I/O interface card  IOC4 Mk2  600-043

DESCRIPTION (continued)

default and condition monitoring functionality is

optional. For VM600Mk2 AMC10Mk2 + IOC10Mk2

modules, both machinery protection and condition

monitoring functionality are available by default. It is

important to note that condition monitoring

functionality also depends on the purchased

VibroSight ® software license.

The RLC16Mk2 relay modules (standard and SIL

versions) are optional modules used to provide

additional relays when the four user-configurable

relays per MPC4Mk2 + IOC4Mk2 module and/or the

two user-configurable relays per

AMC10Mk2 + IOC10Mk2 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;

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 Parker Meggitt’s

vibro-meter ® product line, and are compatible with

the same VibroSight ® machinery monitoring

software suite.

MPC4Mk2 + IOC4Mk2 modules and

VM600Mk2 racks

MPC4Mk2 + IOC4Mk2 machinery protection and

condition monitoring modules are used as part of a

VM600Mk2 rack-based monitoring system.

A MPC4Mk2 module is always used with an

associated IOC4Mk2 module as a pair/set of modules

and can be used in a VM600Mk2 system rack

(ABE04x) or a slimline rack (ABE056).

Both the MPC4Mk2 and the IOC4Mk2 are single-width

modules 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 (that is, one or more

MPC4Mk2 + IOC4Mk2 modules,

AMC10Mk2 + IOC10Mk2 modules, any associated

RLC16Mk2 modules, and a optional

CPUMMk2 + IOCNMk2 module), the main

communications interface is via Ethernet LAN

connectors on the front panels of the modules

(MPC4Mk2 or IOC4Mk2. AMC10Mk2 or IOC10Mk2. and

IOCNMk2), which are 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, a MPC4Mk2 or AMC10Mk2 module

can provide information such as measurement, alarm

and/or status data to a CPUMMk2 + IOCNMk2 module

which can then share the information via one of its

industry standard fieldbuses.

In a VM600Mk2 system, RLC16Mk2 modules are

controlled and operated by a associated MPC4Mk2 or

AMC10Mk2 module, as determined by the system’s

configuration. The VM600Mk2 rack’s Open collector

(OC) bus and Raw bus are used to exchange control

and status information between the MPC4Mk2 or

AMC10Mk2 and RLC16Mk2 modules, as required.

Relays

The MPC4Mk2 + IOC4Mk2 module includes 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

status (common circuit-fault relay (FAULT)) is used to

indicate a problem with the MPC4Mk2 + IOC4Mk2

module, as detected by the module’s internal

diagnostics (BIST).

In general, VM600Mk2 system relays can be

configured as normally energized (NE) or normally

de-energized (NDE), and latched or not latched, as

required by an application.

Most relays in a VM600Mk2 system are driven by

control circuitry that supports a VM600Mk2 system

safety-line, that is, a system-wide control signal that
