parkerVM600Mk2 MPC4Mk2 + IOC4Mk2 machinery protection modules

100 m at 100 Mbps, depending on Ethernet cabling.

For distances greater than the specified maximum, the Ethernet 

interface operates at reduced data transfer rates.

• Protocols : TCP/IP (proprietary protocols) for communication with a computer 

running software such as VibroSight

Internal (VME) • Bus interface : A24/D16 slave mode Note: In a VM600Mk2 rack (ABE4x), the VME bus can be used to share information between modules in the rack. For example, MPC4Mk2 + IOC4Mk2 modules can provide information such as measurement, alarm and status data to CPUMk2 + IOCMk2 rack controller modules which can then share the information via one of its industry standard fieldbuses. While in the opposite direction, CPUMk2 + IOCMk2 rack controller modules can issue alarm bypass (AB), alarm reset (AR) and trip multiply (TM) commands to MPC4Mk2 + IOC4Mk2 modules in the rack (when modules are Unlocked (maintenance operating mode)). VM600Mk2 module compatibility : The MPC4Mk2 + IOC4Mk2 modules are compatible with RLC16Mk2 modules as part of a VM600Mk2 system. The MPC4Mk2 + IOC4Mk2 modules include benefits and features such as improved measurement capability, VM600Mk2 system safety-line functionality and module diagnostics (BIST) that are not supported by the MPC4/IOC4T card pair. Note: In a VM600Mk2 system, the MPC4Mk2 module automatically configures MPC4Mk2 module relays as normally energized (NE) or normally de-energized (NDE), as per the configuration created using VibroSight Protect, whereas the RLC16 relay card uses jumpers on the card to manually configure the relays as NE or NDE. System communications External : System communication interface (Ethernet) for communication with VibroSight® software running on an external computer Internal – VM600Mk2 VME : VME bus interface for communication with controlling/processing modules via rack backplane. For example, with CPUMk2 + IOCMk2 rack controller modules. Internal – VM600Mk2 rack buses : Open collector (OC) bus and/or Raw bus to share and monitor RLC16Mk2 module relays, and distribute the system-wide safety-line control signal. Raw bus to monitor/share the RLC16Mk2 module’s status. Note: Generally, in a VM600Mk2 rack (ABE4x), the Raw bus is used to share dynamic input signals between processing modules, the Tacho bus is used to share tachometer (speed) input signals between processing modules, and the Open collector (OC) bus is used by processing modules to drive relay modules, all in the same rack. For example, the Raw bus and the Tacho bus are commonly used to share sensor signals (vibration and speed respectively) between different machinery protection modules and/or condition monitoring modules. Specifically for a VM600Mk2 system in a VM600Mk2 rack (ABE4x), the Open collector (OC) bus and/or Raw bus can be used to connect up to 32 outputs from a set of MPC4Mk2 + IOC4Mk2 modules to RLC16Mk2 relay modules in the same rack, if additional relays are required. External communication links/connections • Connection to a computer/network : The system communication interface (LAN connector on MPC4Mk2 module) can be used for connections/communications between the MPC4Mk2 module and a computer/network, using standard Ethernet cabling. See Connectors on page 17. • VibroSight® software : Used for the configuration of a VM600Mk2 system (one or more MPC4Mk2 + IOC4Mk2 modules and any associated RLC16Mk2 modules)

Configuration

MPC4Mk2/IOC4Mk2 modules : Software configurable via/over Ethernet, using a computer running 

the VibroSight® software.

Note: Jumpers on the IOC4Mk2 module are manually configured to 

select the VM600Mk2 rack’s Open collector (OC) bus and/or Raw 

bus lines that control and monitor the module’s relays, and 

distribute the system-wide VM600Mk2 system safety-line control 

signal. The jumper information is generated by the VibroSight®

software.
