When user administration is switched on, the task runtime increases briefly (corrected from V1.10)

Corrected from:
Cabinet Controller c520 V1.10
Cabinet Controller c550 V1.10

Response of the new version:
The switched on user administration does not lead to a short increase of the task runtime on the Lenze controller after the start of the PLC processing.
 
What happens?
There is a sporadic increase of the task runtime by approx. 100µs within the first 6 seconds after the start of the PLC processing in the Lenze controller.
 
When does the behaviour occur?
The behaviour can occur when the user administration on the controller is switched on.
 
Which products are affected?
Cabinet Controller c520 from V1.9
Cabinet Controller c550 from V1.9

Short-term measures:
Select the settings for the watchdog and the task cycle time of the highest priority task so that a watchdog exception does not occur due to the increase of the task runtime. 
Alternatively, you can use firmware V1.8.
