Step by Step debugging

In addition to the cycle by cycle execution mode, the debugger has a rich collection of powerful features for making step by step debugging in the source code of your application.

The step by step feature is completed by the possibility to place breakpoints in the source code of the application.


The debugger also shows you the call stack of called UDFBs and sub-programs when stepping. Step by step debugging is available:

  • in ST and IL text programs (a step is a statement)
  • in LD program (a step is a rung)
  • in FBD (a step is a graphic symbol corresponding to an action)
