Processor Load
Original instructions
Introduction
The processor load (on the PC) caused by the entire simulation and the individual user tasks is shown here.
Process
This bar graph shows the actual processor load caused by the simulator process in percent.
Unlike the display in the Windows task manager which only indicates the current value, this bar graph indicates the average value over the time shown at the end of the bar graph.
The time entry at the end of the bar graph is the time that has passed since the simulator was started or since the last time reset was pressed.
Overhead
This bar graph shows the average processor load caused by the simulator process overhead in percent.
The overhead is calculated as follows:
load caused by the entire process - load caused by the user tasks
This can be an absolute or relative value for the processor load caused by the simulator. This setting can be made in the Display area.
The time entry at the end of the bar graph is the time that has passed since the simulator was started or since the last time Reset was pressed.
Mast ... Evt1T
The bar graph shows the average processor load caused by the individual user tasks in percent.
These can be absolute or relative values for the processor load caused by the simulator. The representation method can be set in the Display area.
The option button at the beginning of the bar graph can be used to select a user task. The details for this user task will be displayed in the Data in the user task area.
The time entry at the end of the bar graph is the time that has passed since the individual tasks were started or since the last time Reset was pressed.
NOTE: In case of a safety PLC, only the Mast task is enabled
Display: Absolute
If you activate this option button, the actual value is shown in the bar graph. This is shown as a percentage of the entire processor load for the PC.
Display: Relative
If you activate this option button, the relative processor load is shown in the bar graph. This is shown as a percentage of the processor load caused by the simulator.
Reset
If you press this command button, time measurements in this area are reset.
This is required to achieve a consistent representation of the times which have passed because the individual times are not started simultaneously when opening the simulator.
