Setting and determining system diagnostics
4.2 Options for displaying system diagnostics
The "Online tools" task card provides an overview of the CPU state, the cycle time and the
memory usage.
● The "CPU operator panel" pane displays the current state of some LEDs and the mode
selector of a CPU.
● The "Cycle time" pane displays the cycle time diagram and below it the measured cycle
times as absolute values.
● The "Memory" pane contains the current memory usage of the associated CPU. The free
memory is shown both as a bar graph and as a numerical value (percentage).
The display for "Load memory" contains, in addition to the online project data (program
code, data blocks, hardware configuration etc.), all other data that may be on the
SIMATIC memory card, such as recipes, data logs, HMI backups or non-SIMATIC files
that have been copied to the memory card via the Web server of the CPU or offline in
Explorer (for example, PDF files).
