Siemens 6ES7318-3FL01-0AB0 is the SIMATIC S7-300 CPU 319F-3 PN/DP fail-safe CPU for standard and safety-related automation tasks. Siemens specifies 2.5 MB work memory, a first MPI/DP interface up to 12 Mbit/s, a second PROFIBUS DP master/slave interface and a third Ethernet PROFINET interface. A SIMATIC Micro Memory Card is required. The integrated communication paths support engineered controller, distributed I/O and network connections within an approved safety project. Siemens lists the life-cycle phase as PM400: Announcement of product phase-out since 1 October 2023; this wording must not be treated as discontinued.
Condition, availability and warranty are Stockoems commercial information, not Siemens manufacturer commitments.
Execute the approved standard and safety-related controller program.
Connect engineering or distributed automation devices through the first interface.
Operate the configured DP master or slave communication role.
Integrate Ethernet-based automation devices through the third interface.
Verify the complete 6ES7318-3FL01-0AB0 order number, safety approval, firmware, Micro Memory Card, MPI/DP and PROFIBUS settings, PROFINET device names, hardware configuration and F-project before replacement. Similar CPU 319 or 319F variants are not automatically interchangeable. Validate the safety program through the approved plant procedure.

Documented communication channel
Our workflow combines inspection planning, label verification, compatibility documentation, protective handling, logistics coordination, customs-file preparation and after-sales communication. Product identity and visible label data are compared with the order. Packaging is selected for the item and route, while tracking and shipping documents are coordinated for the destination. Specific stock quantities and delivery timing are provided only through written commercial communication.
Choose a supplier that preserves the complete model, explains condition clearly, requests label evidence and separates commercial terms from manufacturer specifications.
Request written identity, quantity, condition, warranty terms, packaging scope, shipping basis, customs documents and return authorization rules.
Provide installed labels, rack and slot records, CPU firmware, Micro Memory Card, F-project backup, PROFIBUS settings, PROFINET names and safety-validation records.
Shortened model strings, copied data from similar products, unclear condition language, unverifiable quantities, missing label evidence and absent return terms require caution.
Send the complete part number, required quantity, destination country and clear product-label photographs for documented review.
