Mixing safe and standard

Standard IO Modules can be mounted on

SafetyNet Nodes - together with SafetyNet

IO Modules - without affecting the node's

functional safety performance. Only

standard applications can read data from

standard Modules, but both standard and

SafetyNet applications are allowed to write

to standard modules. This flexibility can

simplify hardware design, where the

physical constraints of the particular locality

demand such an approach.

Serial interfaces

The Open approach extends to Modbus

serial interface products - which can be

connected to any node (SafetyNet or

standard) by an RS485 connection.

As with data from standard IO Modules, this

data can be read by standard Controllers,

but not by SafetyNet Controllers. Both

standard and SafetyNet Controllers can

write to such devices.

Comprehensive

programming tools

The SafetyNet System is programmed using

the Workbench software package - in

common with the MOST Process Control

Products. In addition to providing the

options of programming the required safety

function in one of three IEC 61131-3

languages (Ladder Diagram, Function Block

Diagram and Structured Text) the package

also provides many useful tools to assist in

testing and commissioning.

Restricted access

Access to modify safety-related parameters

within the configuration and application

program must be restricted to authorised

personnel. The SafetyNet system provides a

number of layers and methods of providing

this protection. Only users with "Safety

Responsibility" can access the safety-related

aspects of the Workbench. Only computers

that the SafetyNet Controller identifies as

"trusted hosts" can download new

parameters. A download can only take

place when an "over-ride key-switch" is set to

the required position. And, if required, each

SafetyNet Controller can be protected by its

own password - without which access to the

safety parameters is denied.

Maintaining field instruments

Maintenance over-rides can be

implemented from operator workstations in

full compliance with the guidelines from

TUV. Users define - as part of the safety

application - the actions to be taken to

maintain a particular instrument and the

SafetyNet System then implements these

pre-defined actions.

HART capability

The SafetyNet System allows full access to

HART field devices for Emerson's AMS

maintenance software. (The first release of

SafetyNet will not have full HART capability,

contact MTL for further information).

Earth leakage detection

Earth leakage fault detection may be

implemented using the 8751-CA-NS

Controller Carrier in conjunction with an

input channel from an 8811-IO-DC Discrete

I/O Module. If ELFD is not required,

SafetyNet Controllers can be mounted on

8750-CA-NS Controller Carriers.

On-line changes

Where allowed by local practices - and

following adequate testing and approval -

new safety programs and configuration can

be downloaded on-line and in real time. In

some situations, this may be possible

without interrupting the operation of the

safety function

SafetyNet Controller - Runs the safety

application program and carries out

diagnostic checks to ensure it is operating

correctly. If a fault is detected, it will shut

itself down.

SafetyNet Module configured for digital

outputs. Obeys commands sent by the

Controller to set outputs. Internal

diagnostics check that the module is

working correctly. If a fault is detected, the

Module will set outputs to their safe state

of de-energised.

SafetyNet Analog Input Module monitors

the inputs and carries out internal

diagnostics to check that the module is

operating correctly.

SafetyNet Module configured for digital

inputs. Monitors the inputs and also

checks for line faults. Internal diagnostics

check that the module is operating

correctly

Harsh and hazardous

environments

The SafetyNet System is as rugged as the

other MOST Process Control Components:

-40ºC to +70ºC operating ambient

temperature; Zone 2 or Class 1 Division 2

hazardous area mounting; G3 corrosion

resistance; and enhanced shock and

vibration capability. The system will operate

in the most extreme environments found in

process industries, allowing remote

mounting and a truly distributed architecture

in even the most demanding situations.

Event Logging and Sequence

of Events Recording

The SafetyNet System has the same Event

Logging and Sequence of Events (SOE)

recording capability as the MOST Process

Control System. Data received from SafetyNet

Modules is time-stamped by the SafetyNet

Controller with a resolution of better than

200ms (this is dependent on the execution

cycle - small nodes will deliver better

resolution). Data from dedicated (non-SIL)

SOE modules is time-stamped with a

resolution of less than 0.25ms between

different channels of the same SOE module

and less than 1ms between channels from

different SOE modules. The SafetyNet

Controller can record up to 8000 events

before its event data buffer begins to be overwritten by new data.

Reduced cabling and

termination costs

In common with the MOST Process Control

Components, the SafetyNet System offers

users the opportunity to significantly reduce

their spending on wiring and termination

costs. Moving control and safety hardware

out of the control room and on to the plant

gives significant savings. The Field Terminal

design allows users to avoid unnecessary

spend on marshalling cabinets, cross wiring

and marshalling terminals. Integral tagging

and fusing further simplifies cabinet design

and installation.
