Product Introduction
When your industrial VME64 standard control system needs a highly reliable real-time embedded computing unit to execute high-speed real-time control logic and realize seamless data interaction with VME I/O devices, this module acts as the core real-time control brain.
It is a flagship industrial-grade double-high VME single board computer from Motorola MVME162 series, specially designed for heavy-duty industrial real-time control scenarios. It is equipped with a 25MHz MC68LC040 microprocessor, with 4MB parity-protected DRAM and 512KB battery-backed SRAM, which can stably run real-time operating systems such as VxWorks and embedded Linux. It fully complies with VME64 standard, supporting A16/A24/A32 addressing and D8/D16/D32 data widths, and is natively compatible with all standard VME bus I/O modules. It integrates two EIA-232-D serial ports, and optional DMA SCSI bus interface and Ethernet transceiver interface, which can seamlessly connect with industrial storage devices, legacy serial devices and upper DCS platforms. It supports two IndustryPack expansion ports, which can flexibly add A/D conversion, special communication and other functional modules. Its ruggedized reinforced design fully adapts to harsh high-vibration industrial environments, making it a core replacement part for large industrial VME control system maintenance and retrofit projects.

Field Application & Technical Pitfalls
Critical Industrial Scenarios
- **Large Thermal Power Plant Gas/Steam Turbine VME Control System: Acts as the core real-time computing unit for Motorola VME turbine control systems in thermal power plants, realizing high-speed execution of turbine real-time control logic, ensuring the stable operation of large power generation unit control systems.
- **Large Petrochemical Plant Turbine-Driven Compressor VME Control System: Delivers reliable high-performance real-time computing performance for petrochemical production line turbine-driven compressor control systems, adapting to long-term high-temperature operation industrial environments, meeting the zero-misoperation real-time control requirements of large rotating machinery.
- **Large Industrial Automation Production Line VME Distributed Control System: Adapts to high-vibration and high-electromagnetic-interference industrial workshop environments, providing stable high-speed real-time logic processing support for the VME distributed control system of automated production lines.
Non-Negotiable Technical Pitfalls
- ⚠️ Bold Warning 1: Never arbitrarily connect the power input to a voltage that exceeds the +5V/±12V maximum tolerance. The third power channel will experience overvoltage that causes the internal processor circuit to burn out.
- ⚠️ Bold Warning 2: Skipping the pre-commissioning full VME bus addressing and data transmission test will leave you with hidden real-time logic processing delay risks. This module must confirm the full VME64 bus communication performance fully meets industrial control specifications before putting into operation.
- ⚠️ Bold Warning 3: Do not arbitrarily use non-matching non-VME64 standard backplane slots for installation. The third system bus will experience signal deviation that causes the VME I/O data refresh to be abnormal.
A large thermal power plant maintenance team once swapped a MOTOROLA MVME162-213 module and skipped the full bus test. The hidden VME addressing configuration error caused the turbine control logic to respond with delay, resulting in a 1.5-hour partial safety shutdown of the power generation unit.
Quality Control (QC) SOP & Transparency
- Inbound Verification: Cross-check the OEM serial number against Motorola’s official MVME162 part registry, confirm the part number MVME162-213 matches the factory label, and inspect no bent pins or corrosion on all VME backplane and communication connectors.
- Live Rig Testing: Power the unit in a calibrated system test bench, simulate full real-time control logic continuous operation scenarios, and confirm full 2-hour continuous stable operation.
- Parameter Testing: Verify the 25MHz processor logic execution performance meets factory specifications, confirm the bus addressing and data transmission performance meets industrial real-time control standards, and validate all status LED indicators and battery-backed clock functions work properly.
- Final QA & Packaging: Seal the tested module in a static-shielding anti-static bag, attach a unique QC passed serial label, and nest it in foam padding inside a rigid industrial shipping carton.
Frequently Asked Questions (FAQ)
- Can I hot-swap this module while the VME control system is running? No. You must first confirm that the redundant VME control channel is operating normally and the system is in a safe state, then perform the replacement operation after cutting off the module power, otherwise you will trigger unexpected real-time logic interruption risks.
- What exact systems is this module compatible with? It works natively with all standard industrial control systems, and can stably run real-time operating systems such as VxWorks and embedded Linux, but cannot be directly used in non-VME bus systems without custom adaptation.
- How long is the standard warranty for this new surplus unit? 12 months from delivery. It covers all manufacturing defects, but does not extend to units damaged by miswiring, overvoltage input, or improper VME bus configuration in the field.
- How do I tell a genuine OEM unit apart from a refurbished clone? Genuine MOTOROLA MVME162-213 modules have a laser-etched part number on the PCB, not a printed sticker. Clone units almost always fail the full 2-hour continuous VME bus data transmission stability test.
- What is the typical lead time for shipment? In-stock units ship within 48 hours. If you require official Motorola factory real-time control performance test documentation, add 2 extra business days to the turnaround window.
- Can this module replace the older Motorola legacy series VME controller unit? Well, technically it fits the same standard double-high VME rack slot footprint, but you must confirm the VME system firmware version fully supports the module before replacement to ensure 100% system compatibility.
