Downloading the elements of your program
You can download the elements of your project from the programming device to the CPU.
When you download a project, the CPU stores the user program (OBs, FCs, FBs and DBs)
in permanent memory.
You can download your project from the programming device to your CPU from any of the
following locations:
● "Project tree": Right-click the program element, and then click the context-sensitive
"Download" selection.
● "Online" menu: Click the "Download to device" selection.
● Toolbar: Click the "Download to device" icon.
Note
Downloading a program does not clear or make any changes to existing values in retentive
memory. If you want to clear retentive memory before a downlo
ad, then reset your CPU to
factory settings prior to downloading the program.
You can also download a panel project for the Basic HMI panels (Page 32) from the
TIA Portal to a memory card in the S7-1200 CPU.
