Introduction

The VM600Mk2 MPC4Mk2 + IOC4Mk2 machinery protection modules are designed for operation with the second generation of VM600Mk2 rack based machinery protection system (MPS), from Meggitt’s vibro-meter ® product line. The MPC4Mk2  + IOC4Mk2 are second generation modules (cards) that provide 4 dynamic and 2 auxiliary channels of machinery protection and basic condition monitoring in 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 balance of-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. Different VM600Mk2 monitoring modules are available for machinery protection, condition monitoring and/or combustion monitoring applications. For example, machinery protection modules such as the MPC4Mk2 + IOC4Mk2 modules, and condition monitoring modules such as the XMV16 + XIO16T monitoring modules for vibration and XMC16 + XIO16T monitoring modules for combustion. The RLC16Mk2 relay module is an optional module used to provide additional relays when the four user-configurable relays per set of MPC4Mk2 + IOC4Mk2 modules is not sufficient for an application. The CPUx  +  IOCx rack controller and communications interface modules (CPUM / IOCN and CPUMk2 + IOCMk2) are optional modules used to provide additional VM600Mk2 system functionality such as configuration management, “hot-swapping” with automatic reconfiguration (to be implemented for VM600Mk2), front-panel display, CPUx  +  IOCx modules redundancy, fieldbus data processing, front-panel alarm reset (AR) button, MPS rack (CPUx) security, system event and measurement event logging, fieldbus communications (Modbus, PROFIBUS and/or PROFINET) and/or communications redundancy. Note: Different versions of CPUx  +  IOCx rack controller and communications interface modules support different combinations of VM600Mk2 system functionality. VM600Mk2 systems are compatible with CPUMk2 + IOC Mk2 modules. 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.

MPC4Mk2 +  IOC4Mk2 machinery protection modules and VM600 racks

The MPC4Mk2 + IOC4Mk2 machinery protection modules monitor and protect rotating machinery as part of a VM600Mk2 rack-based monitoring system. The MPC4Mk2 module is always used with an associated IOC4Mk2 module as a set of modules. Both the MPC4Mk2 and the IOC4Mk2 are single width module that occupy a single VM600Mk2 rack slot (module position). The MPC4Mk2 is installed in the front of a VM600Mk2 rack and the associated IOC4Mk2 is installed in the rear of the rack, in the slot directly behind the MPC4Mk2. Each module connects directly to the rack’s backplane using two connectors. Note: The MPC4Mk2 + IOC4Mk2 modules are compatible with all VM600Mk2 racks (ABE04x system racks and ABE056 slimline racks) and later VM600 racks.

System communications

In a VM600Mk2 system (one or more MPC4Mk2 + IOC4Mk2 modules and any associated RLC16Mk2 modules), the main communications interface is the LAN (Ethernet) connector on the front panel of each MPC4Mk2 module, which is used for used for communication with the VibroSight ® software running on an external computer. In a VM600Mk2 rack (ABE4x), the VME bus can be used to share information between modules in the rack. For example, an MPC4Mk2 + IOC4Mk2 module can provide information such as measurement, alarm and/or status data to a set of CPUMk2 + IOC Mk2 modules which can then share the information via one of its industry standard fieldbuses. In a VM600Mk2 system (one or more MPC4Mk2 + IOC4Mk2 modules and any associated MPC4Mk2 modules), the RLC16Mk2 modules are controlled and operated by a MPC4Mk2 , as determined by the configuration. The VM600Mk2 rack’s Open collector (OC) bus and Raw bus are used to exchange control and status information between the MPC4Mk2 + IOC4Mk2 and RLC16Mk2 modules.

Relays

The MPC4Mk2 + IOC4Mk2 machinery protection modules include five relays. The four user configurable relays (RL1 to RL4) can be used by a VM600Mk2 system to remotely indicate system alarm and/or status information. While, a common circuit-fault relay (FAULT) is used to indicate a problem with the MPC4Mk2 + IOC4Mk2 modules as detected by the internal diagnostics (BIST). The relays in a VM600Mk2 system (specifically one or more sets of MPC4Mk2 + IOC4Mk2 modules and any associated RLC16Mk2 modules), are driven by control circuitry that supports a VM600Mk2 system safety-line, that is, a system-wide control signal that automatically drives all system relays ( IOC4Mk2 and RLC16Mk2) and analog outputs ( IOC4Mk2) to a safe state should a problem be detected. In this way, IOC4Mk2 and RLC16Mk2 relays configured as normally energised (NE) can always be de-energised in the event of a problem with one of the components of the relay coil control signal. Note: This supports the “de-energise to trip principle” required in safety-related applications.

Software

MPC4Mk2 + IOC4Mk2 modules, as part of a VM600Mk2  system), are software configured using the VibroSight ® software. To meet stringent cybersecurity and API 670 requirements, MPC4Mk2 + IOC4Mk2 modules segregate machinery protection (MPS) and condition monitoring (CMS) by using separate configurations and different VibroSight configuration software: 

 • VibroSight Protect supports the configuration and operation of the machinery protection (MPS) functionality for a VM600Mk2 system. 

 • VibroSight Capture supports the configuration and operation of the condition monitoring (CMS) functionality for a VM600Mk2 system. 

 • Other VibroSight software modules support operations such as data display and analysis (VibroSight Vision), data logging and post processing (VibroSight Server) system maintenance (VibroSight System Manager), etc.

DESCRIPTION (continued)

More generally for extended condition monitoring system (CMS) applications, the VibroSight software supports the configuration and operation of XMx16 / XIO16T modules for condition monitoring and/or combustion monitoring, including the processing and presentation of measurement data for analysis. VibroSight  is also used to configure and manage CPUMk2 + IOCMk2 modules. Note: The VibroSight ® software is also from the vibro-meter ® product line. Applications information As part of a VM600Mk2 system, MPC4Mk2 + IOC4Mk2 machinery protection modules are ideal for the monitoring and protection of critical assets such as gas, steam or hydro turbines and other high-value rotating machines in a wide range of industrial applications.
