SIMATIC memory card
4.3 Data transfer with SIMATIC memory cards
Transferring trace recordings to the SIMATIC memory card
The "Save measurements on device (memory card)" function allows you to save trace
recordings on your SIMATIC memory card.
Note
Redundant system S7-1500R/H
The CPUs of the redundant system S7-1500R/H do not support the saving of measurements
on the SIMATIC memory card.
Response when number reached
The "Deactivate recording" parameter repeats the measurements until the configured
"Number of measurements" is reached.
The "Overwrite oldest recording" parameter replaces the oldest measurement with the latest
measurement when the configured "Number of measurements" is reached. Note, however,
that continuously writing data to the SIMATIC memory card shortens its service life.
