Hello YKR:

Since you provide no information on the type of panel you wish to use, here are 2 FAQs on external memory storage for Siiemens panels that should provide the information yiou need, including the part numbers for the Siemens cards:

Which external storage media can you use with the current SIMATIC panels and which memory card interfaces do they have?

Which external storage media can you use with the SIMATIC panels which have already been discontinued and which memory card interfaces do they have?
