Product details

End-of-Life Sourcing Reality

The 6ES7315-2AF03-0AB0: No direct official replacement is listed in the lifecycle record. Any functional substitute would require a full engineering review of the S7-300 slot, backplane power budget, and software porting. For an exact drop-in, this specific order code is the only match.

FM 8 Expansion & CFC Support

CFC (Continuous Function Chart) is supported, allowing graphical interconnection of blocks for process control. Combined with the full command set (binary logic, floating-point arithmetic, jump functions), this CPU suits complex automation tasks requiring sequential and continuous control.

Frequently asked questions

How many function modules does this CPU support?

Up to 8 function modules (FM 8). This allows expansion with specialized modules like counters or positioning drives on the same rack.

What is the power consumption and supply voltage?

Typical power draw is 8 W at 24 V DC. This must be factored into the backplane PSU budget.

Which engineering software is required to program this CPU?

STEP 7 V5.0 is required. The CPU supports LAD, FBD, STL, SCL, GRAPH, CFC, and HiGraph® programming languages.
