The 6AG1315-2EH13-2AB0 is a S7-300 CPU from the 6AG series, carrying an FM 8 designation. That FM 8 identifies the firmware version or function module level, which matters for software compatibility with Siemens STEP 7 V5.4 SP2 or higher. It supports CFC, FBD, LAD, SCL, STL, GRAPH, and HiGraph® — covering essentially every Siemens PLC programming language. That gives the integrator flexibility in writing control logic without worrying about language lock-in. The I2t rating of 1 A²·s defines the CPU’s short-circuit withstand; site engineers use that for selectivity coordination with the upstream breaker. Integrated PROFINET interface handles TCP/IP and UDP communication, and can act as IO controller or device. No MPI support; legacy PROFIBUS networks require a separate CP module.

Frequently asked questions
Does this CPU support CFC?
Yes, it supports CFC (Continuous Function Chart) as well as FBD, LAD, SCL, STL, GRAPH, and HiGraph®.
Will the 6AG1315-2EH13-2AB0 drop into a panel designed for the 6ES7314-1AF10-0AB0?
Mechanically both are S7-300 compact CPUs, so they share the same mounting footprint and backplane connector. However, the 6AG variant is a ruggedized version; ensure the environmental ratings match your panel design.
What is the I2t rating and why does it matter?
The I2t rating is 1 A²·s, which is the short-circuit withstand capacity. It helps select an appropriate upstream circuit breaker for selectivity.
