General Discussions / Memory card MMC
« on: April 26, 2005, 01:29:48 AM »
I use Siemens memory card MMC to transfer data between a computer and a S7 300. I would like to use standard MMC but it seems that is not possible because of formatting differences.
So, anybody would have information about these two formatting sequences?
 
Thank you for advance.

General Discussions / difference between PLC cables ??????
« on: April 22, 2005, 07:18:49 AM »
Anybody could explain what is the difference between S7 200 cable and S7 300 cable for S7 Siemens PLC?
I know these two cables must convert data signals from computer (RS232) to PLC (RS485) in order to program PLC...but I don't understand why they are different in the catalog...

Thank you for advance
