InduSoft (AVEVA) vs. Kepware (PTC): A Deep Dive into SCADA Solutions
When it comes to industrial automation, the importance of selecting the right SCADA (Supervisory Control and Data Acquisition) software can’t be overstated. Two major contenders in the SCADA landscape are InduSoft, now part of AVEVA, and Kepware, a key industrial connectivity platform developed by PTC. Both companies deliver robust technological solutions but serve different purposes in the broader automation environment.
InduSoft provides a comprehensive SCADA software development environment, which is widely used for developing HMI (Human-Machine Interface) and embedded systems in manufacturing and process control. On the other hand, Kepware is not a SCADA system by itself but is often an essential part of SCADA environments. It offers industrial data connectivity with its flagship product, Kepware KEPServerEX, which acts like a universal translator between hardware, software, and applications.
Let’s explore how these platforms compare across key dimensions like features, flexibility, industrial application, ease of use, pricing, scalability, support, and integration.
1. Company Overview
InduSoft (AVEVA): Founded in 1997 and acquired by AVEVA in 2013, InduSoft brings over two decades of engineering know-how. Their platform, AVEVA Edge (formerly InduSoft Web Studio), is designed for embedded and OEM (Original Equipment Manufacturer) applications. Its strength lies in offering complete SCADA, HMI and IIoT (Industrial Internet of Things) capabilities in small and scalable formats.
Kepware (PTC): Kepware Technologies, now a subsidiary of PTC, focuses on industrial automation data connectivity. It’s not a SCADA software per se but rather a platform for seamless data communication across heterogeneous systems using OPC and proprietary protocols. KEPServerEX, their crown jewel, is widely regarded as one of the most reliable data connectivity tools for industrial environments.
2. Core Functionality
One vital difference between InduSoft and Kepware is their core purpose.
InduSoft/AVEVA Edge offers full SCADA functionality. Developers can design dashboards, control panels, alarms, historical data trends, and real-time monitoring tools. In short, it’s a complete software suite that allows plant managers and operators to observe and control processes.
Kepware/KEPServerEX, however, is focused on connectivity. It allows SCADA systems—such as InduSoft, Wonderware, GE Digital, and others—to communicate with industrial hardware such as PLCs (Programmable Logic Controllers) and RTUs (Remote Terminal Units) across different vendors. It acts as an industrial data gateway tying the edge devices to enterprise systems.
Here’s a side-by-side feature comparison:
| Feature | InduSoft (AVEVA) | Kepware (PTC) |
|---|---|---|
| SCADA Functionality | ✔️ Full-featured SCADA system | ❌ Not a SCADA system |
| HMI Design Tools | ✔️ Advanced graphical tools included | ❌ Not applicable |
| Industrial Connectivity | ✔️ Basic drivers included | ✔️ Extensive protocol support (Modbus, OPC UA, MQTT, etc.) |
| IoT Support | ✔️ MQTT, REST APIs, Integration with cloud platforms | ✔️ Supports MQTT, OPC UA, RESTful data access |
| Integration Flexibility | ✔️ Integrates with several PLCs and databases | ✔️ Integrates with most SCADA, HMI, MES & ERP systems |
| Scalability | Best for small to mid-sized setups | Highly scalable; ideal for enterprise-level integration |
| Pricing Model | Licensed per tag/device/screen size | Modular; licensed per communication driver |
3. Industrial Applications and Use-Cases
InduSoft (AVEVA Edge) shines in environments where compact and flexible HMI/SCADA solutions are required. Its footprint is small enough for embedded systems, so it’s frequently used in:
- Water and wastewater management
- Food and beverage packaging lines
- OEM embedded solutions
- Energy distribution and monitoring
Its ability to run on Windows Embedded, Linux, and even Raspberry Pi makes it incredibly versatile.
Kepware’s KEPServerEX is well suited for large-scale industrial facilities needing to consolidate diverse automation protocols. Its most common applications include:
- Manufacturing plants with mixed PLC vendors
- Oil and gas upstream and downstream operations
- Utilities and power grids with legacy hardware
- Energy asset management systems
For example, in a steel plant using Allen-Bradley, Siemens, and Mitsubishi PLCs, Kepware allows seamless data communication, creating a single-point-of-truth for analytics platforms like Microsoft Power BI or AWS IoT.
4. Ease of Use and Learning Curve
InduSoft includes intuitive drag-and-drop tools for HMI design, animations, alarm configuration, and data logging. It’s geared toward engineers who may not be expert coders. While it also supports scripting in VBScript and C-style languages for advanced users, the platform tries to stay user-friendly out-of-the-box.
Kepware is much more configuration-based. Users don’t need to write code, but understanding OPC protocols and networking fundamentals is important. It may have a steeper learning curve for non-technical users, though system integrators and engineers typically find the interface highly predictable and robust once set up.
5. Interoperability & Protocol Support
Protocol support is one of Kepware’s biggest strengths. It supports over 150 industrial communication protocols, such as:
- Modbus TCP/RTU
- Allen-Bradley EtherNet/IP
- Siemens S7
- MTConnect
- OPC DA/UA
- MQTT & RESTful API
InduSoft also includes drivers for major PLC vendors and supports OPC UA/DA and MQTT, but for ultra-diverse environments, Kepware is hard to beat.
6. Pricing and Licensing
InduSoft’s pricing is accessible for small to medium operations. Licenses are typically based on:
- Tag count
- Number of screens
- Supported clients
Their competitive pricing makes it ideal for OEMs and edge-device deployment.
Kepware’s pricing follows a modular structure. You pay for:
- Base platform (KEPServerEX)
- Specific communication drivers (Modbus, OPC UA, etc.)
- Optional add-ons like IoT Gateway or Advanced Tags
While it might sound costlier at first glance, scalability and flexibility make the cost worthwhile in large industrial networks.
7. Support, Documentation & Community
InduSoft/AVEVA offers online documentation, video tutorials, forums, and global tech support. AVEVA also has a partner network for local support. Users have reported varying experiences with support responsiveness depending on region.
Kepware/PTC is widely praised for solid documentation and reliable customer service. The PTC community is active and supports integration with ThingWorx, PTC’s IoT platform, which expands its ecosystem considerably.
