System position

Evidence and limits

Siemens documents this reference as a SIMATIC S7-300 CPU 314 IFM compact CPU with integrated 24 V DC supply, MPI and integrated digital and analog I/O.

Executes the S7-300 control program while its integrated I/O exchanges machine signals and the MPI interface links engineering or operator communication.

The inferred system position places this reference Sits at the center of an S7-300 station between integrated field I/O, MPI-connected devices and the STEP 7 control program.

Unknown: installation-specific compatibility, firmware and configuration support, current unit condition, and commercial availability.
