The Siemens 6ES7315-2EH14-0AB0 is described by Siemens as: SIMATIC S7-300 CPU 315-2 PN/DP, central processing unit with 384 KB work memory, 1st interface MPI/DP 12 Mbps, 2nd interface Ethernet PROFINET, with 2-port switch, Micro Memory Card required.
S7-300 modules are among the most replaced automation spares: keeping an identical module in stock lets maintenance swap a failed card in minutes and reload or keep the existing program.
See our Siemens range.
Siemens lists this order number as a spare part, which means it is still supplied for existing installations while newer versions exist for new projects. We supply the exact order number for like-for-like replacement and can quote the current version too.

- Replacing a failed CPU, I/O or power supply module
Compatibility and replacement
Use exactly the same order number when possible, because the hardware configuration in STEP 7 or TIA Portal refers to it. Check the firmware version of a CPU on the label of the old unit; if a newer version is supplied, it can normally replace the older one, but confirm with your hardware configuration.
Replacement checklist
- Back up the program and parameters from the old device if it still runs.
- Look for signs of overvoltage, water or heat damage in the cabinet so the new part does not fail for the same reason.
- Compare the full order number 6ES7315-2EH14-0AB0 with the label on the old unit, including the last digits (they identify the version).
Frequently asked questions
Which software is used?
STEP 7 (SIMATIC Manager) or TIA Portal, depending on the version used for the existing project.
Is the memory card included with a CPU?
No. S7-300 CPUs with MMC slot need a SIMATIC Micro Memory Card, ordered separately; reuse the card from the old CPU if it is undamaged.
Can I get a datasheet?
The official manufacturer datasheet is the source of the technical data above; we can send the PDF with the quotation on request.
Do you supply larger quantities for projects?
Yes. For panel builders and plant projects we quote complete lists; send the bill of materials on WhatsApp or through the inquiry form.
How fast can you deliver, and is there a warranty?
Air shipping usually takes 5 to 7 days once the part is ready, to almost any country. Each part is new and original with a 1-year warranty. Message us on WhatsApp with the order number for a quotation.
