For critical process control applications that cannot tolerate interruptions, DeltaV systems offer controller

redundancy.

The redundant controller contains the same control strategy as the active controller.

A redundant link transmits control parameters to the standby controller

to ensure that it is ready to take over from the active controller.

parameters to the standby controller to ensure that it is ready to take over control if needed.

When redundancy is enabled, each module calculates the updates required by the standby controller.

These updates are transmitted to the standby controller via the redundant link.

These additional operations of controller redundancy Redundancy typically reduces CPU idle time by

about 10%. About 10 percent.

When a failure is detected, the standby controller can take over without affecting the process control

signals.

The DeltaV Event Chronicle stores a record of each switchover and the reason for the switchover, if a

reason has been determined.

Replacing an existing standby controller is as simple as removing the existing unit and installing a new

controller.

Replacing an existing standby controller is as simple as removing the existing unit and installing a new

controller.

The activated controller will detect the spare controller and the system will automatically debug and

download the new hardware.

Redundancy In addition to redundant hardware, a redundant license is required.

Redundant controllers Redundant controllers are shown as individual nodes in the Explorer window,

Designed for harsh environments, the SQ controller is rated for G3 corrosive

environments and has an operating temperature range of -40 to 70°C.

It is ideal for use close to process equipment.

It is ideal for remote installations close to process equipment.

For traditional installations using a central dispatch cabinet,

the CHARM I/O card can be installed in a standard I/O cabinet that provides electronic dispatch

capabilities.

The CHARM I/O card can also be used in highly distributed I/O applications.

The CHARM I/O card (CIOC) connects through the controller’s redundant Ethernet

ports to provide a highly distributed and flexible I/O solution called an e-solution.

solution. Up to 16 CIOCs can be connected to a single controller,

each providing up to 96 individually controllable signal types.

SQ controller capacity limits may vary depending on the specific application,

number of CHARM I/O signals, and control performance requirements.

Enhanced Memory Handling and Hardware Alarms, Indexed to Cover Capacity and Memory

Enhanced memory handling and hardware alarms covering capacity and memory

have been added to the SQ controller’s diagnostic information through indexing.

The WirelessHART I/O Card (WIOC) provides redundant communications

for up to 100 WirelessHART devices, ensuring high availability and reliability of wireless data.

Up to 16 WirelessHART I/O cards can be connected to a single controller, each providing up to 100

signals.

The controller automatically schedules control modules based on the assigned scan rate.

This allows each control function to be dynamically optimized for the process.

Module scan times can be set as fast as 100 milliseconds and as slow as 60 seconds.

The number of control modules that can be assigned to the controller depends

on the complexity and scan rate of each module, as well as the available CPU and memory.

The SQ controller is suitable for small to medium sized applications with up to 750 independent I/O

signals.

Product Description

The SQ Controller executes control logic based on process signals from the I/O subsystem

and provides communication with the rest of the DeltaV control system for operator interaction and data

collection.

Each controller node can be installed as a simplex or redundant node.

Each controller node can be installed as a stand-alone or redundant node.

Each controller node can be installed as a standalone or redundant node.

The controller is connected to an I/O carrier mounted on the right side of the controller carrier.

Up to 8 carriers can be connected to the local bus I/O.

Each carrier has 8 I/O cards for a total of 64 legacy I/O cards.

In addition to the 8 local input/output carriers, each controller can be connected to an additional 16 I/O

carriers.

Each controller can also communicate with an additional 16 remote I/O units that carry legacy card-based

inputs/outputs.

In addition to traditional I/O cards, the local bus supports Feldbus technologies including

Foundation Feldbus, Proffbus DP, DeviceNet and AS-i protocols.

The I/O subsystem also supports serial interface cards and Ethernet I/O interfaces.

The SQ controller also supports CHARM and WirelessHART I/O cards.

Inputs/Outputs

The S600+ is supplied with one I/O (P144) module with one Pulse Mezzanine (P148) module. 

This provides multiple digital, analog, and pulse inputs and outputs.

You can add two additional expansion modules to the S600+. 

The following expansion modules are available:

▪ I/O (P144) module – Provides additional analog and digital I/O.

▪ Prover (P154) module – Provides I/O for applications with a prover.

▪ HART (P188) module – Provides I/O for applications with HART transmitters.

▪ Pulse Mezzanine (P148) module – Provides pulse input capability.

Note: The Pulse Mezzanine module is installed as a daughterboard on an P144 or P154 module, and does

not use an additional module slot.

Configuration

Configuration of the S600+ is done through the same Windows-based intelligent

set-up tool as the S600 (Config600 Lite, Config600 Lite+, or Config600 Pro).

You can create or edit configuration files using Config600 Lite+ and

Config600 Pro (refer to Specification Sheet Config600). 

The S600+ provides the following functions through the Config600 configuration tool:

▪ Stream and station totalization.

▪ Batch totalization and retro-calculation.

▪ 3-term PID control with optional secondary control.

▪ Flow balancing.

▪ Flow scheduling.

Easy to Use

The DeltaV controller manages all control activities for the I/O interface channels and all communication functions with the zone control network.

The DeltaV controller manages all control activities on the I/O interface channels and all communication functions with the area control network.

Sequential control function block diagrams, sequential function diagrams,

and phasing logic provide powerful control structures that are further enhanced by user-defined structured text algorithms.

The controller time stamps alarms and events to accurately record the sequence of events.

The controller executes your control strategy at a rate of 100 milliseconds and transmits up to 4000 abnormal values per second.

Data Protection. All online changes made to control parameters are automatically stored for later upload to the engineering database.

In this way, the system always keeps a complete record of all data changed online.

Cold start. This function automatically restarts the controller in the event of a power failure.

Since the entire control strategy is stored in the controller’s NVM RAM, the reboot is completely autonomous.

Simply set the controller’s reboot state to the current condition.

Increased Productivity

Self-addressing.The DeltaV controller is unique in its ability to automatically identify itself within the

DeltaV control network.

When the controller is powered up, it is automatically assigned a unique address – no dip switches, no

connections – plug and play!

Automatic Location. The physical location of the controller is easy to find.

LEDs on the face of the controller can flash to provide a strong visual cue.

Automatic I/O Detection. The controller recognises all I/O interface channels on the subsystem.

As soon as an I/O interface is plugged in, the controller knows the general characteristics of the ffeld

device managed by that I/O interface.

This reduces the worthless engineering associated with configuration – simple!

Connection to electronic commissioning and wireless I/O.

Starting with DeltaV v14.3. CHARM and wireless devices connected via the CHARM I/O card (CIOC)

and the Wireless I/O card (WIOC) can be assigned to the MX controller.

This makes it easier than ever to add I/O to existing controllers by simply adding a CIOC and/or WIOC to

the DeltaV zone control network.

The I/O Module 

The I/O module includes an electronic module and a personality module or cavity insert.

The I/O module converts field signals into data and sends it to the controller.

Electronic module styles include digital and analog input and output modules,

contact inputs, RTD inputs, pulse accumulator / counter, HART input and output modules,

FOUNDATION Fieldbus, Profibus, DeviceNet, Ethernet and serial link controller modules. 

I/O modules offer a number of protective features including: 

▪ Signal conditioning, part of the surge-withstand feature, dissipates voltage “spikes” to protect the

electronics 

▪ Fuses protect the circuit in case of a short in the field device line 

Each module is “hot swappable,” allowing it to be removed and replaced without interrupting system

power or using mechanical tools.

The standard Ovation system configuration allows for up to 128 I/O modules in a local configuration.

This modular approach simplifies maintenance by requiring less assembly and offering a compact and

uniform architecture. 

Controller I/O Capabilities

The Ovation controller supports multiple I/O capabilities in various combinations, including: 

▪ Hardware I/O interfaces to Ovation I/O 

▪ Q-Line I/O plus software I/O in the form of simulated I/O 

▪ Virtual I/O generally communicated from OEM models and systems 

Ovation I/O has two methods of implementation: locally within the controller and remotely away from the

controller.

Remote I/O provides a means to distribute I/O throughout a plant.

Ovation I/O Architecture 

The Base

Ovation packaging reduces the system footprint by using base units which attach to mounting plates by

DIN rail;

these hold four independent Ovation I/O modules of any style.

This approach simplifies maintenance by making it easy to install, move or replace individual base units. 

Base unit features include:  

▪ Field terminal blocks that accept two 14 AWG or a single 12 AWG 

▪ I/O bus communications built into the base 

▪ I/O modules automatically addressed by location 

▪ I/O modules may reside in any location 

▪ I/O module redundant power distribution 

▪ No interconnecting cables for I/O bases 

▪ Built-in spare fuse holders and strip gauge in base 

The base unit’s high-impact plastic housing protects the backplane, exposing only the connectors as

modules are removed.  

Applications 

EDS is a powerful tool that simplifies information management by consolidating data from disparate 

systems into a single source for remote monitoring and analysis.  

EDS delivers increased awareness of plant operations by securely connecting staff to near-real time and

archived data,regardless of geographic location. Timely and accurate representation of plant performance

enables more informed decision-making to enhance operations and streamline maintenance.  

For example, severe weather events pose many forms of danger to any industrial process site,

which could require plant staff, both on and off duty, to quickly troubleshoot problems before they

escalate.

EDS provides critical process data to the right people at the right time, helping to mitigate emerging

issues. 

Using EDS data and tools, power generators can assess abnormal conditions that

could lead to infrastructure damage or widespread power outages.

Water plants can monitor increased flows within distribution networks to better predict flooding,

thus helping to prevent overflows and associated environmental impact. 

As an option, Ovation EDS can automate operator round activities,

including interfaces to computer maintenance or lab information systems and customized route and data

collection templates. 

EDS data can also monitor key performance indicators (KPIs) for

measuring against objectives and generating required performance reports. Example KPIs include: 

▪ Power generation: fuel usage, plant availability, emissions, generation revenue, or efficiency (heat rate). 

▪ Water and wastewater plants: quality, compliance, energy usage, chemical usage, or operating and

maintenance expenses. 

As an integrated information source, EDS provides valuable insights to all levels of an organization: 

▪ Executives or corporate management can obtain a complete view of district- or fleet-wide operations. 

▪ Plant management can view and trend information to make informed operating or maintenance

decisions. 

▪ Plant supervisors, engineers, and technicians can easily evaluate process or plant status.
