Vibro-Meter VM600 CPUM – Central Processing Module for VM600 Machinery Protection & Condition Monitoring

The VM600 CPUM is essentially the brain of the Vibro-Meter (Meggitt) VM600 rack. It coordinates measurement modules, manages communications, and keeps the system configuration and event handling under control. From my experience, if you need reliable, rack-level supervision with clean integration to DCS/PLC systems, the CPUM is the card that makes the rest of the VM600 hardware work as a coherent platform.

One thing I appreciate is how the CPUM centralizes configuration and alarms—so you don’t have to touch every measurement board individually. You might notice that commissioning typically goes faster because mapping alarms and statuses to Modbus is straightforward. A maintenance lead told us they swapped in a CPUM during a planned stop and were back online quickly, since the rack auto-recognized the existing module set after restoring the saved configuration.

Order Placement Process and Guarantees

Key Features

• Central rack management – Coordinates VM600 measurement and I/O modules, supervises status, events, and inter-module data.
• Ethernet integration – 10/100BASE‑T RJ45 for configuration, status, and data sharing; typically used to connect to DCS/SCADA via Modbus TCP.
• Configuration hosting – Stores and serves the rack configuration; simplifies backups and quick restoration after maintenance.
• Alarm and event handling – Concentrates system alarms, events, and health information for fast diagnostics.
• Time synchronization – Supports network-based time sync (commonly NTP) so event stamps align with plant historians in most cases.
• Service-friendly – Front-panel LEDs and service access help technicians verify communication and module states at a glance.
• Rack-powered – Draws power from the VM600 backplane (RPS6U), so no separate power wiring to the CPUM.

Technical Specifications

Related or Supporting Products

• VM600 RPS6U – Rack power supply module. Required to power the CPUM and all plug-in cards.
• VM600 XMV16 – 16‑channel vibration/dynamic measurement module for protection/monitoring; CPUM aggregates its data and alarms.
• VM600 XIO – Digital/relay I/O expansion; used when you need additional discrete signals to/from the rack.
• VM600 IOCN – Communications/gateway module used in some architectures; CPUM provides rack management while IOCN focuses on extended connectivity.

If you’re replacing a legacy CPU module, the CPUM typically drops into the same VM600 rack slot, and—after restoring the configuration—brings the module set back online with minimal rework.

Installation & Maintenance

• Cabinet & environment – Mount in a clean, dry control cabinet (19″ rack, 6U). Ensure adequate ventilation; avoid heat sources and vibration where possible.
• Wiring & grounding – Use industrial Ethernet cabling (Cat5e/Cat6) with proper shielding and connect rack protective earth per VM600 guidelines. Keep Ethernet away from high-voltage runs.
• Handling – Observe ESD precautions when inserting/removing the CPUM. Module replacement can typically be done with the rack powered, but follow site procedures and lockout rules.
• Configuration management – Back up the rack configuration before maintenance. After firmware updates, validate time sync and Modbus mapping.
• Routine checks – Periodically review event logs, confirm communication health (link/act LEDs), and verify that timestamps align with the plant server via NTP.
• Firmware – Keep CPUM firmware at the recommended revision for your VM600 module set; regression test during planned outages.

Quality & Certifications

• CE compliant; RoHS compliant
• Manufacturer operates under ISO 9001 quality systems
• UL/cUL recognition is commonly available for VM600 rack assemblies (availability can vary by build)
• Manufacturer warranty terms vary by region (typically 1 year); our supply warranty is 365 days as stated above
