Product Details

XVME-600 70600-001 Product Description

The Xycom XVME-600 (P/N 70600-001) is a high-performance VMEbus CPU board engineered for demanding industrial control architectures. Designed to serve as the central processing node within VME-based automation platforms, this board delivers deterministic execution, robust I/O coordination, and reliable inter-module communication across multi-layer control systems. Whether deployed in legacy modernization projects or integrated into active production environments, the XVME-600 provides the processing backbone that sustains system-wide coherence across control, I/O, communication, power, HMI, actuation, protection, and maintenance layers.

At NANKMOS, every XVME-600 70600-001 unit undergoes pre-shipment functional verification, ensuring electrical integrity and firmware compatibility before dispatch. Backed by a 12-Month Warranty and supported by a stable global inventory network, this module is available for rapid deployment to manufacturing plants, power substations, petrochemical facilities, water treatment stations, and other process-critical environments.

The XVME-600 70600-001 does not operate in isolation — its true value emerges when positioned within a fully integrated VMEbus automation platform. In a typical multi-layer control architecture, this CPU board functions as the system master, coordinating data flow between subordinate I/O modules, communication gateways, and operator interfaces.

On the I/O layer, the XVME-600 interfaces directly with Xycom XVME-010 analog input modules and XVME-012 digital I/O modules mounted on the same VME backplane. These modules feed real-time field signals — temperature, pressure, flow, and discrete status — into the CPU for scan-cycle processing. The backplane itself, such as the Xycom XVME-400 series VME chassis, provides the electrical and mechanical foundation for multi-slot expansion, allowing engineers to scale I/O capacity without redesigning the control cabinet layout.

On the communication layer, the XVME-600 supports serial communication protocols including RS-232 and RS-422/485, enabling integration with SCADA hosts, remote terminal units (RTUs), and fieldbus-connected devices. In facilities where Profibus DP or Modbus RTU networks are already deployed, a compatible VME communication module — such as the Xycom XVME-530 or equivalent fieldbus gateway card — can be inserted into an adjacent slot to extend protocol reach without replacing the CPU node.

On the power layer, the XVME-600 relies on a regulated VMEbus power supply module — typically a 200W or 300W industrial PSU with active current sharing — to maintain stable +5 VDC and ±12 VDC rails across all installed boards. Power redundancy can be achieved by pairing dual PSU modules within the same chassis, ensuring uninterrupted CPU operation during single-supply failures.

On the HMI layer, the XVME-600 connects to operator workstations or panel PCs running supervisory software via serial or Ethernet links. In legacy installations, Xycom's own industrial panel computers — such as the Xycom 9000 series or compatible third-party HMI terminals — serve as the visualization front-end, displaying process variables and alarm states derived from the CPU's real-time data outputs.

On the protection and redundancy layer, the XVME-600 can be deployed in hot-standby or warm-standby configurations using VME-compatible redundancy controllers. Signal isolators and surge protection modules installed at the I/O terminal level further protect the CPU from field-side transients, extending board service life in electrically noisy environments such as motor control centers, arc furnace control rooms, and high-voltage switchgear panels.

On the maintenance layer, the XVME-600's modular VMEbus architecture simplifies board-level replacement and diagnostic isolation. Maintenance engineers can extract and reinsert individual modules — including the CPU, I/O boards, and communication cards — without disturbing adjacent slots, reducing mean time to repair (MTTR) and minimizing production downtime during scheduled or corrective maintenance cycles.

Manufacturing & Assembly Lines: In automotive and electronics manufacturing, the XVME-600 serves as the central controller for multi-axis motion coordination, conveyor sequencing, and quality inspection systems. Its deterministic scan cycle ensures precise timing across distributed I/O nodes, supporting high-throughput production with minimal cycle-time variance.

Power Generation & Substation Automation: Deployed in thermal power plants and hydroelectric stations, the XVME-600 manages turbine governor control, excitation regulation, and protection relay coordination. Its VMEbus architecture supports integration with IEC 61850-compatible communication modules, enabling substation automation and remote SCADA connectivity.

Petrochemical & Refinery Process Control: In continuous process environments, the XVME-600 handles PID loop execution, batch sequencing, and safety interlock logic. Its robust operating temperature range and industrial-grade construction make it suitable for control rooms adjacent to hazardous process areas, where thermal stability and long-term reliability are non-negotiable.

Water & Wastewater Treatment: Municipal water treatment facilities use the XVME-600 to automate pump station control, chemical dosing sequences, and filtration cycle management. The board's serial communication capability enables integration with remote pump stations via Modbus RTU over RS-485, supporting centralized SCADA monitoring across geographically distributed infrastructure.

Mining, Metallurgy & Heavy Industry: In ore processing plants and steel mills, the XVME-600 controls conveyor drives, crusher sequencing, and furnace temperature regulation. Its compatibility with VME-based I/O expansion modules allows engineers to address large-scale I/O counts — often exceeding several hundred discrete and analog points — within a single rack-mounted control system.

Marine & Offshore Automation: Shipboard automation systems and offshore platform control panels deploy the XVME-600 for engine room monitoring, ballast control, and dynamic positioning support systems. The board's compact VME form factor and wide operating temperature tolerance suit the space-constrained, vibration-prone environments typical of marine installations.

Q1: Is the Xycom XVME-600 70600-001 compatible with existing VMEbus chassis and I/O modules from other manufacturers? The XVME-600 conforms to the IEEE 1014 VMEbus standard, ensuring mechanical and electrical compatibility with standard 6U VME chassis from Xycom and other VMEbus-compliant manufacturers. It can coexist in the same backplane with third-party VME I/O modules, communication cards, and memory boards, provided that bus arbitration and address mapping are correctly configured during system commissioning. NANKMOS recommends verifying slot addressing and interrupt vector assignments before final installation to avoid bus conflicts in mixed-vendor architectures.

Q2: What installation and commissioning steps are required when integrating the XVME-600 into an active control system? Prior to installation, engineers should confirm power supply rail voltages (+5 VDC, ±12 VDC) are within specification under full chassis load. The XVME-600 should be inserted into the system slot (typically slot 1) with the chassis powered down. After mechanical seating and connector engagement, power-on diagnostics — including ROM self-test and memory check — should be observed via the board's status indicators or serial debug port. Firmware version compatibility with existing application software should be verified before transitioning the system to run mode. NANKMOS provides pre-shipment test reports upon request to support commissioning documentation requirements.

Q3: What does the 12-Month Warranty cover, and how does NANKMOS support long-term inventory availability for the XVME-600? NANKMOS's 12-Month Warranty covers manufacturing defects, electrical failures under normal operating conditions, and firmware integrity for the XVME-600 70600-001. In the event of a warranty claim, NANKMOS provides advance replacement or repair services to minimize system downtime. For long-term maintenance planning, NANKMOS maintains a dedicated inventory of XVME-600 units and compatible XVME-series modules, supporting customers with multi-year spare parts programs. Engineers managing aging VMEbus installations can contact NANKMOS to establish blanket purchase agreements or consignment stock arrangements, ensuring critical spare availability without capital-intensive bulk purchasing.
