Hi
As UMENCHO said, this can be done manually. Then, In Step7 Micro/WIN, if you press "Compile All" button, in the Output window it shows how many bytes is your Program Block (Block Size = x (bytes), x errors) Then, you go to the S7-200 System Manual, and check page 3, where it states how many bytes Program memory each CPU has. If available program memory is higher than the compiled size, you get this CPU. Otherwise, as mentioned in the previous post, you get a memory cartridge. Hope this helps. P.S. In S7-1200 there is a feature you can use a MMC card as "Program Card", meaning that you can have a program up to 24 MB. This means that you will never again worry about program memory in your programming life. |
