The utilized processor capacity which is available for the CFC can be checked under
2SWLRQ → 5HSRUWV in the register &KHFNFRQVLVWHQF\. By scrolling, an area is
reached, where information regarding the cumulated memory consumption of the
memory reserved for CFC can be read in percent. Figure 5-40 is an example showing
an over-utilization by 56 % in the task level PLC_BEARB (marked in the Figure), while
the other task levels are within the permissible range.

(refer to Figure 5-41). After acknowledgement of this alarm, the system utilisation can
be viewed as described above.
