process_plantΒΆ

The process plant module contains the setup for the custom Cyber-Physical Process Plant. You can either create the plant manually per drag and drop in OMEdit or code it in the editor. The python API also hardcodes the process plants, based on the parsed plant-graphs.

The process plant script must include the first three lines. An equation statement and the last line. The code inbetween varies depending on the setup of your plant.

Process plant with one distill module plus source and sinks, created via drag and drop - including the positions of the blocks in the OMEdit diagram view

Warning

OpenModelica is not sensitive to indentation.

OpenModelica requires semicolons at the end of each line.
