Control System Engineering

New automation technologies and industry trends have been expanding the scope and value of automation. We understand the fit-for-purpose nature of this highly complex environment. Being vendor neutral allows Dexcent’s team of professionals to ensure that inter-compatibility of products and technologies are the design principles we use to engineer unbiased, non-proprietary, standardized, flexible, and expandable solutions.

Electrical and Instrumentation (PLAN & DO)

Electrical and Instrumentation components are the foundational building blocks of any automation system. When sizing, selecting and designing measurement, analytical, safety or control applications, Dexcent understands the fit-for-purpose nature of the hardware, instrumentation, communication protocol and supporting power and protection systems. During the design of a new or retrofit system, Dexcent can further support you in developing the best possible power designs, reducing process risks and increasing your control system life.

Instrumentation (Classical, Analytical, and Wireless)

Reduce process risks and increase control life with emerging technology.

Quantifying I/O and specifying what type of instrumentation (e.g. sensors, transmitters, valves and actuators) to be used to control the industrial process is one thing but realizing the impact of adopting emerging technologies is another. When selecting instrumentation for measurement, analytical, safety or control applications, Dexcent’s expertise is includes realizing that the instrumentation may also be subject to RF interference, highly caustic or corrosive environments, high humidity levels, vibrations, dirt and dust, or other conditions that challenge performance.

Power and Grounding Design for Equipment

Design critical power and grounding systems for control panels.

Effective power and grounding systems are critical for the protection of equipment. Designs and installations can be radically different for use in plants and in isolated areas. Leveraging our knowledge of ground loops and faulty power, Dexcent’s team is experienced in designing power and grounding systems for controls and computers which pose an even more unusual requirement than the grounding of power devices.

Control Valves Selection and Sizing

Ensure the right valves are chosen for each application.

Fluids within piping systems need to be controlled. Sizing and selecting the valve correctly has a significant impact on the proper operation of plants. Leveraging our experience in process operating conditions and control philosophy strategies, Dexcent’s team will ensure that the right control valve is selected for the application.

UPS Design for Control Systems Equipment

Ensure the power continuity requirements for the equipment are met.

Correct UPS system design is critical to ensure that the power continuity requirements for the equipment are met. Implementing a UPS solution keeps vital functions running for at least a short time and keeps your plant, people and environment safe when the power source is compromised. Dexcent’s team has experience designing UPS systems by finding a balance between unacceptable level of outages due to power events and excessive expenditure on high cost solutions.

Field Level Networks

Expertise, which covers wired and wireless communications protocols.

Designing a field level network takes more than common sense, it requires following proper media, protocol and data communication guidelines to ensure the information coming from your instruments and going to your end devices are accurate and reliable. Dexcent’s expertise spans from understanding the fit-for-purpose use of wired communication protocols, including classic I/O, 4-20mA HART, Profibus, Foundation Fieldbus and Modbus, and wireless communication protocols, including WirelessHART and Ziggbee.

Electrical Motor/Drives Control Applications

Ensure that the right motor and accessories are selected.

Electric driven motors are widely used in the process automation industry. Sizing and selecting the motor, starters, contactors, and VFDs correctly can have a significant impact on the life of the system. Dexcent’s team will ensure that the right motor and accessories are selected for the application.

Cabinet Design and Fabrication

Design custom instrumentation, control marshalling, or special application cabinets.

Working closely with industry proven cabinet fabricators, Dexcent designs instrumentation, control, marshalling or special application cabinets and junction boxes using proven standards and with consideration to enclosure rating, hazardous conditions, room layout, internal component layout, power distribution, heating/cooling, grounding and field factors (e.g. top hats, plinths, etc.).

DCS & Safety Integrated Systems (SIS) (PLAN & DO)

Modern automation systems have evolved into an Integrated Control and Safety (ICS) system consisting of a distributed system with control and safety functionality. Adding to the complexity is the convergence of the OT and ICS infrastructure and the under-rated importance of well-designed HMIs. Dexcent invests in developing highly specialized, cross domain-skilled and diverse teams capable of delivering technical and consultative expertise. In providing control system services, Dexcent has built a team of skilled engineers with practical know-how of most major automation platforms used today.

Process Control Systems (PCS)

Ensure the enhanced control strategy fits your objects.

Tighter profit margins and tighter performance limits mean less acceptance for tolerating inefficient processes and inefficient operations, so control systems and their performance continue to be subject to much more careful scrutiny than in the past. Achieving fewer process steps, less intermediate storage and less capacity within processing units add up to plants with much livelier performance. Changing equipment or hardware is expensive. Dexcent’s team with knowledge in instrumentation, field networks, controllers, redundant control network and system console (engineering, operator and application workstations) will ensure the enhanced control strategy fits your automation objectives. While designing or integrating PCS systems based on PLC, DCS, SCADA, Dexcent’s team uses a methodical approach with consideration to impact on safety, process, equipment, environment, people and cyber security at each major decision point.

System Integration

Integrate automation solutions in compliance with ISA standards; ensure effective connection with other systems.

Whether a project is being driven by the demand for increased energy-efficient production, the rising concern related to functional safety, or the demand for a software system to determine failures at the component level, Dexcent’s team of professionals design and integrate automation solutions in compliance with regulatory and ISA standards. Sometimes this means developing creative project team sourcing strategies inclusive of end users, suppliers, and speciality engineering firms.

Safety Instrumented Systems (SIS)

Implement successful ESD, BMS and F&G systems.

Even a single process plant accident can often be disastrous and result in multiple fatalities and significant financial losses. A Safety Instrumented System is designed to prevent high risk and high impact consequences. Danger of safety complacency during operations is a common industry challenge and is compounded by the confusion around technology choices, conflicting vendor stories and differing interpretations about what a dedicated safety system should do. Dexcent can lead this whole effort and guide you through the design lifecycle steps: Analysis (Risk Analysis, SIF Identification, SIL determination), Realization (Design, Installation, Commissioning) and Operation (Operation, Maintenance, Modification). From the sensor, to your logic solver and back to your actuation devices, your safety loops are safe with Dexcent. Dexcent’s team of professionals have experience implementing successful Emergency Shutdown Systems (ESD), Burner Management Systems (BMS), and Fire and Gas Systems (F&G).

Plant-Wide Data Historians

Design, collect, validate, store, and distribute information to the business and operational consumers.

The data collected from the multitude of sources available today provides true business and operational value only when the information is integrated into the network and made available to all end users in an actionable manner. Dexcent offers the full range of data management services required to design, collect, validate, store, and distribute information to the business and operational consumers.

Integrated Control and Safety Systems (ICSS)

Leverage cybersecurity knowledge to have a successful ICSS strategy.

New digital technology now makes it feasible to integrate process control and safety instrumented functions within a common automation infrastructure.  While this can provide productivity and asset management benefits, if not done correctly, it can also compromise the safety and security of an industrial operation.  This makes it critically important for process industry users to understand where to draw the line. For example to share field devices successfully, it is vital to understand the process under control – not just the safety equipment or the electronics, but the process areas that are being controlled. One must understand the process and how the devices are used, and understand how they fail and what will happen if they fail. Cyber security’s importance cannot be underestimated, particularly for safety and security of industrial processes.
