Product Description

I. Overview

The XYCOM XVME-957 is an industrial-grade VMEbus standard PMC (PCI Mezzanine Card) carrier module, with its core positioning as a "VMEbus system function expansion hub - multi-type module bearing interface - equipment interconnection adaptation unit". Its core function is to provide standardized slots and signal conversion channels in the VMEbus architecture, carry expansion modules such as PMC and PC/104, realize efficient data exchange between VMEbus signals and expansion modules, and provide stable power supply for external modules.

As a classic expansion component in industrial control and military systems, this module has core advantages of "high-compatibility expansion - harsh environment adaptation - system collaborative stability": it complies with the VMEbus standard and can seamlessly connect to processor modules such as XVME-653 and XVME-689; it supports multi-type function expansion including I/O, FPGA, Ethernet, and SCSI to meet the needs of different scenarios; its industrial-grade hardware design can withstand high and low temperatures, vibration, and electromagnetic interference. It is widely used in fields such as industrial automation, military equipment, and radar systems, and is a key component for building flexible and scalable VMEbus control systems.

III. Functional Features

1. Multi-Type Module Expansion for Flexible Adaptation to Scenario Needs

The core advantage of the XVME-957 lies in providing standardized expansion interfaces, solving the pain points of "single function and difficult upgrade" of VMEbus systems. In industrial control scenarios, when used with the XVME-653 Pentium processor module, it can connect to an Ethernet module through the PMC slot to realize TCP/IP communication, and at the same time expand a multi-channel I/O module through the PC/104 slot to achieve the dual functions of equipment status collection and control signal output. In military radar systems, it can carry FPGA processing modules for high-speed signal operation, and at the same time connect to SCSI storage modules for real-time data backup, enabling function upgrades without replacing the main controller.

2. Tolerance to Harsh Environments to Ensure Stable System Operation

The module adopts a full industrial-grade hardware design, adapting to the long-term operation needs under extreme working conditions. Its wide-temperature design can cover the environment of outdoor control cabinets in northern winters (-30°C) and machine rooms in southern summers (65°C), and some models can even withstand extreme temperatures of -40°C~85°C; the passed anti-vibration test enables it to operate stably in mobile equipment such as ships and armored vehicles, avoiding signal interruption caused by mechanical bumps. In the strong electromagnetic environment of the power industry, the electromagnetic shielding design of the module can resist interference generated by frequency converters, ensuring that the data transmission accuracy between VMEbus and expansion modules is ≥99.9%.

3. Standardized Bus Compatibility to Simplify System Integration

To meet the demand for "multi-brand equipment interconnection" in industrial control systems, the module strictly follows the VMEbus standard and can be seamlessly integrated into VMEbus backplane architectures of different manufacturers. In automated production lines, it can work in collaboration with Allen-Bradley I/O modules and Siemens communication cards, realizing data interaction between cross-brand equipment through the expanded Modbus Plus module; when used with XYCOM series processor modules, it can realize plug-and-play without additional drivers, greatly shortening the system integration cycle and reducing debugging costs.

4. Collaborative Redundancy Design to Improve System Reliability

The module supports linkage with processor modules of redundant architecture to build a high-reliability control system. In the nuclear power DCS system, when the main XVME-689 processor module fails, the standby processor can seamlessly take over the expansion module through the signal channel of the XVME-976, with a switching time ≤100ms, avoiding control interruption. At the same time, the module provides overcurrent protection for expansion modules; when the external PMC module is short-circuited, it can quickly cut off the power supply and trigger an alarm to prevent the fault from spreading to the main control system.

IV. Operation, Maintenance and Troubleshooting

Daily Maintenance Points

Status Check: Check the communication status of the module through the VMEbus system monitoring software every week to confirm that the expansion modules are online and there is no packet loss in data transmission; check the heat dissipation of the module to ensure that the surface temperature is<65°C.
Connection Inspection: Check the slot connection between the expansion module and the XVME-957 every month to ensure there is no looseness or oxidation; verify the backplane power supply voltage to ensure that the voltage supplied to the expansion module meets the specification requirements.
Compatibility Verification: Before replacing the expansion module, confirm that the module model matches the slot type of the XVME-957 (e.g., PMC modules must comply with the PCI Mezzanine standard) to avoid hardware conflicts.
