Viewing controller statistics

Once a controller NCES has been generated you can get some basic information on the controller model by clicking on the menu item Controller Statistics in the Statistics menu. A small window will open displaying the numbers of modules, signal IOs and signal arcs in the controller model.

The controller statistics are displayed in the same way as the statistics of any other module. They can thus be viewed also in the same way by right-clickin on the controller module and selecting the menu option Show module statistics from the popup menu that appears.
