About Trihedral Engineering Solutions
Trihedral Engineering Solutions, a Canadian-based company founded in 1986, is the creator of VTScada, a SCADA software platform that is well-known for its scalability, powerful features, and reliability. Widely applied across industries such as water and wastewater, oil & gas, manufacturing, and electrical utilities, VTScada is engineered for real-time monitoring and control of critical infrastructure.
Trihedral stands out for its commitment to continuous software development. They’ve managed to remain fiercely independent with a focused approach. Visit Trihedral’s official website to learn more about their offerings.
About Horner Automation Systems
Founded in Indiana, USA, Horner Automation Systems has been delivering integrated automation solutions since the 1980s. Their strength lies in merging hardware and software through fully integrated all-in-one controllers. Unlike traditional setups that separate PLCs, HMIs, and I/O, Horner’s solutions combine everything into compact, user-friendly units.
Their primary platform for SCADA-type control is called CsCAN-based OCS (Operator Control Station), designed for small to mid-sized systems. Ideal for OEMs and industrial users looking for simplicity and speed, Horner is popular in industries like packaging machinery, food processing, and solar energy. Visit their official site here.
SCADA Software Capabilities Compared
Both companies offer SCADA solutions, but their strategies—and capabilities—differ significantly.
Trihedral: VTScada Platform
VTScada is a full-featured software suite. It’s modular and can handle installations from a few hundred points to hundreds of thousands of I/O points.
- Native Redundancy: VTScada supports built-in redundancy across the architecture with no need for third-party tools.
- Integrated Historian: Real-time and historical data logging capabilities are built in.
- Thin Client Support: Offers mobile-accessible dashboards and full HTML5-based displays for remote monitoring.
- Alarm Management: Advanced alarm and event handling, filtering, acknowledgment, and reporting tools.
- Integrated Development: GUI, PLC drivers, security, and workflows are all managed from a centralized platform.
- No Coders Needed: Visual editors and point-and-click configuration make it user-friendly for non-programmers.
VTScada feels polished and enterprise-grade, designed for long-term scale and stability.
Horner: Smart Integrated Control Systems
Horner’s SCADA approach often relies on compact devices like the XL and XLe series that run their proprietary Cscape software.
- All-in-One Construction: PLC + HMI + I/O on one device, reducing complexity.
- Modularity: Easy to scale horizontally by adding new units.
- User-Friendly Interface: Touchscreens and resistive displays offer fast deployment in smaller systems.
- Integrated Control Logic: Uses IEC 61131-3 standards for ease of programming.
- Remote Monitoring Options: Basic mobile viewing with web publishing capabilities.
- Affordable & Compact: Ideal for OEM implementations and skids.
While Horner doesn’t offer a giant enterprise-wide SCADA system like Trihedral, they excel in simplicity and cost-effective control.
Industry Applications
It’s important to match the right tool to the job. Here’s a look at where these platforms shine:
Trihedral (VTScada)
- Water & Wastewater: Trusted by municipalities for treatment plants and distribution systems.
- Oil and Gas: Used in upstream and midstream operations for real-time monitoring.
- Power Systems: Monitors substations and power flow.
- Smart Cities: Integrated for traffic, lighting, and infrastructure management.
Horner Automation
- OEMs: Built into packaging machines, metalworking tools, and conveyor systems.
- Food & Beverage: Control and monitor batch processing, bottling, and labeling lines.
- Solar Energy: Track inverters, battery storage, and PV panels locally.
- Compact Systems: Ideal for small water treatment units and mobile infrastructure.
Software Support & Updates
Trihedral provides lifetime support with updates throughout the product’s lifecycle, with access to their online knowledge base and a strong user community. Technical support is highly praised for being responsive and detailed.
Horner, while not as robust in terms of enterprise-level documentation, provides support tailored to its compact automation style. They also offer email and phone assistance, including field application engineers who help set up initial configurations.
Usability and User Experience
Trihedral prioritizes a user-centered design with rich dashboards, high customizability, and zero-coding configuration for simple applications. VTScada is easier to modify than many equivalent SCADA systems, thanks to its object-oriented design principles.
Horner’s interface is more geared toward engineers familiar with ladder logic and IEC programming standards. You’ll need some controller and programming knowledge to get the most out of Cscape.
Security Features
Security is critical in SCADA systems. Both competitors take this seriously.
VTScada Security:
- Role-based Access Control (RBAC)
- Integrated SSL/TLS encryption
- Audit logs and anomaly detection
- Custom user permissions at application and object levels
Horner Security:
- Password-protected interfaces
- Secure user login in Cscape
- No cloud dependency unless configured
- Field-level security hierarchy for critical applications
While Horner covers basic application security well, Trihedral meets the standards required for critical infrastructure cybersecurity compliance.
Scalability & Licensing
Trihedral supports scalability from single-machine installations to sprawling enterprise networks, with modular licensing depending on the number of I/O tags and features selected.
Horner’s devices are designed for individual installations. You scale by adding more smart units—not by expanding software capacity, which may not suit large enterprise control projects.
Pricing: Cost-to-Value Ratio
Trihedral is priced according to capabilities. It costs more upfront but saves in ongoing costs through centralized control, easier upgrades, and lower integration needs.
Horner offers budget-friendly devices. Total cost of ownership is low, especially when hardware and software are bundled. However, it may require more labor to set up for multi-node systems, depending on the use case.
