DESCRIPTION (continued)

LEDs on the front panel of the CPUMMk2 module

(front of VM600Mk2 rack) indicate the mode of

operation and status of the CPUMMk2 + IOCNMk2

module, and the status of its system Ethernet and

fieldbus communications.

IOCNMk2 module

The IOCNMk2 module acts as a signal and

communications interface for the CPUMMk2 module.

It also protects all inputs against electromagnetic

interference (EMI) and signal surges to meet

electromagnetic compatibility (EMC) standards.

LEDs on the front panel of the IOCNMk2 module (rear

of VM600Mk2 rack) indicate the status of its system

Ethernet and fieldbus communications.

Fieldbus communications

The CPUMMk2 + IOCNMk2 module has two fieldbus

interfaces (ports), FIELDBUS1 and FIELDBUS2.

available on the IOCNMk2 module (rear of VM600Mk2

rack).

The fieldbus ports allow the CPUMMk2 module to act

as a data communications gateway between a

VM600Mk2 rack and external devices that use

fieldbus networks. In order to do this, the CPUMMk2

acts as a fieldbus server (slave) device that obtains

data from the modules in the VM600Mk2 rack

(MPC4Mk2 and XMx16 modules, and the CPUMMk2

module itself) to share with fieldbus client (master)

devices such as a DCS or PLC via one of the

CPUMMk2 + IOCNMk2 module’s fieldbus interfaces:

Modbus TCP and/or PROFIBUS DP.

Each fieldbus port, FIELDBUS1 and FIELDBUS2.

consists of two connectors, one for serial-based

fieldbus standards and one for Ethernet-based. Both

fieldbus ports can be active at the same time but only

one connector can be used per interface/port

(that is, connector J1 or J2 for FIELDBUS1. and

connector J4 or J5 for FIELDBUS2).

In addition, the system Ethernet ports support

Modbus TCP, which also allow the CPUMMk2 module

to share data from the other modules in the

VM600Mk2 rack.

The data to be shared by fieldbus can be

mathematically processed before it is shared and the

results of “data freeze” detection can also be shared

via fieldbus (defined by the fieldbus configuration

file)

IOCN

VM600Mk2 rack (CPUMMk2) security

The CPUMMk2 module supports features that can be

used to limit the functionality of a VM600Mk2 rack’s

machinery protection system (MPS) that is available

via the system Ethernet connections of the

CPUMMk2 + IOCNMk2 module. Enabling VM600Mk2

rack (CPUMMk2) security helps to reduce the

possibility of interference in the machinery protection

function of the rack itself and in the machinery being

monitored. Accordingly, CPUMMk2 rack security

makes it easier for operators to comply with

international security/critical infrastructure

regulations.

A security key lock on the front panel of the CPUMMk2

module is used to enable or disable VM600Mk2 rack

security as required. With security enabled, the

CPUMMk2 module will prevent (block) certain system

operations such as the uploading of configurations

and the sending of Modbus commands.

Relays

The CPUMMk2 + IOCNMk2 module includes two

output relays to remotely indicate system status and

alarm information. Each of the relays can be mapped

to any Modbus bit variable and are typically used to

signal a fault or a problem detected by a common

alarm, such as communication status or rack status.
