Motorola MVME-167-01B

Product Introduction

The Motorola MVME-167-01B is an industrial VMEbus single-board computer (SBC) from Motorola, now part of Emerson’s product line. It features a 25 MHz Motorola MC68040 processor and 4 MB of memory. Designed for industrial use, it has a SCSI storage interface and an Ethernet port for communication. With its VMEbus compatibility in a 3U form factor, it can be easily integrated into existing VMEbus-based industrial systems. This SBC is suitable for applications where reliable, mid-level computing power is required in an industrial setting, such as in basic industrial control systems, data acquisition tasks in small to medium-sized industrial processes, or as a component in legacy industrial automation architectures that still rely on the VMEbus standard.

Core Advantages and Technical Highlights

Proven Processor Performance: The Motorola MC68040 processor in the MVME-167-01B was a well-regarded chip during its era. With a 25 MHz clock speed, it offers reliable computing power for industrial applications of its time. It can handle tasks such as basic data processing from multiple sensors in a small manufacturing line, like processing data from 10 – 20 proximity sensors to control the movement of conveyor belts. The processor’s 32-bit architecture allows for efficient handling of industrial data types and operations, enabling seamless integration with other industrial components in a VMEbus system.

SCSI Storage Connectivity: The inclusion of a SCSI interface provides a reliable and fast storage connection option. In industrial scenarios, this can be used to attach SCSI hard drives for storing critical process data. For example, in a food processing plant, the SBC can use the SCSI drive to log production data, such as batch numbers, processing times, and quality control parameters. The SCSI interface’s ability to support multiple devices also means that additional storage expansion can be achieved if needed, enhancing the data storage capabilities of the system.

VMEbus Compatibility: As a VMEbus-based SBC, the MVME-167-01B benefits from the widespread use and reliability of the VMEbus standard. It can be easily integrated into existing VMEbus chassis and systems. This compatibility allows for the use of a wide range of VMEbus-compatible I/O modules. For instance, it can be paired with VMEbus analog I/O modules to monitor and control process variables like temperature and pressure in a chemical manufacturing plant. The VMEbus also enables efficient communication between the SBC and other VMEbus-based components, ensuring smooth operation within an industrial automation setup.

Basic Diagnostic Tools: The MVME-167-01B likely comes with basic diagnostic features. Built-in self-test functionality for the processor and memory helps in quickly identifying hardware issues during startup. LED indicators for power status and basic system health provide visual cues to operators. In a factory environment, if the power LED is not lit, it immediately signals a power supply issue, while a malfunctioning memory self-test might be indicated by a specific pattern of diagnostic LED lights. This helps in minimizing downtime by allowing for quick identification and resolution of problems.

Typical Application Scenarios

Small Manufacturing Lines: In a small automotive parts manufacturing line, the Motorola MVME-167-01B can be used to control the production process. It can connect to multiple sensors, such as limit switches on robotic arms and pressure sensors on stamping machines, through VMEbus I/O modules. The SBC processes the sensor data to ensure that the production line operates smoothly. For example, if a limit switch indicates that a robotic arm has reached its end position, the SBC can send a signal to the next machine in the line to start its operation. The SCSI storage can be used to log production data, including the number of parts produced, any errors that occurred, and the cycle times of each machine.

Industrial Data Acquisition: In a power generation plant, the MVME-167-01B can be employed for data acquisition. It can connect to various sensors measuring parameters such as temperature, pressure, and vibration of generators and turbines. Using its Ethernet port, it can transmit the collected data to a central monitoring system for further analysis. The SBC’s ability to handle multiple data streams from different sensors simultaneously makes it suitable for this application. The data logged on the SCSI drive can be used for historical analysis, helping in predicting equipment failures and scheduling maintenance.

Legacy Industrial Automation Upgrades: For companies with existing legacy industrial automation systems based on the VMEbus standard, the MVME-167-01B can be a cost-effective option for upgrades. For example, in a textile mill with an old VMEbus-based control system, replacing a malfunctioning SBC with the MVME-167-01B can restore system functionality. It can be easily integrated into the existing VMEbus backplane and can communicate with the same I/O modules as the previous SBC. This allows the mill to continue using its existing infrastructure while getting the benefits of a new SBC, such as improved diagnostic capabilities and better processor performance for handling the textile production control tasks.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing the Motorola MVME-167-01B, ensure that the VMEbus chassis is compatible with 3U modules and provides the appropriate power supply (check for correct voltage levels and stability, as deviations can cause damage to the SBC). Gather necessary tools such as an anti-static wristband to protect the sensitive components during handling, a screwdriver for chassis mounting, and an Ethernet cable tester if required to verify network connectivity. Inspect the VMEbus backplane connector for any signs of damage or corrosion and clean it if necessary. If planning to use additional expansion modules, ensure their compatibility with the MVME-167-01B and the VMEbus system.

Maintenance suggestions: Regularly check the LED indicators on the MVME-167-01B to monitor its operational status. A steady power LED indicates proper power supply, while other LEDs may indicate system health, network connectivity, or diagnostic results. Periodically clean the SBC to remove dust, as dust accumulation can lead to overheating and affect performance. In industrial environments, dust can build up quickly, so cleaning every few months is advisable. If possible, perform regular software updates and patches for the operating system and any installed applications to ensure optimal performance and security. Keep a record of any diagnostic error messages or unusual behavior for troubleshooting purposes.

Commissioning process: After installation, power on the system and perform basic system checks. Check for proper initialization of the processor, memory, and communication interfaces. Use diagnostic tools, if available, to test the functionality of the SBC. Configure the Ethernet settings to enable network communication with other devices in the industrial network. Connect and test any attached storage devices, such as SCSI hard drives, to ensure data can be stored and retrieved correctly. If using expansion modules, verify their functionality by testing the relevant I/O operations. For example, if an analog I/O module is installed, connect it to a known analog sensor and check if the SBC can accurately read the sensor data.
