Overview Manuals CPU Identity Integrated I/O Recovery Scope Applications

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.

Apter Power can help confirm the Siemens 6ES7314-6CH04-0AB0 SIMATIC S7-300 CPU 314C-2 DP, memory card and connector scope before quotation.

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.
Description
6ES7314-6CH04-0AB0 is a compact S7-300 CPU that combines 192 KB of work memory with integrated digital and analog I/O, a Pt100 channel and high-speed counters. Its communication identity is CPU 314C-2 DP, using MPI and an integrated PROFIBUS DP interface rather than PROFINET.

A replacement 6ES7314-6CH04-0AB0 still requires the two 40-pole front connectors and a Micro Memory Card. Siemens has placed the product in phase-out, so program backup, memory-card condition and connector scope should be resolved before the installed controller is disturbed.

Technical notes
6ES7314-6CH04-0AB0 is the CPU 314C-2 DP version with MPI and integrated PROFIBUS DP; it is not the PN/DP model. The two 40-pole front connectors and Micro Memory Card are required separately. Preserve the STEP 7 project, hardware configuration, memory card and I/O wiring before exchanging the phased-out CPU.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
A replacement project needs PROFINET. Does 6ES7314-6CH04-0AB0 provide the PN/DP interface found on similar CPU 314C models?
No. This complete order code is CPU 314C-2 DP with MPI and integrated PROFIBUS DP. A PN/DP requirement points to a different hardware variant.
Can 6ES7314-6CH04-0AB0 start without the existing Micro Memory Card?
The Siemens product description requires a Micro Memory Card. Stage the correct card and verified project backup before replacing the CPU rather than assuming internal memory will restore the application.
The offer for 6ES7314-6CH04-0AB0 excludes front connectors. Can the installed wiring still be reused?
Possibly, if both 40-pole connectors are the correct type, undamaged and fully labeled. Their reuse should be stated explicitly because they are required but not automatically included.
After changing 6ES7314-6CH04-0AB0, the CPU runs but a PROFIBUS segment is offline. What should be compared first?
Compare the loaded hardware configuration, DP address, bus connector and termination with the saved project. CPU RUN state does not prove that the integrated DP interface matches the former network.
One integrated analog value is wrong on 6ES7314-6CH04-0AB0 while logic and digital I/O are normal. Is a full CPU exchange justified?
Not yet. Check the channel configuration, range, terminal assignment and field signal first; the integrated functions share a housing but can still have distinct wiring or configuration faults.
Siemens lists 6ES7314-6CH04-0AB0 in phase-out. What should a maintenance order include beyond the CPU?
Include the Micro Memory Card plan, connector scope, verified STEP 7 backup and PROFIBUS settings. These recovery items often determine whether the phased-out spare can return the machine to service.
