Hi, ok, thanks. The product number 6ES7 954 8LC04-0AA0 is a correct card for S7-1x00 family. And if the card is labeld as a 4MB, the CPU can only use 4MB. But like I said. The SMC does not extend the total load memory. Yes, you can store datalogs with DATALOG_CREAT on the card, but not exclusively. If the SMC is plugged into the cpu as program card, all project data (user program, hw-config, connection configs) are stored on the SMC. So the worst case is: your user program need 4MB, afterwards so sotrage is left for the datalogs. ***EDIT*** And the link to the firmware update from kst has nothing to do with the "load memory" the SMC or the internal "load memory" is used for. The firmware update increases the usable "work memory", which is a different storage/memory area again. Please have a look at the S7-1200 manual. The different memory locations/types are described there, also how the memory is used. There are also methods to calculate the necessary amount of load memory for datalogs e.g. Of course you have to search a bit, but the information are there. SIMATIC S7 S7-1200 Programmable controller-> CPU memory There are also chapters for datalogs and methods to calculate the necessary amount of load memory for datalogs e.g. Of course you have to search a bit in the manual, but the information are there. regards sancruz |
