Product details

Environmental and hardware fit

The 6AG1314-6EH04-7AB0: Dimensions are 120 mm wide, 125 mm high, and 130 mm deep — occupies one slot in the S7-300 profile rail. The 244-byte input and 244-byte process-image area matches the standard CPU 314C mapping, so you can reuse the same I/O configuration. Preset at 10 as the default runtime meter counter.

Software and engineering tools

Programmable in all standard S7-300 languages: LAD, FBD, STL, SCL, GRAPH, and CFC. Supports forcing and routing. UDP communication is available via the integrated PROFINET interface and loadable function blocks. STEP 7 V5.5 or higher is required.

Frequently asked questions

Does this CPU include a PROFINET interface?

Yes, it has an integrated PROFINET interface with IRT support for isochronous real-time communication. It also supports UDP via loadable function blocks.

What is the I²t rating?

0.7 A²·s. This is the short-time withstand rating before the internal protection clears; keep that in mind when sizing the power supply or external fusing.

Can I use the same I/O map as the standard CPU 314C?

Yes, the process-image input/output size is 244 bytes each, identical to the standard variant. Preset counter at 10 matches as well.
