The VM600Mk2 CPUMMk2 + IOCNMk2 rack controller and communications interface module is designed for operation with the second generation of VM600Mk2 rack-based machinery protection system (MPS), from Meggitt’s vibro-meter® product line. The CPUMMk2 + IOCNMk2 module consists of central processing unit (CPU) and input/output (interface) modules that act as a system controller and data communications gateway for VM600Mk2 systems.

VM600Mk2 rack-based monitoring systems The vibro-meter® VM600Mk2 rack-based monitoring system is the evolution of Meggitt’s solution for the protection and monitoring of rotating machinery used in the power generation and oil & gas industries. VM600Mk2 solutions are 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 VM600Mk2 system consists of a 19″ rack, a rack power supply and one or more monitoring modules. Optionally, relay modules and rack controller and communications interface modules can also be included.

Two types of rack are available: a VM600Mk2 system rack (ABE04x, 6U) that can house up to twelve monitoring modules, and a VM600Mk2 slimline rack (ABE056, 1U) that can house one monitoring module. The racks are typically mounted in standard 19″ rack cabinets or enclosures installed in an equipment room.

CPUMMk2-+-IOCNMk2-1

Different VM600Mk2 monitoring modules are available for machinery protection, condition monitoring and/or combustion monitoring applications. For example, the MPC4Mk2 + IOC4Mk2 module supports both machinery protection and condition monitoring, the XMV16 + XIO16T module supports extended condition monitoring for vibration and the XMC16 + XIO16T module supports extended condition monitoring for combustion.

Note: For the MPC4Mk2 + IOC4Mk2 machinery protection and condition monitoring module, the machinery protection functionality is available by default, while the condition monitoring functionality is optional and depends on the purchased VibroSight® software license.

The RLC16Mk2 relay module is an optional module used to provide additional relays when the four user-configurable relays per MPC4Mk2 + IOC4Mk2 module are not sufficient for an application. The CPUMMk2 + IOCNMk2 rack controller and communications interface module is an optional module used to provide additional VM600Mk2 system functionality such as fieldbus communications (Modbus TCP and/or PROFIBUS DP); module data aggregation, processing and sharing; rack and/or fieldbus communications redundancy; front-panel alarm reset (AR); MPS rack (CPUx) security; system event and measurement event logging.

VM600Mk2 rack-based monitoring systems complement the VibroSmart® distributed monitoring systems that are also available from Meggitt’s vibro-meter® product line, and are compatible with the same VibroSight® machinery monitoring software suite.
