Hi Experts,
What is the max size F Program in CPU.

The maximum F program size depends on the specific CPU model you are using. Here's a breakdown for common SIMATIC S7-1500 CPUs:
These limits apply to the total size of your F program blocks (FB, FC, and OB). Exceeding these limits will result in compilation errors.
For detailed information regarding specific CPU models, refer to the official Siemens documentation on SiePortal:
