Hello, If customer allready has the program there is not mutch you can do that stay friends and give good service, then he will call you if in trouble. If you are afraid he sells your program, sorry it's too late. There is way to make it run only on this mmc and CPU. Read out the serial numbers with SFC51, do a compare if not o.k. you dont run the progam. How can you read out the identification data (the serial number of the MMC, for example) with the SFC 51 in STEP 7 V5.5? But in your case it's to late for that. Regards, Marcjan |
