Motorola MVME-166-11A

Product Introduction

The Motorola MVME945B-001 is a legacy industrial VMEbus Ethernet communication module designed to integrate legacy MVME-based control systems with modern IP networks—addressing the connectivity gap between VME hardware (like the mid-tier SBC Motorola MVME-166-11A) and Ethernet-enabled devices (e.g., SCADA servers, remote HMIs, cloud monitoring platforms). Unlike serial communication modules such as Motorola MVME334B (limited to RS-232/RS-485), Motorola MVME945B-001 delivers 10/100Base-T Ethernet speeds, enabling high-bandwidth data transfer for real-time monitoring and remote control.

In automation architectures, Motorola MVME945B-001 acts as a “VME-to-Ethernet gateway”: it translates data between the VMEbus (hosted by SBCs like Motorola MVME-166-11A) and IP networks, facilitating tasks such as streaming sensor data from Motorola MVME-177-003 (analog input module) to a central SCADA system or receiving remote control commands for Motorola MVME2101-1 (high-current DO module). Its auto-negotiation feature ensures compatibility with both 10 Mbps and 100 Mbps networks, while built-in diagnostics simplify troubleshooting—making Motorola MVME945B-001 ideal for legacy systems undergoing modernization, such as mid-scale manufacturing plants, regional utility grids, or industrial test facilities.

Core Advantages and Technical Highlights

High-Speed Ethernet Connectivity for Legacy VME Systems: Motorola MVME945B-001’s 10/100Base-T interface delivers up to 100 Mbps data transfer—100x faster than the 1 Mbps max of Motorola MVME334B’s RS-485 ports. This speed is critical for applications like semiconductor manufacturing, where Motorola MVME945B-001 streams real-time process data (from Motorola MVME-166-11A and Motorola MVME-177-003) to a cloud-based analytics platform at 500 samples/second—enabling predictive maintenance and reducing unplanned downtime by 25%. The module’s full-duplex support also eliminates data collisions, ensuring reliable transmission for time-sensitive control signals.

Seamless Integration with Legacy MVME Hardware/Software: Motorola MVME945B-001 is engineered to work natively with MVME series SBCs (e.g., Motorola MVME-166-11A) and operating systems (e.g., VxWorks 5.4+), requiring no custom hardware modifications or extensive software rewrites. A food processing plant upgrading its control system can install Motorola MVME945B-001 into an existing VME chassis alongside Motorola MVME-166-11A and Motorola MVME2101-1, retaining all legacy I/O while adding Ethernet connectivity—avoiding the $50,000+ cost of replacing the entire control system. Its A16/D16 VMEbus interface also ensures plug-and-play compatibility with older MVME modules.

Built-In Diagnostics + Network Flexibility: Motorola MVME945B-001 includes LED indicators for link status, speed, and data activity, plus local/remote loopback tests—simplifying troubleshooting for technicians. For example, if a utility company’s SCADA system loses communication with Motorola MVME-166-11A, technicians can use the module’s loopback test to isolate issues (e.g., faulty cable vs. network configuration). The module’s auto-negotiation and DHCP client support also reduce setup time: it automatically detects network speed (10/100 Mbps) and obtains an IP address, eliminating manual configuration errors that delay system deployment.

Typical Application Scenarios

In mid-scale automotive assembly, Motorola MVME945B-001 is paired with Motorola MVME-166-11A to connect a robotic welding cell to a factory-wide MES (Manufacturing Execution System). The module streams real-time production data (weld count, defect rate, cycle time) from Motorola MVME-166-11A to the MES via 100Base-TX Ethernet, enabling supervisors to monitor throughput remotely. It also receives MES commands to adjust welding parameters (e.g., current, duration), which Motorola MVME-166-11A executes via Motorola MVME2101-1 (controlling weld torches). Motorola MVME945B-001’s 1.5 g vibration resistance withstands robot movements, while IP filtering prevents unauthorized access to the welding cell’s control system—meeting ISO/TS 15066 safety standards.

For regional water utility monitoring, Motorola MVME945B-001 integrates a remote pump station’s Motorola MVME-166-11A SBC with a central SCADA system. The module transmits pump status data (flow rate, pressure, motor temperature—collected via Motorola MVME-177-003) to SCADA via 10Base-T Ethernet (compatible with the utility’s existing network). It also receives SCADA commands to start/stop pumps or adjust speed, which Motorola MVME-166-11A implements via digital output modules. Motorola MVME945B-001’s -10°C–60°C operating range handles outdoor enclosure temperatures, while password-protected configuration prevents tampering—ensuring reliable water supply for 30,000+ households.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing Motorola MVME945B-001, verify the VMEbus chassis has a 3U slot and the host SBC (e.g., Motorola MVME-166-11A) supports A16/D16 addressing. Confirm the power supply provides +5V DC (±5%) and +12V DC (±10%)—use a multimeter to avoid voltage ripple that disrupts network communication. Gather tools: anti-static wristband (protects network controller), torque screwdriver (0.3 N·m for mounting), Ethernet cable tester, and a laptop (for IP configuration). Use Cat5e/Cat6 shielded Ethernet cables (max length 100 m) to connect the module to the network—route separately from power cables (min 15 cm separation) to reduce EMI.

Maintenance suggestions: For daily upkeep, check Motorola MVME945B-001’s LEDs—steady power, green link status, and blinking transmit/receive lights indicate normal operation. Test network connectivity weekly by pinging the module’s IP address from the SCADA system; if unresponsive, run a loopback test to isolate issues (e.g., faulty cable vs. module failure). Clean the module’s vents monthly with compressed air (20 PSI max) to prevent overheating. If security settings need updating, access the serial console (via RS-232) to modify IP filtering or passwords. Store spare Motorola MVME945B-001 units in anti-static bags (15°C–25°C, 40%–60% humidity) to preserve network controller components.
