Trihedral Engineering Group vs. InduSoft (AVEVA): A Deep Dive into SCADA Solutions
Introducing the Contenders: Trihedral Engineering Group and InduSoft (AVEVA)
Trihedral Engineering Group, founded in 1986 in Nova Scotia, Canada, is the creator of the VTScada platform—an all-in-one SCADA (Supervisory Control and Data Acquisition) solution. The company is best known for offering highly reliable, scalable, and flexible SCADA systems primarily for industrial automation sectors like water and wastewater, municipal utilities, oil and gas, and manufacturing. Trihedral became part of Delta Electronics in 2020, which helped to sharpen its global footprint.
On the flip side, InduSoft, now a part of AVEVA, offers InduSoft Web Studio, a flexible HMI/SCADA and Embedded Automation tool. The company was founded in 1997 and was acquired by Schneider Electric in 2013 before AVEVA became its parent company. InduSoft’s strength lies in its openness and integration with embedded systems and small-scale devices, making it a favorite in niche and embedded automation markets.
Both companies have developed powerful platforms but differ significantly in approach, target markets, user experiences, and even configuration philosophies. Let’s dig deeper into their offerings, strengths, potential drawbacks, and where each shines best.
Platform Architecture and Flexibility
Trihedral VTScada is an integrated platform, meaning all core SCADA components—HMI, historian, alarming, reporting, redundancy, and development tools—come bundled in a single install. This reduces compatibility and versioning issues and enables a faster, more seamless setup across distributed systems.
By contrast, InduSoft Web Studio (IWS) functions like a modular toolkit. Users can select only the modules they need, offering higher flexibility but often at the cost of added configuration time and a steeper learning curve for beginners.
| Feature | VTScada (Trihedral) | InduSoft (AVEVA) |
|---|---|---|
| Built-in Components | All-in-one integrated platform | Modular, user selects modules |
| Ease of Setup | Quick with minimal configuration | Flexible but time-consuming |
| Embedded Device Support | Moderate | Strong, ideal for small footprint systems |
| Development Language | VTScada scripting, object-oriented | VBScript, C++, .NET compatible |
VTScada’s tight integration streamlines deployment. Having all tools in a synchronized ecosystem ensures fewer bugs and improved performance compared to a piecemeal approach like InduSoft’s.
User Interface and Visualization Tools
Both VTScada and InduSoft offer modern, customizable HMIs—but with key differences.
VTScada offers a built-in set of visual tools, emphasizing real-time feedback and dynamic controls. Its Idea Studio allows integrators to drag-and-drop active objects and configure them without writing much code.
InduSoft offers advanced visualization as well, but it relies more heavily on scripting compared to VTScada. With flexibility comes complexity. For example, creating a customized dashboard might require significant VBScript or .NET work.
VTScada provides native support for multi-monitor systems, high DPI displays, and mobile responsiveness—without requiring extra fees or third-party plugins.
VTScada Pros in UI:
- Seamless multi-monitor and mobile support
- Pre-built visual elements for rapid development
- Automatic scaling and layering
InduSoft Pros in UI:
- Highly customizable with VBScript and C++
- Lightweight for minimal hardware use
- Supports animations and advanced logic
However, new users typically find VTScada easier to adapt to due to its user-friendly UI builder and intuitive screen mechanics.
License Models and Cost
One of the biggest points of comparison is their pricing structure.
VTScada licenses are based on the number of I/O tags and typically include all core features. There’s no surprise pricing for basic features like alarms or reporting (which are optional add-ons in many other systems). Their licenses are also perpetual, with optional support renewals.
InduSoft has a tag-based and device-based model, but costs can vary depending on required modules. For example, adding mobile access, web viewers, or specialized protocol drivers may incur extra fees.
In terms of licensing transparency, VTScada wins by offering exactly what’s on the label—without upcharging for essentials.
Security and Compliance
Cybersecurity is critical in industries like municipal utilities, energy, and pharmaceuticals.
VTScada, being compliant with NIST SP 800-82 standards, provides encrypted user authentication, role-based permissions, and secure remote access out of the box.
It also supports:
- Active Directory integration
- Two-factor authentication
- Audit logging
InduSoft, while offering these capabilities, typically requires integration through third-party applications or middleware, increasing the attack surface if not configured properly.
So, while InduSoft can be secure, VTScada makes security part of its core infrastructure.
Industry Applications
VTScada is strongly suited for large-scale installations in industries that demand rock-solid reliability:
- Municipal water and wastewater
- Oil and gas operations
- Transportation systems
- Renewable energy monitoring
For example, the City of Kelowna in British Columbia has been using VTScada for its water systems with high uptime and automation coverage.
InduSoft shines in:
- Building automation
- Embedded machine control
- Medical devices integration
- Small and medium-size OEM systems
It’s an excellent choice for low-footprint applications where cost and flexibility matter most.
Customer Support and Community
Trihedral is famous for its top-tier technical support. Their North American support team responds quickly and personally. They also provide free training webinars and a certified integrator network.
Feedback from integrators often highlights Trihedral’s responsiveness and transparency.
InduSoft depends more on AVEVA’s global support ecosystem. While this offers broader resources and 24/7 support, the personalized touch is sometimes missing.
VTScada support includes:
- Phone and email support with real engineers
- Detailed application notes and video tutorials
- Global training partners
InduSoft’s community forum is active, and it provides extensive documentation, but users may sometimes feel “lost in the shuffle” when compared to VTScada’s boutique-style customer care.
Scalability and Redundancy
A huge strength of VTScada is its built-in native redundancy. All server nodes in a cluster share application data and switch roles automatically without interruption.
InduSoft does offer redundancy, but it typically requires additional licenses and complex configuration. If clients need auto-failover or real-time server sync, they’ll likely find VTScada a more stress-free solution.
In terms of scalability, VTScada can manage applications with over 1 million I/O with consistent performance. Parkland County in Alberta runs more than 400 remote stations using VTScada with minimal downtime.
International Reach and Localization
InduSoft’s major advantage lies in its internationalization. Since AVEVA is a global brand, InduSoft supports numerous languages and regional compliance tools.
VTScada, although primarily North American, now supports interfaces in multiple languages (French, Spanish, Mandarin), and supports international standards like OPC UA, MQTT, BACnet, and more.
InduSoft wins if you’re looking for international OEM deployment. VTScada wins if you seek high-end enterprise control in North America and Europe.
Mobile Access and Web Capabilities
VTScada includes mobile thin clients and tablet support by default. It also provides a dedicated tablet view that doesn’t require licensing add-ons.
InduSoft supports HTML5, MQTT, and mobile runtime licenses, but these often need to be purchased separately. Configuration is also more code-reliant.
Choosing VTScada means you’re “mobile ready” out of the box, which can significantly save both development time and total project costs.

Which One Should You Choose?
If you’re looking for a rock-solid enterprise SCADA system with seamless setup, strong redundancy, and intuitive use, VTScada is the clear front-runner. Its all-in-one structure ensures that you can grow your system from 100 tags to 1 million tags—without having to re-architect.
InduSoft, however, holds its ground in sectors where customization, cost-control, and embedded integration are paramount. For small-to-medium OEMs or international machine builders who need to create lightweight HMIs, InduSoft offers attractive advantages.
Many businesses combine solutions—using VTScada for central control rooms and InduSoft at the machine level for localized control.
In summary:
- Choose VTScada if you want centralized reliability, scalability, and rapid deployment.
- Choose InduSoft if your project is highly customized, cost-sensitive, or embedded-based.
