S7 Mmc

You don't actually have to have the memory card just for the PLC to work in the 1200 like you've had to with the 300/400's. I've been using a 1214 DC/DC/DC for a couple of months with no memory card and it works just fine. If you're just using the PLC for testing or learning you won't need one.
 
But one needs when he needs to upgrade old ones to get SCL & Download @ run...

And what ever they are going to introduce in future firmwares...

Basically you just need it for now.
 
I don't use SCL so wouldn't know.

I did lie though, I have used one doing firmware upgrades. Forgot about that when I responded above.

Hello Friends,
I have a problem.
I have 512 kb S7 MMC and it does not work now.
I installed 512 kb img file from this site and tryed to write it to MMC card by using WinHex program but it is giving error by loading. it says "6716 sector did not find " something like that...

I saw that, in the phyisically sector numbers 6716 and logically sector numbers 6715...

now I dont know what I can do....

Maybe this will help someone...

I had the same problem with MMC card 512 kb. This card was formatted in external cardreader by Windows and it became 3,52 Mb (!) FAT. And I can't wrote image file of 15Mb on card 3,52 Mb. WinHEX said "Cant write 6716 sector".

Problem was solved by formatting card in another (notebook) cardreader (it became 16Mb). And then I had written image onto card. Now it work correctly with 315 PN/DP CPU.

Has anyone had any luck using Uwes S7 Image writer V1.0 or Uwes S7 Image reader V1.01 with Windows 7? I have used it lots on Windows XP and it works great, but I can't get it to work with Windows 7. Any suggestions?

Thanks
