Measured results for calculating the performance of both operating modes

The measured values depend on the project, the equipment and load of the PC being used
and can differ from the times shown here. The times were calculated with the hardware
recommended by SIMATIC PCS 7.
Result, measured value (offline)
For the measured times, it is assumed that the step changes execute simultaneously and are
not processed with a time offset. Simultaneous step changes mean maximum load.

Result, measured value (online)
When processing the basic recipe described, a PC equipped with a size of the SIMATIC
BATCH online database has a 30% processor load.
Definition of step change: A step change means that a recipe phase was completed, a transition
run through and the following recipe phase was started. This means that at least 3 recipe
objects are involved in a step change. In practice, however, there are often more than 3 recipe
objects involved, for example in simultaneous branches, alternative branches or when there
is synchronization. As an average value, approximately 5-7 recipe objects are assumed per
step change.
