Siemens 6ES7315-2AF00-0AB0 CPU 315

Series#: Siemens

Product Details

SIMATIC S7-300 CPU 315-2 DP; exact order number 6ES7315-2AF00-0AB0.
48 KB integrated work memory for the CPU 315-2 DP 2AF00 generation.
First interface provides MPI communication for programming and network access.
Second interface supports PROFIBUS DP communication.
24 V DC supply for integration into an S7-300 rack.
Uses the memory-card (MC) generation specified for this CPU, rather than a newer MMC-based variant.
Compare PROFIBUS address, bus termination, hardware configuration and card type before replacement.

Overview

The CPU 315-2 DP adds a PROFIBUS DP-capable second interface to an S7-300 processor with 48 KB work memory. The 2AF00 hardware generation uses a memory card (MC); verify the installed card and STEP 7 project when replacing it.

Integration and replacement notes

This order number is different from 6ES7315-2AF03-0AB0 and newer 315-2 DP versions. Carry over only a compatible load-memory card and confirm the DP configuration, firmware and connected I/O in the original project. Interface availability does not make it a drop-in replacement for a CPU 315 with MPI alone.
