CPU load
In the delivery condition the CPU load display is deactivated on all CX80xx devices (it is displayed with a
constant 10%). The CPU load display is deactivated because it accounts for a considerable portion of the
CPU load itself. The CPU load can be activated for brief diagnostic help; however, we recommend that you
deactivate it again after the diagnostics.
HKEY_LOCAL_MACHINE/SOFTWARE/BECKHOFF/TWINCAT/RTime/EnableRTimeMeasurement 0
deactivated, 1 activated
A TwinCAT restart of the CX80xx is necessary after making the setting.
Note
CPU load
The CPU load is calculated internally with 10 ms. The CPU load display may fluctuate very
strongly if one or more tasks exceeding 10 ms are used.
