Crystal OPC – SCADA & HMI Software
Practical SCADA for small and medium automation projects.
Crystal OPC is a flexible SCADA and HMI platform for monitoring, controlling and analyzing industrial, agricultural, aquaculture and research systems.
Crystal OPC has been continuously used since 2006 and is developed and supported by CrystalVision. It provides the core capabilities needed for real-world automation projects - graphical HMI screens, real-time data, historical trends, alarms, reports and PLC communication - without the cost and complexity of large enterprise SCADA platforms.
Everything you need to monitor and control your process - in one practical platform.
Monitor, Control and Understand Your Process
Crystal OPC connects to PLCs, sensors and other equipment and brings operational information into one central interface.
Operators and engineers can build customized screens to:
-
View real-time process values
-
Control equipment and processes
-
Display trends and historical data
-
Manage alarms
-
Generate reports
-
Analyze operational performance
The platform is suitable both for new automation projects and for modernizing existing control systems without replacing the installed PLC infrastructure.
Flexible Communication
Crystal OPC supports communication with:
-
Unitronics PLCs
-
Allen-Bradley PLCs
-
Modbus TCP devices
-
Modbus RTU devices
-
Network cameras
Multiple controllers and devices can be integrated into the same project.
Operational data is stored in a PostgreSQL database, allowing long-term storage as well as access for external applications, BI systems and custom integrations.
Historical Data, Alarms & Reports
Selected tags can be logged at configurable intervals and stored for long-term analysis.
Users can review historical trends, investigate events and compare process performance over time.
Crystal OPC supports:
-
Real-time alarms
-
Alarm history
-
Email notifications
-
SMS notifications through an external service
-
Scheduled reports
-
Custom report templates
-
PDF, CSV and Excel export
-
WhatsApp notifications are also planned as an additional external-service option.
Build Your Own HMI
Crystal OPC includes an editor that allows system integrators to create and modify HMI screens for each project. CrystalVision can also provide complete HMI and SCADA development as an engineering service.
Remote & Web Access
Crystal OPC is primarily a desktop SCADA platform, with optional cloud connectivity hosted on Microsoft Azure.
A web application provides remote, browser-based access to system information, with user accounts and access permissions.
The current web interface is designed primarily for remote viewing and monitoring. Process operation and control remain within the main Crystal OPC environment.

Designed for Practical Automation
Crystal OPC is used in projects ranging from individual machines and research systems to complete agricultural, aquaculture and industrial facilities.
It is particularly suited to:
-
Machine builders
-
System integrators
-
Small and medium industrial facilities
-
Aquaculture and agricultural systems
-
Research and pilot facilities
-
Water and infrastructure systems
CrystalVision’s control and automation experience also means that support is not limited to the software itself. When required, we can provide the complete system - from PLC programming and communication to electrical engineering, instrumentation and SCADA implementation.
