Product details

What this module is

The Siemens 6AG1315-6FF04-2AY0 is a S7-300 CPU module (type SFB) with integrated safety (PROFIsafe) and railway/ATEX certifications. It supports LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC programming languages. Rated for -40 to 70 °C ambient, with dimensions 40 mm width, 125 mm height, 130 mm depth. Process image: 244 bytes input / 244 bytes output.

FM 8 is a firmware/module identifier; verify compatibility with STEP 7 V5.2 SP1 or higher (HW update required). CFC (Continuous Function Chart) is supported, enabling graphical block-diagram engineering alongside LAD/FBD/STL/SCL. I²t rated at 1 A²·s — this is the thermal withstand of the internal power supply input; coordinate upstream protection accordingly. PROFIsafe allows the module to act as a safety controller with failsafe communication over PROFIBUS/PROFINET.

Compliance and environment

Certified for EN 50155 (railway, sections 4,5,12, T1, Category 1, Class A/B:2007) and ATEX for explosive atmospheres. CE marked.

Frequently asked questions

Does this module support CFC (Continuous Function Chart)?

Yes, CFC is supported, along with LAD, FBD, STL, SCL, GRAPH, and HiGraph.

What compliance certifications does it carry?

It carries CE mark, ATEX certification for explosive atmospheres, and EN 50155 railway approval (sections 4, 5, 12; T1, Category 1, Class A/B:2007).

What is the I²t rating and why does it matter?

The I²t rating is 1 A²·s, indicating the thermal energy withstand capability of the power supply input. This affects selection of upstream overcurrent protection and coordination.
