# OTee- Open Architecture Real time Virtual PLCs

## 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.
