Siemens SIMATIC S7-300 CPU 319F-3 PN/DP Fail-Safe PLC – 6ES7318-3FL01-0AB0

The Siemens SIMATIC S7-300 CPU 319F-3 PN/DP (6ES7318-3FL01-0AB0) is a high-performance fail-safe programmable logic controller designed for demanding industrial automation and safety-related applications. It supports standard PLC control alongside compatible safety functions for applications such as personnel protection, machine safety, and burner control.

With 2.5 MB of integrated work memory and three communication interfaces, this CPU is designed for complex automation programs and distributed control systems. The first interface supports MPI and PROFIBUS DP communication at up to 12 Mbps, the second interface supports PROFIBUS DP master/slave operation, and the third provides PROFINET Ethernet connectivity with an integrated two-port switch.

The CPU requires a Siemens Micro Memory Card (MMC) and is engineered using compatible STEP 7 software and the S7 Distributed Safety package.
