Open and fully documented application programming interface (API) gives you the option to quickly and easily implement all Unipi controllers into already existing software solutions.
Open API
Aside from Mervis, our officially supported software platform, an open API is provided for all Unipi controllers. API serves as direct access to all I/Os and communication interfaces of Unipi PLCs, representing a quick and easy way to implement your software or third-party solution into Unipi hardware.
OS Linux
Unipi controllers are based on the Linux open-source operating system, which is regularly updated to ensure maximum reliability and security.
EVOK

Unipi-developed set of web service APIs for easy access to all I/Os and communication interfaces of Unipi controllers and extension modules. EVOK supports a wide range of communication protocols and allows easy implementation of Unipi hardware into both new and existing software solutions. More detailed info about EVOK is available on this link.
Modbus TCP Server
Standard communication interface for controlling PLC inputs and outputs through the Modbus TCP protocol.

SysFS
A driver designed for accessing inputs/outputs on a filesystem level. SysFS is useful especially for quick development and debugging of programs, or for integration into programs running directly on Unipi controllers.
Node-RED – example of a third-party solution
Node-RED is an open platform for quick application development using preprogrammed nodes. The solution is suitable especially for quick development, prototyping or creating responsive user interfaces connected to cloud services. For Node-RED, Unipi provides operating system image and partial technical support. More info about the solution is available on this link.
