Emerson VS3202 DeltaV SLS 1508 Redundant Logic Solver

Introduction

The DeltaV SIS™ process safety system has a uniquely scalable modular architecture that is based on the CHARMs

Smart Logic Solver (CSLS) and the unprecedented flexibility and ease of use of the Emerson Electronic Marshalling solution. 

Each CSLS provides I/O processing, Safety Integrity Level 3-capable logic solving, and diagnostics in a single logic solver.

The CSLS supports up to 96 local individually configurable channels, allowing flexibility for implementing safety

instrumented functions and is designed specifically for multi-core home run cables or field junction box installation.

All communications are completely redundant from the channel (LS CHARM) to the CSLS. Integrated HART® I/O

brings field diagnostics into the CSLS.

Benefits

Optimized process reliability: Emerson has extended DeltaV Electronic Marshalling technology to safety instrumented systems, 

with DeltaV SIS being a key component of the Smart SIS Solution.

Research shows that more than 90% of all faults in SIS applications occur in field instruments and final elements. 

The DeltaV SIS process safety system has the world’s first Smart Logic Solver using LS CHARMs. 

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.

Flexibility to meet project needs: Whether you have an isolated wellhead or a large emergency shutdown

(ESD) application, the DeltaV SIS system scales to provide you with the safety coverage you need for your SIL 1, 2,and 3 safety functions.

Each CHARMs Smart Logic Solver provides I/O processing, SIL 3-capable logic solving, and diagnostics. 

This means that processing power is added as the system expands. 

If the I/O limit is reached, a CSLS is added increasing memory and processing capacity along the additional I/O. 

This allows for I/O scalability without impacting the scan rate.

Modularity also provides isolation of safety instrumented functions (SIF). 

This isolation eliminates single-points of failure for improved availability and safety integrity.

DeltaV SIS components can be added online to facilitate system expansions.

PK Flex Controller

The DeltaV PK Flex Controller builds upon the ground breaking innovation and technology of the PK Controller.

It provides the same powerful functionality but with the added advantage of flexible capacity and a subscription

based license that will help reduce capital costs.

The DeltaV PK Flex Controller is configured like any other controller in a DeltaV system and can be installed as simplex

or redundant node. It can be used for applications in a wide variety of sizes, from 50 to 1500 Flex DSTs, depending on

which capacity customers subscribe to. For Ethernet-APL Device Control, 

the DeltaV PK Flex Controller can be used for a variety of Ethernet-APL Devices, supporting Modbus

TCP client or EtherNet/ IP interface in port P01 and PROFINET(PN1). 

P01 and PROFINET (PN1) can be enabled at the same time for greater functionality
