5.8.1

Read-only memory

The physical read-only memory (eMMC) of the control has a limited number of write cycles. Retrieve the
current status of the read-only memory via the ctrlX CORE web interface:
Settings �� Information �� tab "Resources" �� Sensors" .
��
Notes on sensor values:
•
"0 - 10% of eMMC life time used" means that up to 10 % of the maximum write cycles can be used.
•
Create a backup if the value exceeds 80%.
•
Replace the hardware if the value exceeds 80%.
•
Use an external memory to extend the service life of the permanent memory.
•
The frequency of the refresh cycle depends on the service life of the memory. If a refresh cycle is
not possible anymore, data can be lost.
5.8.2

Fan

The maximum service life of the fan unit is 50,000 hours. The fan unit then needs to be replaced. For
the ordering data, refer to
