Hello!

I am investigating the possibility of making a dedicate data logger with LOGO series PLC. What a want to do is to store values for a period of time (e.g. 1 month) and recycling them.  According to logo manual, it can record values and creates a file of 20000 lines stored in SD card. What confused me is the fact, that the maximum files that can be stored are limited to 50. Is there any way to overwrite the files so to have the latest 50 files in sd card? How to overcome this, any suggestions? Can S7-1200 overwrite data when MMC card is full?

 Thank -you.

George

Hi geoth,

please don't mix different topic. Please, use your other topic with the subject Data log recycling regarding the question about S7-1200.
