Hi CT,
Sorry for the delay. Here is the reply from the developer:
Yes of course is this possible.
If the xReq is triggered a new data set is written into the csv file. So just change the cycle time of the trigger condition.
For questions about apps in the PLCnext Store - like this data logger library app - it is recommended that you contact the app developer directly in the Store, using the "Contact Developer" button in the top-right of the App page.
