OTee- Open Architecture Real time Virtual PLCs

In this article, we’ll show you a step-by-step live demo of deploying a fully functional Virtual PLC using OTee.io and a Revolution Pi as the edge device.

Virtual PLC made Easy using OTee

What is Virtual PLC?

• Virtual PLCs are software-based controllers that perform PLC operations on general-purpose hardware like Linux systems, enabling flexible deployment and easy management.

• OTee.io is a free platform for creating and deploying virtual PLCs, supporting IEC 61131-3 programming, Modbus TCP I/Os, and Linux-based edge devices like Revolution Pi.

Programming and Deployment

• OTee's structure text editor allows for efficient PLC programming using IEC 61131-3 compliant language, featuring tag definition, variable creation, logic programming, and alarm creation.

• The onboarding process for OTee involves adding a device, downloading an installer, running it on the edge device, and installing the OTee agent for real-time data exchange between the cloud and edge.

Communication and Monitoring

• Modbus communication in OTee enables connecting Virtual PLCs to a Modbus server on a computer, allowing remote monitoring and control of field I/O devices like temperature sensors.

• The tag browser in OTee facilitates remote editing and modification of tags, including temperature and heater values, for real-time troubleshooting and visualization of PLC program behavior.

Platform Features and Benefits

• OTee provides a centralized secure cloud environment for managing Virtual PLCs, offering role-based access control, industrial-grade open runtime, hardware agnosticism, and fleet management.

• CI/CD pipelines and community-driven libraries in OTee enable error-free testing and deployment of PLC programs, promoting open innovation and collaboration in industrial automation.
