How many breakpoints can you insert when debugging a program?

  • Entry
  • Associated product(s)

The maximum number of breakpoints that can be used is determined by the CPU used.

Four breakpoints:

  • All SIMATIC S7-400 CPUs
  • All SIMATIC S7-300 CPUs as from firmware V3.x
  • CPU 318-2 DP

Two breakpoints:

  • All SIMATIC S7-300 CPUs (except CPU 318-2 DP) with firmware lower than V3.x

If you have used up your breakpoint resources, you must first reset (delete) a breakpoint before you can set it at another point. Here you must note that breakpoints already run through continue to occupy resources. If you exceed the maximum number of breakpoints that can be used, you get an error message "D062 / D063" (resources exceeded).
