Using Ring Barrier Controller of previous version
From Vissim version 2022, Vissim saves all supply data to a *.prbc file. In previous versions, the supply data is saved to an external supply data file.
When opening an *.inpx file of a previous version that contains an RBC controller, the supply data will be converted automatically into the current *.prbc format.
