AVEVA Systems vs Tatsoft: A Deep Dive into SCADA Applications
When it comes to building scalable, secure, and future-ready SCADA (Supervisory Control and Data Acquisition) solutions, two major players stand out – AVEVA Systems and Tatsoft. Both offer powerful platforms tailored for industrial automation, energy, manufacturing, utilities, and more. Yet, although they both operate in the same space, their offerings and value propositions differ significantly.
Before diving into comparisons, let’s take a closer look at who they are.
AVEVA Systems, formerly known as Wonderware and now part of the Schneider Electric group, is a globally recognized industrial software leader headquartered in the UK. With decades of experience, AVEVA offers comprehensive digital transformation solutions, ranging from SCADA to data management and AI-driven analytics. Their solutions are widely adopted in sectors such as oil and gas, manufacturing, water utilities, and energy.
Tatsoft, on the other hand, is a U.S.-based company founded by industry veterans who previously worked at large automation firms. Their flagship product, FactoryStudio, offers a tightly integrated development environment for HMI/SCADA, IIoT (Industrial Internet of Things), edge computing, and industrial analytics. What sets them apart is their flexibility, open architecture, and commitment to performance.
Let’s unpack the differences between these two SCADA providers by exploring several key dimensions: architecture, ease of use, flexibility, pricing, and support.
1. Architecture and Platform Flexibility
Modern SCADA solutions must operate across traditional, on-premise environments and cloud-infrastructure. Here’s how the two companies compare in terms of architecture.
AVEVA:
AVEVA’s platform is robust but leans towards traditional system architectures, although recent updates such as their integration with Microsoft Azure have improved cloud capabilities. AVEVA System Platform offers a high degree of modularity but often requires integrators and complex deployment strategies.
Tatsoft:
Tatsoft’s FactoryStudio offers remarkable flexibility, especially for hybrid environments. The platform supports Windows, Linux, Azure, AWS, and even edge devices like Raspberry Pi and ARM processors. Thanks to their .NET and C# integrations, developers have extensive freedom to customize functionalities.
2. Ease of Use and Development Environment
SCADA development often requires engineers to design screens, manage tags, implement logic, and set up alarms and reports. How easy is it to do all this with each platform?
AVEVA:
AVEVA’s historic strength is in its user-friendly GUI and visual development tools. Engineers who’ve used Wonderware products feel at home. It’s well-documented with lots of online training and certifications available.
Tatsoft:
Tatsoft provides a highly integrated, single development environment for all modules — from SCADA to analytics — reducing the need to bounce between tools. It also offers a real-time debugging environment and script-driven customization.
Here’s how they stack up visually based on development speed and learning curve:
| Vendor | Ease of Use (1-10) | Learning Curve (1-10) | Development Speed |
|---|---|---|---|
| AVEVA | 8 | 6 | Moderate |
| Tatsoft | 6 | 8 | Rapid (with Dev Skills) |
3. Licensing and Cost Structure
Licensing strategies can be the make-or-break factor for many businesses.
AVEVA:
AVEVA uses a traditional seat-based or tag-based licensing model. While they offer scalability, prices tend to rise quickly as project scope grows. Smaller companies often find it too expensive for limited-scale implementations.
Tatsoft:
Tatsoft uses a much more flexible and transparent pricing structure. The platform offers excellent tag limits (up to 64,000+ tags) even on standard licenses, and the runtime cost is lower, making it friendly for startups and large enterprises alike.
4. Integration and Ecosystem
The ability to integrate with third-party systems and existing platforms is essential.
AVEVA:
Integrates well with Microsoft tools and Schneider Electric infrastructure. There’s also a large partner ecosystem providing trusted integrations.
Tatsoft:
Tatsoft wins in openness — it provides native drivers for OPC UA, MQTT, SQL, REST, .NET libraries, and even Python scripting. An ideal platform if you’re building IIoT or hybrid architectures.
5. Cybersecurity and Reliability
Digitalization brings growing risks. Both companies provide secure environments, but with nuances.
AVEVA:
With its long-standing industrial presence, AVEVA emphasizes system hardening, redundancy, and IT/OT security compliance.
Tatsoft:
Also takes security seriously — TLS, user access controls, encryption — but stands out in how rapidly updates are rolled out. As a younger company, Tatsoft can be more adaptive to emerging threats.
6. Support and Documentation
What happens when something goes wrong, or when you just need help setting up?
AVEVA:
AVEVA has a multi-national support ecosystem, including regional partners, consultants, and detailed product documentation. However, support may not always be immediate if you’re not top-tier.
Tatsoft:
Tatsoft offers direct access to engineers in many cases — a rare perk. Their growing community helps solve issues fast. However, they do have a smaller user base.
| Vendor | User Community Size | Response Time | Documentation Quality |
|---|---|---|---|
| AVEVA | Large | Moderate | Excellent |
| Tatsoft | Medium | Fast | Good |
Real-World Use Cases and Deployment Examples
AVEVA:
Used by companies like Shell, BASF, and Nestle. Common in large-scale water and wastewater systems, manufacturing lines, and power plants.
Tatsoft:
Deployed in agile environments such as packaging machines, medical device monitoring, and smart city edge control systems. Ideal for mid-sized manufacturers who need flexible integration with ERP or MES.
One interesting use case is a U.S. chocolate manufacturer who switched from AVEVA to Tatsoft for better licensing scalability across their eight facilities. The migration allowed them to scale at lower costs and develop custom dashboards with .NET that weren’t possible before.
The Final Verdict
There’s no one-size-fits-all answer here. Both AVEVA and Tatsoft offer highly capable SCADA solutions, but they serve different needs and audiences.
