The Siemens 6ES7315-6FF04-0AB0 is a failsafe Central Processing Unit (CPU) from the SIMATIC S7-300 series. As a CPU 315F-2 DP, it is engineered for safety-related automation tasks where high reliability and system integrity are paramount. This powerful module comes with a 256 KB work memory to handle complex programs and data. It features two integrated interfaces: a combined MPI/DP interface for programming and communication, and a second dedicated PROFIBUS DP interface that can be configured as a master or a slave. This dual-interface capability makes it highly flexible for building distributed control systems. The CPU requires a Micro Memory Card (MMC) for operation and is powered by a standard 24 V DC supply, making it a robust and versatile core for demanding industrial automation applications.
