I’m working with PFCx00 and CODESYS V3. I want to log PLC-variable data cyclically in the local system. I could do it with CSV in datalogger, but maybe there are better options.
-If I want to save data in a database, which database do you recommend for this task?
-Are there any guides on how to handle it?
-How much data is reasonable to handle in a PFC200/PFC300?
Hello, you might consider Influx, which makes it simple to set a retention policy to manage the size of the database. There are Codesys libs to write directly, or you can use telegraf for ingesting data.
Another option is MariaDB, but it depends on the use case. A full SQL is kind of overkill for time based data in most cases.
With PFC200 you probably want to move your docker containers to an SD card, the PFC300 has plenty of flash for this however.
