Download new programs to a CPU
Verify that the CPU is not actively running a process before downloading a new program
Installing a new program causes the CPU to go to STOP mode, which could affect the
operation of an online process or machine. Unexpected operation of a process or machine
could result in death or injury to personnel and/or property damage.
After program data are copied to the program update folder, you can use the SIMATIC
Automation Tool to load new programs in one or more CPUs.
