When i try to active the web server i get a message that tell me that i dont have enough memory. I try to compress, but no sucess. I will change for a card of 2MB (6es7953-8ll31-0aa0). There is any card of 1 MB?? How much KB need the webserver? Thanks

If you want you just create a dummy project and check how much space does it takes. Attached you will find list of MMC card. Rite now check how much MB is used and try to figure out minimum how much memory is occupied for Web server after activating. Attachment S7-300_Memorycard_en.pdf (87 Downloads)

Please check how big your workmemory is of used CPU. You need at least a MMC which is one and a half time bigger then the workmemory. Then you can use the complete workmemory. Best regards, Wizard
