON MVME6100 differentiates itself through its strong heritage in the industrial automation sector, particularly within Emerson’s own Ovation ecosystem. Compared to a standard industrial PC, the MVME6100 offers superior ruggedness, a modular expansion path via PMC, and seamless integration into a VME backplane with other specialized I/O cards. Its primary competition now comes from more modern form factors like VPX or compactPCI Serial, but the MVME6100 remains a workhorse in legacy and long-lifecycle systems.

Selection Suggestions and Precautions

• Selection Suggestions:
  1. Select the EMERSON MVME6100 primarily as a replacement board in an existing VME-based system (e.g., an Ovation controller) or when designing a new system that requires a proven, rugged VME computing platform.
  2. Carefully verify the exact processor type, memory size, and PMC configuration (PMCSPAN MV6100COMI) to match the performance requirements and software compatibility of your application.
  3. Ensure compatibility with the VME chassis, backplane revision, and the system’s operating system/software drivers.
• Precautions:
  1. Firmware and Software Compatibility: The board’s BIOS/firmware version and available drivers for the target operating system are critical. Mismatches can prevent the system from booting or cause instability.
  2. Thermal Management: High-performance processors generate significant heat. Ensure the VME chassis has adequate forced airflow or conduction cooling specifically designed for the MVME6100‘s thermal profile.
  3. ESD and Handling: The board is highly sensitive to electrostatic discharge. Handle with proper ESD precautions—use a grounded wrist strap and an anti-static bag.
  4. PMC Card Selection: If using PMC expansion cards, ensure they are compatible with the specific MVME6100 variant, are supported by the operating system, and do not exceed the power budget of the PMC site.
  5. Obsolescence and Support: As a mature product, long-term availability may be a concern. Source from authorized Emerson distributors or reputable specialty suppliers. Verify the availability of technical documentation and potential firmware updates. When integrating, pay close attention to the VME slot addressing and interrupt settings as configured in the system.
