Can RSC_Datalogger_PLM_4

PLCnext Technology & PLCnext Controls

Hello,
I’m using a PLCnext controller (AXC F 2152, firmware 2025.0) and would like to log a REAL variable periodically (e.g. every 30 seconds), including a timestamp for each sample.
I’ve seen the [RSC_Datalogger_PLM_4] function block and documentation, and it looks like it can record values to a database and export to CSV.
My goals:
Log a single REAL

  • variable from a running process
  • Add timestamp for each sample (in ISO 8601 format or similar)
  • Export the result as CSV
  • Open the CSV later in Excel
  1. Questions:
    Is this possible using RSC_DL_Pro from the RSC_Datalogger_PLM_4 library?
  2. What sampling configuration or strSinkProperties should be used for this?
  3. Is there a simple example for this use case?
  • If possible, I would appreciate a short example of how to configure:
    iFunction, udtSessionConfiguration, arrVariables
  • how to trigger periodic logging
  • and how to export the result (e.g., strExportFileName, iExportFormat)

Thank you!
