As an industrial automation expert, the MOTOROLA MVME5101-0131 is a VMEbus Single Board Computer (SBC). This means it’s a complete computer on a single printed circuit board (PCB) designed to plug into a VMEbus chassis.
Motorola (and later Emerson Embedded Computing, which acquired Motorola’s embedded computing division) produced the MVME series as robust, high-performance computing solutions primarily for industrial automation, telecommunications, and military/aerospace applications.
The MVME5101-0131 is part of the MVME5100 series, which features the PowerPC® processor. These boards were known for their powerful processing capabilities and rich communication interfaces, making them suitable for demanding real-time control and data processing tasks.
Key Features and Benefits:
- VMEbus Compatibility: Designed to seamlessly integrate into a VMEbus system. The VMEbus is a widely adopted, high-performance backplane bus standard used in industrial and critical applications due to its ruggedness and real-time capabilities.
- PowerPC Processor: Utilizes a PowerPC® processor (likely an MPC7400 or MPC750), providing significant processing power for complex computations and real-time control algorithms. The MPC7400, in particular, included AltiVec™ technology for algorithmic-intensive computations.
- Onboard Memory: Includes onboard memory (e.g., 64MB RAM as indicated by some sources) to support the operating system and application programs.
- Integrated Communication: Features built-in communication protocols and interfaces, commonly including Ethernet ports (10/100 Mbps) for network connectivity, remote control, and monitoring. It also typically has serial ports for various peripheral connections.
- Industrial Reliability: Built with robust components and design principles suitable for harsh industrial environments, ensuring stability and reliability in demanding conditions.
- Real-time Performance: Optimised for real-time operating systems, crucial for applications requiring deterministic behavior and precise timing.
- Versatile Application: Can be used in various industrial control systems, including DCS (Distributed Control Systems), PLC (Programmable Logic Controller) systems, and general embedded computing applications.
- Legacy System Support: As part of a well-established product line, the MVME5101-0131 is often sought after for maintaining or extending the life of existing industrial systems.
