DESCRIPTION

Introduction

The VM600 CPUM and IOCN modular CPU card 

and input/output card is a rack controller and 

communications interface card pair that acts as 

a system controller and data communications 

gateway for a VM600 rack-based machinery 

protection system (MPS) and/or condition 

monitoring system (CMS) from Meggitt’s 

Vibro-Meter® product line.

Different versions of CPUx/IOCx card pair

Different versions of CPUx/IOCx rack controller 

and communications interface card pair are 

available, as follows:

• The CPUM/IOCN is the original version with a 

front-panel display and support for

Modbus RTU/TCP and PROFINET

(PNR 200-595-VVV-VVV).

• The CPUR/IOCR is a version with rack controller 

redundancy and support for Modbus RTU/TCP 

(PNR 600-007-VVV-VVV).

• The CPUR2/IOCR2 is a version with 

mathematical processing of fieldbus data and 

support for Modbus TCP and PROFIBUS DP

(PNR 600-026-000-VVV).

VM600 rack-based monitoring systems

The Vibro-Meter® VM600 rack-based monitoring 

system is part of Meggitt’s solution for the 

protection and monitoring of rotating machinery 

used in the power generation and oil & gas 

industries. The VM600 is recommended when a 

centralised monitoring system with a medium to 

large number of measurement points (channels) 

is required. It is typically used for the monitoring 

and/or protection of larger machinery such as 

gas, steam and hydro turbines, and generators, 

smaller machines such as compressors, fans, 

motors, pumps and propellers, as well as balanceof-plant (BOP) equipment.

A VM600 system consists of a 19" rack, a rack 

power supply and one or more monitoring card 

pairs. Optionally, relay cards and rack controller 

and communications interface cards can also be 

included.

Two types of VM600 rack are available: a VM600 

ABE04x system rack (6U) that can house up to 12 

monitoring card pairs, and a VM600 ABE056 

slimline rack (1U) that can house 1 monitoring 

card pair. VM600 racks are typically mounted in 

standard 19" rack cabinets or enclosures installed 

in an equipment room.

Different VM600 monitoring cards are available 

for machinery protection, condition monitoring 

and/or combustion monitoring applications. For 

example, machinery protection cards such as the 

MPC4/IOC4T machinery protection card pair and 

AMC8/IOC8T analogue monitoring card pair, 

and condition monitoring cards such as the 

XMV16/XIO16T monitoring card pair for vibration 

and XMC16/XIO16T monitoring card pair for 

combustion.

The RLC16 relay card is an optional card used to 

provide additional relays when the four relays per 

MPC4/IOC4T or AMC8/IOC8T card pair are not 

enough.

The CPUx/IOCx rack controller and 

communications interface card pairs (CPUM/

IOCN, CPUR/IOCR or CPUR2/IOCR2) are optional 

cards used to provide additional VM600 system 

functionality such as configuration management, 

“hot-swapping” with automatic reconfiguration, 

front-panel display, CPUx/IOCx card pair 

redundancy, fieldbus data processing, frontpanel alarm reset (AR) button, MPS rack (CPUx)
