Hi, The memory card you mention is compatible with your cpu: 6ES7952 1KK00-0AA0 6ES7952-1KL00-0AA0 Also see: You either use RAM og EPROM card in the cpu. With a RAM card, you need a battery backup in the power supply in case the power disappears. Otherwise the program will be lost. With an EPROM card, the program will not be lost when you turn off the cpu so there is no need for battery. There are two ways to replace the memory card. One is to write the program to the new card with an eprom writer first and then turn off the cpu and change the two cards and turn on the cpu. The other is to turn off the cpu and exchange the two cards and turn on the cpu. The cpu will now take a long time (up to 15 minutes) to get ready. Then you can use Step7 to download the program to the EPROM card via the cpu. |
