Siemens 6ES7315-2FJ14-0AB0 Programmable Logic Controller Module

The Siemens 6ES7315-2FJ14-0AB0 is a SIMATIC S7-300 CPU315F-2 PN/DP with distributed safety functionality, designed for safety-related control tasks within legacy S7-300 installations. It provides 512 KB of working memory to support the program and data needed for safety applications. For communication, the module offers an MPI/DP interface at 12 Mbps and a second Ethernet PROFINET interface that includes a built-in 2-port switch, enabling networked devices to be daisy-chained on the same PN network. A Micro Memory Card is required for program storage and project data, reflecting the unit’s compact, field-oriented data management approach. The device is cataloged as Edition 01 and is documented as of firmware version 3.1, aligning with Siemens’ safety-focused CPU315F-2 PN/DP specifications. As a fail-safe CPU in the S7-300 family, 6ES7315-2FJ14-0AB0 supports distributed safety configurations and PN/DP communication, making it suitable for safety-related automation tasks that benefit from integrated network connectivity and local fieldbus access. Typical applications include safety-conscious control scenarios in industrial automation where a compact, PN/DP-enabled CPU315F-2 model is appropriate for enforcing safety requirements across decentralized I/O and networked devices, while maintaining compatibility with existing S7-300 infrastructure.
