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 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.

Designed for harsh environments, the SQ controller is rated for G3 corrosive environments and has an operating temperature range of -40 to 70°C.

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.

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.

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.

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.

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.
