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.
