Description
The Siemens 6ES7317-2AK14-0AB0 is the CPU 317-2 DP. Siemens's data sheet gives 1 MB of integrated work memory, a Micro Memory Card for the program, a combined MPI/PROFIBUS DP interface and a second PROFIBUS DP interface, each at up to 12 Mbit/s, two integrated DP masters with up to 124 DP devices each, and a 24 V DC supply. Siemens's data sheet marks it as a spare part. Siemens names no direct successor for the order number; its route forward is migration to the S7-1500 with ET 200MP.
Application: PLC controller
Used with: SIMATIC S7-300 rack (S7-300 backplane bus)
What is the 6ES7317-2AK14-0AB0 used for?
It is the controller of an S7-300 station: it runs the STEP 7 program and drives the I/O modules on its rack and the remote I/O on its networks. A failed CPU stops the machine or line it controls. The 317-2 DP suits larger programs with I/O spread over two PROFIBUS DP lines.
Key features
- 1 MB (1,024 KB) integrated work memory
- 1st interface MPI/PROFIBUS DP, 2nd interface PROFIBUS DP, 12 Mbit/s
- Up to 124 DP devices per DP master
- 24 V DC supply
- Discontinued by Siemens on 1 October 2025; spare part only

Product Questions
Is the 6ES7317-2AK14-0AB0 discontinued?
Yes. Its manufacturer lifecycle status is Discontinued.
Can another Siemens SIMATIC S7-300 part replace it?
Potential replacements must be checked against the required ratings, dimensions and connections. Sharing a family name does not establish interchangeability.
Do you ship worldwide?
Yes. TimControls ships worldwide. Parts usually ship within 3 to 7 working days of order confirmation, and the exact lead time and shipping options are stated on your quote. Include your delivery country and postal code when you ask for a quote.
