SCADA Solutions Compared: Process Control and Instrumentation vs. Results Engineering
When choosing a partner for SCADA (Supervisory Control and Data Acquisition) applications, two companies often pop up in the conversation: Process Control and Instrumentation (PCI) and Results Engineering. Both are respected names in the field of automation, controls, and real-time data systems. They offer similar services on the surface, but a deeper dive reveals key differences in focus, expertise, project scale, and customer support.
In this article, we’ll walk through what each company does, how they compare in SCADA project execution, and which business type or sector might benefit more from one over the other.
Let’s break it all down in plain language.
Who is Process Control and Instrumentation (PCI)?
Process Control and Instrumentation is a U.S.-based systems integrator with decades of experience in industrial automation. They specialize in control systems design, programming, installation, and commissioning for a variety of industries including oil and gas, water/wastewater, and manufacturing.
Their core expertise lies in working with SCADA systems, PLCs (Programmable Logic Controllers), and DCS (Distributed Control Systems). PCI places a strong focus on instrumentation and control, aiming to optimize operations through reliable system integration and process automation.
They pride themselves on being vendor-independent, which means they work with leading SCADA platform providers like Rockwell Automation, Siemens, and Wonderware to tailor solutions to client needs.
Who is Results Engineering?
Based out of California, Results Engineering takes a more consultative and results-driven approach to system integration. They focus on helping clients improve their bottom-line performance through smarter control systems. They also offer SCADA development and maintain a strong emphasis on data-driven decision-making, enterprise connectivity, and Industry 4.0 solutions.
While they do handle classical control systems and SCADA work, they’re often involved when businesses need to transition toward digital transformation — especially for projects that integrate SCADA with MES (Manufacturing Execution Systems), ERP, or cloud analytics platforms.
Results Engineering typically targets sectors like food and beverage, water/wastewater, and clean energy. They emphasize ROI, KPIs, and operational intelligence platforms that tie business goals directly into technology stacks.
SCADA Capabilities Comparison
Here’s a side-by-side view of how PCI and Results Engineering differ in SCADA implementations:
| Feature | Process Control and Instrumentation (PCI) | Results Engineering |
|---|---|---|
| Approach | Hands-on engineering focus with deep instrumentation expertise | Results-driven business focus that ties SCADA to ROI and analytics |
| Core Industries Served | Oil & Gas, Water, Manufacturing, Utilities | Food & Beverage, Water, Clean Energy, Pharma |
| SCADA Platforms Used | Rockwell, Wonderware, Siemens, GE, etc. | Ignition by Inductive Automation, Wonderware, AVEVA, FactoryTalk |
| ERP/MES Integration | Limited or provided through third parties | Fully capable, with a strong MES/ERP integration focus |
| Cybersecurity Expertise | Standard OT security practices | Advanced cybersecurity planning, including IEC 62443 compliance |
| Data Analytics & Dashboards | Basic HMI/SCADA visualizations | Advanced BI dashboards, cloud analytics, KPI tracking |
Strengths and Limitations of Each
Process Control and Instrumentation Pros
- Hands-on Practical Experience: Decades of experience in heavy industrial automation
- Vendor-Agnostic Solutions: Flexibility in choosing the right platform for each client
- Field Instrumentation: Strong skills in integrating sensors, actuators, and hardware
- Fast Deployment: Especially effective on medium-sized industrial projects
Process Control and Instrumentation Cons
- Might lack deep capabilities in enterprise-level integration (ERP, MES)
- Limited focus on business intelligence or KPI dashboards
- Cybersecurity offerings not as advanced as competitors
Results Engineering Pros
- Business-Result Orientation: SCADA projects focused around ROI and data transparency
- Strong Digital Transformation Support: Excellent at integrating SCADA with MES and ERP
- Advanced Data Tools: Real-time analytics, cloud dashboards, and predictive reporting support
- Cybersecurity Certification: Offers consulting on IEC 62443 and OT security
Results Engineering Cons
- More expensive upfront due to wider scope of work
- Longer project timelines, especially if data intelligence is prioritized
- Less experience with hardwired field instruments and physical installation
Which Company Is Right for You?
The right partner really comes down to what your business needs:
If you run a manufacturing facility that just needs reliable SCADA uptime, tight control loops, and automation with minimal extras — PCI is the safe and effective choice. They’re practical, responsive, and know how to get a SCADA job done without a lot of fanfare.
But if your organization wants to leverage automation for enterprise growth, data transparency, and improved customer service, Results Engineering could be a better match. They’ll not only deploy SCADA but also plug it into your business strategy.
Use Case Examples
Imagine a water treatment plant that needs to upgrade its control systems. PCI would come in, configure all necessary PLCs, design SCADA screens, and make sure everything runs smoothly with little downtime.
Now picture a mid-sized brewery that wants to scale operations and track quality in real time. Results Engineering can build a full ecosystem: SCADA, MES, cloud storage, mobile access, and KPI tracking to help management make better business decisions — not just keep machines running.
Customer Feedback and Case Study Insights
According to public reviews and client testimonials:
– PCI clients praise their reliability, on-time delivery, and technical flexibility. Many mention how responsive the PCI team is during commissioning.
– Results Engineering has glowing reviews from companies that made profitable gains after deployment. Clients appreciate their ability to connect shop-floor automation with boardroom goals.
A notable example is a clean energy firm that deployed Results Engineering to unify its sensor network, asset management system, and remote monitoring. The system not only improved uptime by 40% but also gave management insight into energy cost losses in real time.
SCADA Platform Preferences
Both companies are comfortable working with legacy platforms and newer technologies. That said:
– PCI commonly uses Rockwell FactoryTalk, GE Proficy, and Schneider’s EcoStruxure for industrial applications.
– Results Engineering often leads with Ignition by Inductive Automation — especially for multi-site, cloud-enabled applications.
Ignition is favored when scalability and IT integration are top goals, whereas FactoryTalk or Wonderware may be chosen for more structured, traditional environments.
Final Thoughts
In a world flooded with automation vendors and SCADA integrators, both Process Control and Instrumentation and Results Engineering stand out — but for different reasons.
If you value engineered robustness, fast deployment, and practical plant-level control, then PCI is worth considering. But if your company is strategic about digital growth and sees SCADA as a bridge to enterprise systems, Results Engineering will provide that analytical and value-based approach.
Each has earned its place in the market, and they cater to different types of industrial visions.
For businesses staring at automation challenges, the better choice will depend less on features and more on how you see SCADA fitting into your future.
