Storage
The Storage setting controls the maximum disk space the myPRO runtime may use for logging and historical data storage.

- Max. Storage Size — the upper limit in MB (default: 20 000 MB = ~20 GB). When this limit is reached, the oldest data is automatically deleted to free space.
- Unlimited — removes the size cap entirely. Use with caution on devices with limited disk space.
Click Save to apply. The change takes effect immediately without restarting the runtime.
