FAQ

What is the significance of the "F" in "F-AI" for this module?
The "F" stands for Fail-safe. This module is part of the Siemens Safety Integrated portfolio and is designed for safety-related applications up to SIL 3 (IEC 61508) and PL e (ISO 13849). It has internal diagnostics and redundancy to ensure a safe state in case of a fault.

Can this module be used in a standard S7-300 rack, or only in an ET 200M station?
The SM 336 F-AI module can be used in both a central S7-300 automation system (with a fail-safe CPU like a CPU 315F) and a distributed I/O station like the ET 200M (with an IM153-2 HF interface module or similar). Its functionality is consistent across both platforms.

What version of STEP 7 or TIA Portal is required to configure this module?
To configure this module, you typically need STEP 7 V5.5 or higher with the S7 Distributed Safety V5.4 SP5 library. For use in TIA Portal, you would need TIA Portal V12 or higher with the corresponding safety package (e.g., STEP 7 Safety Advanced). Always check the exact hardware support package (HSP) requirements for your software version.
