Benefits

The World’s first smart SIS. Research shows that over 85% of all faults in SIS

applications occur in field instruments and final control elements.

The DeltaV SIS process safety system has the first smart logic solver.

It communicates with intelligent field devices using the HART protocol

to diagnose faults before they cause spurious trips. This approach increases

process availability and reduces lifecycle costs.

Flexible deployment. Traditionally, process safety systems have been deployed

either separate from the control system or interfaced to control systems via

engineered interfaces based on open protocols (e.g. Modbus).

However, most end users require a higher integration for configuration,

maintenance, and operations environment. DeltaV SIS can be deployed

either as interfaced to any DCS or integrated with DeltaV DCS.

Integration is accomplished without scarifying functional separation as safety

functions are implemented in separate hardware, software, and networks

while being seamlessly integrated at the workstations.

Introduction

The DeltaV SIS™ process safety system, part of Emerson’s smart SIS, ushers in the next

generation of Safety Instrumented Systems (SIS). This smart SIS approach uses the

power of predictive field intelligence to increase the availability of the entire safety

instrumented function.

Sequence of Events Capability

With DeltaV SIS process safety system, events are automatically generated as

function blocks are executed within a module scan. Events are time stamped 

with a resolution of <1 ms,and they are recorded in the sequence that they occur in the

Event Chronicle. When using standard function blocks such as input blocks,

|voter blocks, and cause and effect blocks, a standard set of events are

automatically generated without special configuration or programing required.

For example,I/O failures, trip limits, first outs, and other similar events are automatically

time stamped by function blocks and recorded in the Event Chronicle.

When a process variable exceeds the trip limit, DeltaV SIS records the event along

with the analog value and the trip condition.

In general, when there is a plant event that triggers anemergency shutdown from the SIS,

one input will exceed a trip limit on one scan and this will cause outputs to trip and

more inputs will then change state. Sequence of Events Recording has been

used to find that first input that caused the trip by looking at all of the inputs in the plant.

With the DeltaV SIS system, the operator simply filters the Event

Chronicle for first out trips, and the first-out is clearly visible.

If higher resolution is required for some channels then they canbe wired to both

the DeltaV SIS Logic Solver and also to a DeltaV Discrete Input Card for Sequence

of Events, which provides a resolution of 0.25 ms.

PCX Programming software allows these drives to be set up and running in a

matter of minutes. These drives are programmed with the same easy-to-use

PCX Programming Software used with standard FX Drives.

CE Mark FX Drives are also compatible with EMERSON Motion Control’s complete 

range of application modules. These modules provide FX Drives with additional hardware

and programming capacity to perform specificapplications.

Examples of these applications include press feed control, random infeed control,

phase synchronization control, and cam profiling control.

There are two methods of system wiring that meet or exceed the grounding and

shielding requirements set forth by the EMC Directive of CE. Both methods are demonstrated

in the diagram above.

The preferred wiring method utilizes special interconnection cables available from

EMERSON Motion Control. These cable components were specifically

designed to make use of a complete shield throughout multiple segments.

Connector backshells, bulkhead connectors and the cable itself work together

to reduce radiated emissions both inside and outside of the enclosure.

An alternate method allows for shielded motor feedback and power cable runs

inside metal conduit. This method is also effective in reducing radiated noise

and may be desired in some applications based on environmental conditions.

Regardless of wiring method chosen, power supply line and motor power filters are required.

Both are also available from EMERSON Motion Control.

Note that these servo systems are designed, configured and tested to meet

CE Mark specifications. In addition to the servo drives and motors,

EMERSON Motion Control also offers filters and cables that satisfy

compliance of the entire servo drive system.

FX Drives with the CE Mark designation have the same features and performance

specifications as EMERSON Motion Control’s popular FX Drives.

PCX Programming software allows these drives to be set up and running in a

Recently, the use of individual control products in Europe requires conformance

to standards recognized by the European Union (EU) member states.

These standards were designed to allow quick and fair market access throughout

the EU. The Electro-Magnetic Compatibility (EMC), directive – 89/336/EEC,

requirement placed on vendors is one of the toughest standards

regulating electromagnetic emissions and noise immunity.

Briefly, the EMC Directive states that components, such as servos, are considered

small portions of larger machines and therefore may not need individual compliance.

It would then be the machine builder’s responsibility to conform to the EMC Directive

for machines going into Europe. This approach, taken by many servo manufacturers,

places compliance burden completely on the machine builder.

Product testing by the machine builder will therefore be an excessively large expense.

The fact that EMERSON Motion Control products already posses the CE Mark is a distinct

advantage for machine builders. New models in our popular FX Drive series cover continuous

torque ratings ranging from 8 to 120 lb-in.

These models  include the FX-208CE through the FX-6120CE.
