iQ-R PLC Data Logging SD Card Specifications and Questions

[Olly_J 7]

Hi All,

I need to start PLC Data Logging using an SD card in the CPU module for an iQ-R PLC.  I have not attempted this kind of logging before and I was wondering about any restrictions on the type of SD cards that can be used.

The documentation I have found says "SD/SDHC memory card: 32Gb maximum". Does anyone know why can't I use a 64 GB SD card ? (maybe due to addressing limitations?)

Also, when I look for SD cards, I see different speeds of data transfer such as 120 MB/s or 100 MB/s and I was wondering if there is any difference as far as the logging is concerned.  Does anyone know if there are any other restrictions, brands that don't work? Useful tips?

Cheers

Sandisk SDHC, industrial grade works perfectly. Kingstone is also ok, but always fast one and always industrial grade. I've made one time error and used slow SD card on HMI and never again.
