It packs 128 KB working memory, two interfaces (one MPI/DP and one DP), and an integrated 24 V DC power supply. A micro memory card is required to operate. This CPU handles 248 digital inputs and 124 digital outputs, with a maximum of 2048 bytes of address space and up to 4 racks of 8 modules each. Bit operations execute in 0.1 µs typical, and the interrupt response time is 400 µs. ## PROFIBUS DP and MPI connectivity Both PROFIBUS DP master and slave modes are supported on the DP interface, with a maximum transmission rate of 12 Mbit/s and up to 32 DP slaves or 32 nodes total. The MPI interface is also present for programming and HMI communication. The CPU mounts on a standard S7-300 DIN rail profile. Dimensions are 120 mm wide, 125 mm tall, and 130 mm deep — it occupies three module slots in the rack. ## End-of-life status and sourcing For a replacement, consult the Siemens S7-1200 or S7-1500 family for equivalent fail-safe functionality, or source this exact unit through the surplus market.","metaTitle":"Siemens 6ES7315-6FF00-0AB0 CPU 315F, 128 KB, EOL","metaDescription":"Siemens 6ES7315-6FF00-0AB0 SIMATIC S7-300 CPU 315F, 128 KB working memory, 2 interfaces (MPI/DP + DP).
