Vibro-Meter CPUR2 Central Processing and Controller Card

Vibro-Meter CPUR2 Central Processing and Controller Card is a core component of Meggitt's VM600 Machinery Protection System (MPS) and Condition Monitoring System (CMS).

Installed directly into the central slot of 19-inch VM600 racks (such as ABE04x), the CPUR2 module manages internal rack communications, processes system parameters, and bridges vibration protection hardware to high-level plant networks (DCS, SCADA, and VibroSight condition monitoring software).

Product Introduction / Overview

System Hub: Serves as the central management engine within the VM600 system, orchestrating data flow between dynamic measurement modules (e.g., MPC4) and external control interfaces.

Dual Protection & Monitoring Support: Handles system configuration, status logging, and communication routing without interfering with hardwired safety trip logic.

Redundancy Capability: Designed for high-reliability applications; supports redundant CPUR2 card configurations to maintain active communication during hardware servicing.

Flexible Communications: Connects seamlessly to external monitoring networks via Ethernet and serial industrial protocols (Modbus RTU / Modbus TCP).

Technical Parameter List

Product Features / Core Advantages

Modular Configuration Engine: Centralizes system parameter uploads/downloads for all adjacent processing cards across the VM600 backplane.

Hot-Swappable Design: Allows insertion and removal without shutting down power to the rack or interrupting critical hardware protection relays on MPC4 modules.

Integrated Diagnostics: Front-panel LED indicators display operational status, CPU activity, network link states, and communication fault conditions in real time.

High Availability Redundancy: Paired with an IOCR rear card, CPUR2 supports dual-redundant controller setups to eliminate single points of failure in mission-critical applications.

Model Classification

CPUR2 (Standard Controller): Standard processing unit handling basic rack management, network communications, and VibroSight integration.

CPUR2 / Standard Ordering Options:

Option A1: Standard configuration for basic machinery protection communication.

Option A2: Enhanced buffer memory and extended protocol activation for intensive condition monitoring systems.

Companion Module: Works directly with the IOCR (Input/Output Communication Card) mounted on the rear of the rack to output physical serial, Ethernet, and relay diagnostic connections.

Environmental Tolerance Conditions

Operating Temperature: -25°C to +65°C (-13°F to +149°F)

Storage Temperature: -40°C to +85°C (-40°F to +185°F)

Relative Humidity: 5% to 95% non-condensing

Vibration Resistance: IEC 60068-2-6 test standards (10 to 150 Hz, 2g continuous)

Shock Resistance: IEC 60068-2-27 test standards (15g, 11 ms duration)

EMC Immunity/Emissions: IEC/EN 61000-6-2 (Industrial Immunity) and IEC/EN 61000-6-4 (Emissions)

Installation Method

Slot Selection: Power down or verify rack status. Identify slot 0 (or designated CPU slot) on the front of the VM600 ABE04x rack.

Card Alignment: Align the CPUR2 circuit board edges with the top and bottom guide rails of the designated rack slot.

Insertion: Slide the card smoothly into the slot until the rear DIN connectors engage firmly with the backplane.

Fastening: Tighten the top and bottom front-panel retaining screws to secure the card and ensure grounded electrical continuity.

Rear Module Pair: Ensure the matching IOCR interface card is aligned and securely screwed into the corresponding rear rack position.

Operating Instructions

Initial Setup: Connect a host PC running VibroSight or VM600 MPSx software to the CPUR2 front diagnostic port or IOCR rear Ethernet port.

Network Assignment: Assign a static IP address, subnet mask, and network gateway using the configuration utility.

Firmware & Config Push: Upload the system project file to configure rack slot assignments, sensor mapping, and Modbus address tables.

Routine Operation: Monitor front-panel LEDs during standard operation:

STATUS: Solid GREEN indicates normal CPU health.

ETHERNET / FIELDBUS: Flashing GREEN/YELLOW indicates active network traffic.

DIAG/FAULT: RED indicates an internal system exception or communication timeout.
