Vibro-Meter VM600 CMC16 – 16‑channel condition monitoring interface card for VM600 racks
The Vibro-Meter (Meggitt) VM600 CMC16 is the condition monitoring card that ties your VM600 protection measurements to plant historian and analytics software. From my experience, it’s the piece you add when you want rich, time-synchronous vibration and process data streaming over Ethernet without disturbing your protection logic. It typically sits in a VM600 rack slot and aggregates up to 16 channels of dynamic/static data from compatible monitoring modules, then serves that data to VibroSight or your DCS via standard protocols.
One thing I appreciate is how the CMC16 reduces wiring clutter—data stays on the backplane, and you just pull out a single RJ‑45 for acquisition. You might notice that trend and waveform fidelity seem steadier during long runs; that’s partly because the CMC16 was designed for continuous, deterministic data transfer rather than one‑off snapshots. In many cases, users drop it in to unlock condition monitoring without touching the existing protection configuration.

Key Features
- 16‑channel condition monitoring aggregation – Typically collects dynamic vibration and related static parameters from VM600 measurement cards over the rack backplane.
- Ethernet data streaming – Outputs time-synchronous data to VibroSight and, in many cases, to DCS/SCADA via TCP/IP or Modbus TCP.
- No extra field wiring – Signals are acquired through the VM600 backplane, minimizing front-end rewiring and noise pickup.
- Front-access serviceability – Hot-swappable in most setups, with clear status LEDs for quick diagnostics during commissioning.
- Designed for mixed criticality systems – Keeps protection tasks separate on their cards, while exposing mirrored data sets for condition monitoring.
- Time alignment support – Supports network time stamping (NTP/SNTP) so multiple racks can be correlated accurately.
“We added the CMC16 to a compressor train already protected by VM600. Within hours, our reliability team was pulling orbits and high-resolution spectra into VibroSight without any changes to the trip path. It seems to be the most painless way to bring analytics online.” — Maintenance Superintendent, petrochemical plant

- VM600 CPUM (or CPUM Mk2) – Central processing/communication module for rack management; pairs with CMC16 when higher-level comms and rack control are required.
- VM600 XMV16 – 16-channel vibration measurement card (dynamic signals). The CMC16 typically reads its processed/static data for streaming.
- VM600 RLC16 – 16-channel relay output card for protection/alarming; not a data source itself but often used alongside a CMC16 in protection+CM systems.
- VM600 XIO / I/O modules – Process inputs (e.g., temperature, pressure) that the CMC16 can expose to software for trending.
- VibroSight – Meggitt’s software suite for online condition monitoring, trending, waveform capture, and diagnostics using CMC16 data streams.
Installation & Maintenance
- Rack & environment – Install in a VM600 19-inch rack inside a clean, ventilated cabinet. Keep ambient within 0–55 °C and avoid high vibration on the panel door.
- Grounding & shielding – Ensure rack and panel are properly grounded; maintain cable shields (especially Ethernet) to reduce EMI pickup.
- Networking – Use industrial-grade 10/100Base‑T switches. Enable NTP/SNTP so captured events align with DCS time; it makes diagnostics much easier.
- Commissioning – After insertion, verify front-panel status LEDs and confirm channel mapping from each measurement card in software. Back up the configuration file once stable.
- Routine care – Periodically clean front vents with dry air, review firmware/patch notes annually, and validate data latency and time sync during planned outages.
- Spare strategy – Keeping one CMC16 spare per site is usually enough; hot-swap capability means mean-time-to-repair stays low.
