A compact S7-300 central processing unit that combines automation processing, integrated digital and analog I/O, technology functions and PROFIBUS DP communication in one controller.
The Siemens 6ES7314-6CF02-0AB0 is a SIMATIC S7-300 CPU 314C-2 DP compact CPU. Its integrated I/O provides 24 digital inputs, 16 digital outputs, four analog inputs, two analog outputs and one Pt100 input. Four high-speed counters support frequencies up to 60 kHz, while the integrated DP interface supports connection to PROFIBUS networks.
The unit uses 64 KB of working memory and an integrated 24 V DC power supply. A SIMATIC Micro Memory Card is required. Procurement should be based on the complete order code because later CPU 314C-2 DP revisions have different memory, firmware and engineering requirements.

Suitable for S7-300 projects that need CPU processing and local digital or analog I/O in a compact footprint.
The integrated DP interface supports connection to compatible distributed I/O, drives and other PROFIBUS devices.
High-speed counter channels support counting and measurement functions in packaging, conveyor and process-skid applications.
Siemens lists 6ES7314-6CF02-0AB0 as PM500: Discontinued Product or end of PLM & Support, with the end of product lifecycle since 2013-10-01. Siemens identifies 6ES7314-6CH04-0AB0 as the successor. A successor is not an automatic drop-in replacement; hardware configuration, firmware, memory and STEP 7 compatibility must be checked.
It is a SIMATIC S7-300 CPU 314C-2 DP compact CPU with integrated I/O, MPI and PROFIBUS DP communication.
The 6ES7314-6CF02-0AB0 revision has 64 KB of work memory.
It provides 24 digital inputs, 16 digital outputs, four analog inputs, two analog outputs and one Pt100 input.
Yes. Siemens specifies that a SIMATIC Micro Memory Card is required.
No. Confirm the STEP 7 project, firmware, memory, hardware configuration, wiring and PROFIBUS settings before replacement.

The complete MLFB is the starting point for every request. For 6ES7314-6CF02-0AB0, our review distinguishes this 64 KB CPU 314C-2 DP revision from earlier and later variants that carry different firmware, memory and engineering requirements.
Customers can provide a cabinet list, existing CPU label, STEP 7 project details and PROFIBUS role. This information helps focus the compatibility review before dispatch and reduces the risk of receiving a similar-looking but unsuitable revision.
Before shipment, the available unit can be checked against the requested model, visible identification, enclosure condition, connector areas and included accessories. Photo evidence can be arranged so the purchasing and engineering teams have a shared record of what is being prepared.
Packing is selected for sensitive industrial electronics, with protection for front-panel controls, connectors and exposed edges. Each shipment is organized around the confirmed quantity and destination to support clear receiving and internal handover.
The same order code is carried through availability review, quotation, packing confirmation and shipping coordination. Buyers receive a concise record of the requested model, quantity and destination rather than a generic series-level response.
For international projects, the team can coordinate commercial documentation, shipment planning and tracking details. Warranty terms are confirmed with the quotation so scope and conditions are understood before the order proceeds.
Full model and suffix verification helps prevent confusion between CPU 314C-2 DP hardware revisions.
Available condition and label photos support internal approval and receiving checks.
Project, firmware, memory card, connector and PROFIBUS details are reviewed around the actual application.
Quotation, documentation, packing and shipment communication remain aligned to the confirmed request.
| Step | Focus | What to send or confirm |
|---|---|---|
| 1 | Request definition | 6ES7314-6CF02-0AB0, quantity, destination and required delivery window. |
| 2 | Technical check | Current CPU label, firmware, STEP 7 version, MMC, connectors and PROFIBUS configuration. |
| 3 | Evidence review | Visible identification, condition, interface area and available accessories. |
| 4 | Shipment coordination | Packing, commercial documents, tracking and warranty confirmation. |
Send the exact order code, quantity, destination and a photo of the installed CPU for an availability and compatibility review.
