Is it possible to program UNIPI in Node-red and at the same time also in Mervis IDE?
I am completely new to UNIPI systems (and to this forum). So, if my questions are basic (or in the wrong place), I would be more than happy if you could redirect me to the correct documentation where I can find my answers:
Is it possible to program UNIPI units with Node-red and at the same time using the Mervis IDE with IEC-61131-3 structured text?
If it is indeed possible can those two programs communicate with each other? Via some shared variable or some file?
I am mainly asking this because programming in Mervis IDE and IEC-61131-3 is more “industry robust” and Node-red would be used only for Cloud communication.
If my questions are too wide and the answers differ based on which UNIPI PLC I choose – I am currently thinking about NEURON, GATE and PATRON.
Thank you in regards for any answers!
Hello, Jakub, I have heard some rumors that There is a plan to implement paralel systems running on Unipi (especially Mervis + Node-red) to implement functionalities from Node-red with Mervis
let´ s hope that will be true in near future
Wow that's interesting!
In the meantime I will try to find any other way (for example Modbus TCP or some files).
I would be interested in a setup like this too
Currently this is possible by flashing Mervis OS and then installing Node-RED following the standard installation instructions: https://nodered.org/docs/getting-started/raspberrypi
However, this solution is not tested and we cannot guarantee that the Mervis RT will behave correctly if other such demanding SW is running on the controller.
