Product details

CPU 318-3FL01-0AB0 — SFB with PROFIsafe and IRT

The Siemens 6ES7318-3FL01-0AB0 is a SIMATIC S7-300 CPU 318 SFB (Safety Fault-Proof) unit designed for fail-safe automation. It carries FM 8 (8 function blocks) and supports CFC, FBD, LAD, SCL, STL, GRAPH, and HiGraph programming, all under STEP 7 V5.5 or higher. The integrated PROFINET interface enables IRT (isochronous real-time) communication — critical for synchronized motion axes — and UDP/TCP/IP with loadable function blocks. PROFIsafe is supported natively, meaning this CPU can run safety programs (up to SIL 3) over the same PROFINET cable as standard control, without a separate safety bus.

I/O capacity and communication

The CPU handles 244 bytes of process input and 244 bytes of output data, with a maximum of 32 modules overall. It includes 4 counters (preset 10) and supports forcing, retentive memory (must be restarted at each restart), and routing. Communication interfaces include RS 485, PROFINET (client/server), and up to 4 CP connections for LAN, 10 for PtP, and 8 for additional PROFIBUS via CP. No MPI or DPV1 is available — plan your network topology accordingly. The GSD file is available from Siemens for PROFIBUS integration.

Physical and environmental

Dimensions are 120 mm wide × 125 mm high × 130 mm deep. Operating temperature range is 0 °C to 60 °C. The I2t rating is 1.2 A²·s, and the CPU is isolated.

Frequently asked questions

Where can I buy 6ES7318-3FL01-0AB0 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is 6ES7318-3FL01-0AB0's listed FM (8) on this component line?

FM 8 means the CPU supports 8 function blocks in its fail-safe program structure, used for safety-related logic such as emergency stops, light curtains, and two-hand controls.

What is 6ES7318-3FL01-0AB0's listed CFC (Yes) on this component line?

CFC (Continuous Function Chart) support means you can program the CPU graphically by connecting function blocks, rather than writing ladder or statement list code — useful for process-oriented logic.

What compliance documentation does this brand provide for 6ES7318-3FL01-0AB0 (RoHS, REACH, UL, IEC)?

The evidence does not list specific compliance documentation for this order code. Siemens typically provides RoHS, REACH, and CE declarations for SIMATIC S7-300 CPUs — request the declaration of conformity from your distributor if required for your project.
