Breakpoints

Overview

The View > Breakpoints command opens the Breakpoints view which provides an overview on the breakpoints set in the project. The breakpoint parameters are displayed and can be modified. The Breakpoints view allows you to add, remove, enable, or disable breakpoints.

The breakpoint parameters basically are those which have been set when creating a breakpoint by the Toggle Breakpoint command (default condition parameters are assigned) or via the New Breakpoint.../New Data Breakpoint... command (possibility to define certain conditions).

Element	Description	Example
Application	Name of the active application.	App1 [PLC:Plc Logic]
POU	Name of the POU containing this breakpoint.	PLC_PRG
Location	Breakpoint position within POU: line and column numbers (text editors) or network or element numbers (graphic editors); (Impl): In case of function blocks, it indicates that the breakpoint is in the implementation part of the function block.	Line 2, Column 1 (Impl)
Instance Path	Complete object path of the breakpoint position.	PLC.Application.PLC_PRG.FBinst1
Tasks	Tasks during the run of which the breakpoints should be noticed: (any) in case of no restriction (default), or particular task names.	MainTask, SubTask1
Condition	Conditional breakpoint: Definition of condition (number of hits) when the breakpoint should cause a break in processing. For possible entries, refer to New Breakpoint... New Breakpoint; (default: 1).	Break when the hit count is equal to 3
Current hit count	Indicates how often the breakpoint has been run through (hit) up to now.	3
