Telemechanique sd memory card for M340

Why are these things anywhere from $150 - 250?

A unix bit by bit copy of the card doesn't work.

Anyone smart enough to reverse engineer the binary on the data portion to allow it to work w/ whatever is on the secure part?

This is b.s.

No, I'm using my own program, just can't see spending so much on an sd card to send updates out to so many customers. I work for an OEM.

Well you could ask the customers to use unity loader (free) and send them the files to download?

If you have Unity installation DVD, there should be tools-folder and SD card writer tool.

You can also download it, but this is (probably) not the newest version? So ask newer version from schneider or install it from Unity (v8) disk.

Does the SD card still have to be purchased from Schneider?

There comes 8mb card with every cpu, but I remember that Schneider rep sayed, that card don't need to be original. I haven't tryed it still if non original card works.
