Motorola MVME-2700-761-I/O

Product Introduction

The Motorola MVME-2700-761-I/O is a highly integrated industrial VMEbus module that combines processing power and versatile I/O capabilities, designed for mid-tier industrial automation systems requiring both real-time control and seamless device connectivity. As a flagship model in the Motorola MVME 2700 series, Motorola MVME-2700-761-I/O bridges the gap between standalone controllers and dedicated I/O modules, eliminating the need for separate processing and interface cards to reduce system complexity.

In automation architectures, Motorola MVME-2700-761-I/O acts as a “central I/O hub with embedded processing”: it executes control logic via its PowerPC 750 processor, collects data from sensors (via expansion modules), and communicates with storage devices (e.g., SCSI hard drives) and operator interfaces (keyboard/mouse) directly. This integration makes Motorola MVME-2700-761-I/O ideal for applications where space is limited—such as manufacturing control cabinets or mobile test systems—while ensuring reliable performance in harsh industrial environments.

Core Advantages and Technical Highlights

Integrated Processing + I/O Design: Unlike discrete controller-I/O combinations, Motorola MVME-2700-761-I/O integrates a 300 MHz PowerPC 750 processor with SCSI, keyboard/mouse, and disk drive interfaces in one 6U module. This reduces VMEbus slot usage by 50% (vs. two separate cards) and eliminates data latency between controller and I/O. For example, in an automotive assembly line, Motorola MVME-2700-761-I/O can process sensor data (e.g., part alignment) and write production logs to a SCSI hard drive simultaneously, with sub-10 ms latency—critical for maintaining 60+ units/hour production rates.

ECC DRAM for Data Integrity: Motorola MVME-2700-761-I/O supports 16 MB–256 MB ECC DRAM, which detects and corrects single-bit errors and alerts on multi-bit errors. This is essential for data-sensitive applications like power grid monitoring, where corrupted sensor data (e.g., voltage readings) could lead to incorrect control decisions. Unlike non-ECC memory in basic modules, ECC DRAM ensures Motorola MVME-2700-761-I/O retains data accuracy even in high-electromagnetic-interference (EMI) environments, such as near large motors or transformers.

Flexible SCSI Storage Integration: The module’s SCSI-2 interface (with resettable terminator power) supports a wide range of industrial storage devices—from 1.44 MB floppy drives (for firmware updates) to 100 GB SCSI hard drives (for long-term data logging). This flexibility makes Motorola MVME-2700-761-I/O adaptable to legacy and semi-modern systems. For instance, a water treatment plant can use Motorola MVME-2700-761-I/O to log hourly pH/turbidity data to a SCSI hard drive (retained for 2 years) while using a floppy drive to load seasonal calibration files—no need for expensive storage upgrades.

Typical Application Scenarios

In large-scale food and beverage manufacturing, Motorola MVME-2700-761-I/O controls a 10-station bottling line. It connects to 20 proximity sensors (via VMEbus I/O expansion) to track bottle position, uses its PowerPC 750 processor to adjust conveyor speed (maintaining 1,200 bottles/hour), and writes production data (e.g., fill volume, reject count) to a 40 GB SCSI hard drive. Operators use the keyboard/mouse interface to access real-time dashboards (via a connected HMI), while the ECC DRAM ensures no data loss during EMI spikes from nearby compressors. Motorola MVME-2700-761-I/O’s 0°C–60°C operating range also withstands the plant’s temperature fluctuations, ensuring 99.8% uptime.

For mobile industrial test systems (e.g., aerospace component vibration testing), Motorola MVME-2700-761-I/O serves as the core controller. Mounted in a compact 6U chassis, it processes data from 8 accelerometers (via a PMC analog card), logs test profiles to a 256 MB ECC DRAM buffer, and saves final results to a SCSI tape drive (for archive). The module’s hot-swap capability allows technicians to replace the tape drive mid-test without shutting down the system, while its vibration resistance (1.5 g rms) ensures stable operation during testing. Motorola MVME-2700-761-I/O’s all-in-one design reduces the test system’s size by 30% compared to multi-module setups.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME-2700-761-I/O, verify the VMEbus chassis supports 6U modules and provides 85–264 VAC input (use a multimeter to confirm voltage tolerance ±5%). Gather tools: anti-static wristband (to protect the PowerPC 750 processor), torque screwdriver (0.5 N·m for chassis mounting), SCSI cable tester, and a laptop (for firmware configuration). Ensure the chassis is grounded to avoid EMI interference—critical for SCSI and ECC DRAM performance. If adding a RAM 200 mezzanine, install it first: align with the module’s mezzanine slot, press gently until seated, and secure with 2×M3 screws.

Maintenance suggestions: For daily upkeep, check Motorola MVME-2700-761-I/O’s voltage LED—steady green indicates normal operation; flickering means a voltage issue (inspect SCSI devices and power supply). Clean the module’s air vents monthly with compressed air (30 PSI max) to prevent overheating. Every 6 months, back up Flash ROM/ECC DRAM data to a secure server and test the SCSI interface by connecting a known-good drive. If Motorola MVME-2700-761-I/O shows SCSI errors, replace the cable (use shielded SCSI-2 cables) and reset the polyswitch (power cycle the module). Store spare modules in anti-static bags (15°C–25°C, 40%–60% humidity) to preserve ECC DRAM and Flash memory.
