ELPRO Technologies vs Kepware (PTC): A Deep Dive into SCADA Integration
Supervisory Control and Data Acquisition (SCADA) systems are the brain of modern industrial automation. From managing water treatment plants to oil refineries and manufacturing facilities, SCADA connects real-time data with decision-making processes. Two industry contenders stand out in this arena—ELPRO Technologies and Kepware by PTC. While they both specialize in SCADA integration, they cater to very different industrial needs and applications.
This blog aims to compare these two titans from the ground up, focusing on things like flexibility, ease of integration, protocol support, pricing, and overall suitability across industries.
Let’s take a closer look at these companies before we compare them head-to-head.
Who Are ELPRO Technologies and Kepware (PTC)?
ELPRO Technologies is a global leader in wireless monitoring and control solutions for industrial automation and IoT environments. Founded in Australia in 1983, ELPRO excels in wireless communication for critical infrastructure and remote environments. Their products are designed for high-reliability applications in water, oil & gas, mining, and heavy industries. Find them at elpro.com.au.
Kepware, a platform developed by PTC, is synonymous with OPC servers and industrial protocol communications. Their flagship offering, KepServerEX, supports an impressive range of protocols and devices, making it a go-to middleware for connecting disparate automation systems. Kepware is widely used in sectors like manufacturing, energy, building automation, and smart cities. Visit the official site at kepware.com.
SCADA Integration – Why It Matters
SCADA systems are only as powerful as their ability to communicate with field devices. This makes integration a critical decision-making point when choosing between ELPRO and Kepware. The quality of integration affects:
- Data accuracy and loss prevention
- System scalability
- Operational reliability
- Cybersecurity risk
Both ELPRO and Kepware approach SCADA integration from different engineering philosophies. Now, let’s get into how they stack up.
Communication Protocols – Who Offers More Options?
| Parameter | ELPRO Technologies | Kepware (PTC) |
|---|---|---|
| Supported Protocols | Modbus (RTU, TCP), DNP3, Profibus, IEC60870, Custom Wireless COT | Over 150 drivers including Modbus, BACnet, OPC UA, DNP3, IEC 61850, MQTT and more |
| OPC Compliance | OPC DA (through third-party middleware) | OPC DA, OPC UA, OPC Xi (native) |
Verdict: Kepware clearly takes the crown in protocol diversity. With extensive driver libraries, it’s easier to integrate Kepware into heterogeneous environments. ELPRO is more focused on core industrial protocols relevant to its wireless infrastructure, which is perfect for remote operations.
Ease of Integration
ELPRO Technologies prioritizes rugged deployments in remote or challenging environments. Their radios and gateways are plug-and-play, often with built-in support for Modbus and DNP3. While user-friendly, more complex integrations may require an external SCADA interface or PLC expertise.
In contrast, Kepware’s KepServerEX is a software-based platform that acts as a universal translator. Integration is smoother thanks to its graphical user interfaces, server-client architecture, and configuration wizards.
Example: If you’re deploying SCADA in a water treatment facility running on legacy PLCs, Kepware makes device mapping intuitive—even if devices speak different languages. ELPRO would be ideal if your infrastructure requires point-to-multipoint wireless setups in areas where fiber isn’t feasible.
Deployment Environment
ELPRO shines in physically demanding, outdoor, or remote locations. Wireless devices like their 900 MHz and 2.4GHz radios are weatherproof and designed to operate in extreme temperatures or under high electromagnetic noise.
Kepware is perfect for factory floors and urban installations needing tight integration with IT networks or enterprise applications.
- ELPRO: Think oil rigs, power substations in deserts, or mineral mines.
- Kepware: Think smart factories and enterprise-level HMI/SCADA integration.
Cybersecurity Features
| Feature | ELPRO Technologies | Kepware (PTC) |
|---|---|---|
| Encryption | AES-256 (over-the-air) | SSL/TLS, authentication, role-based access |
| Authentication | MAC-based, password-protected devices | Active Directory integration |
| Firewalls/Firmware Updates | Manual via USB or OTA update | Automatic updates, patch schedules |
Analysis: Kepware shines in handling modern cybersecurity threats, especially useful for IT/OT convergence. ELPRO offers solid physical-level security and radio-layer encryption but lacks broader enterprise-grade security management tools out of the box.
Licensing and Cost
Cost is a major factor when choosing between these two platforms, especially for small and mid-sized businesses.
ELPRO: Primarily hardware-based. The cost is predictable — you choose your radios, RTUs, or gateways. No subscription or licensing structure unless you integrate SCADA through third-party software.
Kepware: Software-licensed with modular driver pricing. You buy a base license and add drivers as needed. It can become expensive with scale, especially when hundreds of devices are involved.
Cost Tip: Kepware is cost-effective for businesses needing to integrate many devices using diverse protocols. ELPRO offers a more economical solution for fewer devices in rugged conditions.
Customization and Flexibility
Kepware offers high flexibility. You can create custom tags, map data points, apply scaling logic, display real-time trends, and integrate with analytics or cloud platforms.
ELPRO is more rigid in comparison but highly optimized for real-time wireless communications. If connectivity is the bottleneck, ELPRO delivers a seamless experience with low latency and customizable wireless mesh networks.
For example: Want to create a predictive maintenance dashboard combining temperature sensors, PLCs, and weather station data? Kepware makes that easy. If your priority is transmitting data from a pump station 10 miles away with no internet? That’s ELPRO’s wheelhouse.
Support and Community
PTC Kepware has an extensive ecosystem of user documentation, webinars, tutorials, and community forums. There’s also a dedicated technical support team with global reach.
ELPRO Technologies provides personalized support, especially valuable in long-term infrastructure projects. However, its global presence is somewhat limited compared to Kepware’s footprint.
Industry Applications – Where They Fit Best
ELPRO Industries:
- Water and wastewater treatment
- Mining operations

Real-World Comparisons
Case Study – Municipal Water Utility:
A city in Queensland, Australia needed to monitor 45 pumping stations over a 100km radius with limited cellular access. ELPRO’s wireless RTUs were deployed using 900MHz radios with zero monthly data fees and reliable performance. The system continues to operate entirely off-grid.
Case Study – U.S Automotive Assembly Plant:
This factory needed to connect legacy Allen-Bradley PLCs, temperature sensors, and modern Ethernet/IP systems. They chose Kepware for easy integration via OPC UA to their SCADA and MES systems, resulting in 30% faster data logging and improved OEE (Overall Equipment Effectiveness).
