Kepware (PTC) vs OSIsoft (Now Part of AVEVA): A Deep Dive into SCADA Solutions
In the fast-evolving world of industrial automation, Supervisory Control and Data Acquisition (SCADA) systems are the backbone of operations. Two major players dominate the landscape: Kepware by PTC and OSIsoft, now integrated into AVEVA. Both provide robust SCADA-related technologies, but they differ significantly in architecture, use case suitability, pricing, integration capabilities, and how they serve industries such as oil and gas, manufacturing, energy, and utilities.
This article compares Kepware vs. OSIsoft in terms of SCADA compatibility, ease of integration, scalability, user-friendliness, and cost-effectiveness. Whether you’re a systems integrator, IT manager, plant operator, or business analyst, we want to help you determine which solution fits your goals better.
Company Overview
Kepware (PTC) is known for its leading industrial connectivity platform—Kepware KEPServerEX. Acquired by PTC in 2016, Kepware focuses on enabling connectivity between industrial automation devices and software applications. Kepware is highly valued for real-time data management, protocol conversions, and flexibility across vendor systems.
On the other hand, OSIsoft—now part of AVEVA—is best known for the PI System, a robust platform built to collect, store, analyze, visualize, and share large amounts of industrial sensor data. OSIsoft was acquired by AVEVA in 2021, significantly expanding its reach into hybrid cloud solutions and integration with broader AI and digital twin technologies.
What Exactly is SCADA?
Before diving into comparisons, let’s clarify what SCADA stands for. SCADA is a control system architecture that includes computers, networked data communications, and graphical user interfaces. These systems gather and analyze real-time data for monitoring and controlling plant equipment. In essence, SCADA makes manufacturing smarter, more efficient, and more cost-effective.
How Kepware Supports SCADA
Kepware’s KEPServerEX acts as a middleware platform, connecting industrial devices—like PLCs and sensors—to enterprise-level SCADA software. It’s designed not to replace SCADA but to feed it accurate, validated data in real time. One of its biggest strengths is compatibility—Kepware supports 150+ industrial communication protocols, making multi-vendor plant environments operate more cohesively.
- Modular Architecture: Add only the drivers and functionalities you need.
- OPC & MQTT Protocol Support: Flexible integration with different systems including modern IIoT platforms.
- Tag-Level Security: User-based access control per tag.
Because of this modularity, users in discrete manufacturing, marine operations, and energy plants favor Kepware for SCADA integration.
OSIsoft’s PI System in SCADA Environments
OSIsoft’s PI System, now a part of AVEVA, does much more than just support SCADA. It acts as an all-in-one data infrastructure platform, collecting data from multiple sources—including SCADA itself. The PI System not only stores and contextualizes real-time data but also integrates with advanced analytics and AI tools.
- Data Historian Capabilities: Unlike Kepware, PI System stores massive datasets over long periods with high compression.
- Integration with SCADA, DCS, and ERP Systems: See one single source of truth for operational data.
- Visualization Tools: Native integration with PI Vision for browser-based dashboards.
Businesses with advanced analytics ambitions or enterprise-wide data visibility needs often lean toward OSIsoft.
Comparative Table: Kepware vs OSIsoft for SCADA
| Criteria | Kepware (PTC) | OSIsoft (AVEVA) |
|---|---|---|
| Primary Role | Industrial Data Connectivity | Data Infrastructure & Historian |
| SCADA Integration | Feeds SCADA data (middleware) | Extracts, contextualizes, and stores SCADA data |
| Ease of Use | Simple UI, faster deployment | Greater depth, more training required |
| Protocol Support | 150+ Industrial Protocols | Multi-source data compatibility, but fewer device drivers |
| Storage Capabilities | No data storage (requires historian) | Built-in scalable data historian |
| Analytics Support | Limited | Advanced (PI AF, PI Vision) |
| Cloud Integration | Some support via ThingWorx | Strong integration with AVEVA Data Hub, AWS, Azure |
| Cost | Lower entry-point; driver-based pricing | Higher total cost; enterprise licensing |
Use Case Scenarios
Imagine you’re a small manufacturing firm upgrading from legacy PLCs. Your main challenge is connecting old Modbus-based devices to a new SCADA system. Here, Kepware shines. It bridges older protocols with new software and gets data flowing within days.
Now imagine you’re a global energy provider processing huge streams of real-time sensor data from thousands of remote sites. You not only need to monitor but analyze trends, detect anomalies, and present findings to compliance teams. For this, OSIsoft’s PI System fits best due to its powerful analytics, long-term historical storage, and scalable cloud support.
Pros and Cons at a Glance
Kepware (PTC)
- Pros:
- Easy to configure with intuitive UI
- Wide range of protocol support
- Affordable pricing model
- Well-suited for small to mid-size businesses
- Cons:
- Lacks native data historian
- Limited analytics tools
- May need APIs or additional platforms to scale
OSIsoft / AVEVA
- Pros:
- Enterprise-ready with strong data historian
- Powerful analytics and visualization capabilities
- Excellent system integrations (ERP, MES, DCS)
- Designed for large-scale operations
- Cons:
- High cost for smaller firms
- Steep learning curve
- Licensing can be complex
Industrial Adoption and Community Support
One interesting distinction is community engagement. Kepware has an active user base often integrated into solutions by OEMs and system integrators. The interface encourages plug-and-play, and its documentation is known for clarity.
On the flip side, OSIsoft’s ecosystem includes intensive academy programs, global hackathons, and deep engagement among data scientists and analysts. If you’re planning strategic digital transformation, OSIsoft certainly pushes the bar.
Security & Reliability
Security is a growing concern, especially in mission-critical systems. Both platforms have strong credentials:
- Kepware offers:
- Secure OPC UA, TLS encryption support
- Role-based authentication
- Log files for audit trails
- OSIsoft delivers:
- Strong support for data integrity over the cloud
- Multi-layer security framework
- Enterprise-grade failover and redundancy
Pricing Considerations
Kepware runs on a modular licensing model. You select drivers and modules individually, making it affordable at the start. Perfect for operations managers navigating strict budgets.
OSIsoft follows enterprise licensing with volume-based pricing. If you’re pulling thousands of tags across global operations, the initial cost is justified. But for smaller teams, it can be overwhelming.
Here’s a simplified view:
| Company Size | Suggested Vendor | Reason |
|---|---|---|
| SMB (Small/Medium Business) | Kepware | Lower cost, faster setup |
| Large Enterprise | OSIsoft / AVEVA | Built to scale, advanced analytics |
Integration Capabilities
Kepware integrates seamlessly with Microsoft SQL Server, Wonderware, Rockwell Automation, and even OPC UA servers like Ignition. It also connects with cloud applications using MQTT and REST APIs.
OSIsoft integrates deeply with AWS, Azure, AVEVA Insight, and even machine learning libraries using PI Integrator for Data Science. Access to contextual asset framework (PI AF) makes it plug-and-play for advanced predictive modeling.
For example, AVEVA’s native support with visualization and asset performance management platforms like Prism enhances OSIsoft’s power.
Final Thoughts
Deciding between Kepware and OSIsoft depends largely on the scale and maturity of your operations.
- Choose Kepware if you’re seeking cost-efficient device connectivity, simpler setup, and faster deployment without advanced analytics.
- Choose OSIsoft if your enterprise handles massive data, values deep insights, and is investing in full-scale digital transformation.
The truth is many SCADA systems work best when both solutions coexist. Use Kepware to collect and feed structured, real-time data—and OSIsoft to store, analyze, and gain insight from it.
