Mervis is a software platform for control of UniPi programmable controllers. Together with EVOK it is our officially supported software platform. Compared to EVOK (which is rather a basic driver providing access to different interfaces) Mervis is a set of tools and applications for advanced regulation and automation. Mervis is developed and allows programming methods in accordance with IEC 61131-3. It is compatible with UniPi v1.1UniPi Neuron and UniPi Axon control units and their extensions.

The license is not required to run Mervis; Mervis IDE programming interface can be downloaded for free on downloads.unipi.technology. The license is required only for connection to proxy server and the option to save data on Mervis DB online database. The database is not required, but represents one of the best available tools for data storage, monitoring and archiving for later evaluation.

Note: UniPi 1.1/1.1 Lite complete sets, UniPi Neuron and UniPi Axon controllers are supplied with the license request being part of the package.

For user already knowing the programming methods of this standard, it is easier to work with an unknown platform developed in accordance with this standard. Mervis is in accordance with this standard. It is possible to program it:

  • visually - via function blocks
