Features:
- Compact CPU and I/O: Processing, mixed integrated signals and high-speed counters share one S7-300 module.
- PROFIBUS DP identity: The second communication role is DP, not the PROFINET interface used by a different CPU variant.
- Memory-card dependency: The required Micro Memory Card remains part of the controller recovery path.
6ES7314-6CH04-0AB0 is the S7-300 CPU 314C-2 DP with 192 KB work memory.
Its integrated I/O and counters reduce separate module count, but they also make wiring and program recovery part of the same replacement event.
The DP suffix, memory card and two front connectors are the fastest ways to separate this CPU from similar 314C variants.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- 314C-2 DP platform: The CPU combines compact control with integrated PROFIBUS DP communication.
- MPI engineering path: The MPI interface remains available for the documented S7-300 communication and service tasks.
- No PROFINET port: PN/DP functions belong to another order code and must not be inferred here.
- 192 KB work memory: Program fit is checked against the exact project rather than a family name alone.
- Digital channels: Twenty-four inputs and sixteen outputs are part of the CPU hardware.
- Analog channels: Four inputs, two outputs and one Pt100 path require preserved terminal assignments.
- High-speed counters: Four channels support pulse tasks up to the documented frequency.
- Single replacement boundary: A CPU exchange can affect logic, communications and integrated field circuits together.
- Micro Memory Card: The required card and its valid project content are confirmed before power-up.
- Front connectors: Two 40-pole connectors must be available, reusable and correctly labeled.
- STEP 7 project: Hardware configuration and network addresses are recovered from the controlled backup.
- Commissioning order: CPU state, DP network and each integrated-I/O group are tested separately.
- Compact machine control: Combines logic and mixed I/O where a small S7-300 footprint is valuable.
- PROFIBUS cells: Acts as the CPU in systems that retain a DP network rather than PROFINET.
- Counter applications: Supports suitable pulse and speed measurement tasks through integrated high-speed counters.
- Legacy S7-300 maintenance: Restores an exact controller while a phased migration is planned independently.
