Overview

This earlier S7-300 CPU 315 variant provides 48 KB work memory and an MPI programming interface. Its load-memory arrangement uses the corresponding memory-card generation, so it should not be confused with newer MMC-based CPU 315 variants.

Integration and replacement notes

The suffix 1AF03 identifies this exact hardware generation. Compare the CPU and memory card with the machine documentation before swapping: a CPU 315-2 DP adds a second network interface, while later S7-300 CPUs can use a different load-memory format.
