Old Form of the Breakpoint

By breakpoints you are able to stop the program at a specific position and let it process scan by scan. A breakpoint is inserted by programming the instruction

  HLT

If the virtuell PLC meets this operation it will interrupt the process of the program and display the CPU-window. The process of the machine simulation is stopped as well. In the CPU-window there is a button ‘Continue’. Each time you click it the scan is continued behind the breakpoint, the machine simulation is processed once and the program is processed from the beginning up to the breakpoint, then the simulation stops again. To delete the breakpoint delete the program line or put the comment sign ‘//’ in front of it. After that you have to transfer the blocks into the PLC again.
