Yes it's too expensive. But nobody can tell why it is too expensive. In my opinion, I prefer to make logging on a PC using WinCC TIA is better and cheaper than using these SD cards. |

What I've gathered is Siemens purchases strict quality control manufactured SD cards with way more capacity than stated on the package. The card has some hidden data with serial number and such so it can be set with know-how protection & licenses. I do not know if the SD / MMC card manager on the PLC or PG/PC monitor the card for errors and reallocate spare storage as required to keep it fully functional, or if it double writes the data for a built-in backup??? But with extra capacity, it could certainly do that.
