  • Motion control and positioning tasks
  • Replacement for older S7-300 CPUs (e.g., 317-2DP, 317-2PN/DP earlier versions)
  • Complex multi-axis motion control systems

Lifecycle

Lifecycle status: Phase-out product. SIMATIC S7-300 system families generally available until 2023, with spare parts support for approximately ten years thereafter.

Active for spare parts: Expected to remain available through at least 2035+.

Compatible successor (drop-in replacement): 6ES7317-2EK13-0AB0 (previous version). When replacing with 6ES7317-2EK14-0AB0, the STEP 7 project does not need to be changed. Use the previous type's order number in hardware configuration.

Long-term migration path (S7-1500): 6ES7517-3AP00-0AB0 (S7-1500) is the recommended successor platform.

Migration requirements: Program must be ported to TIA Portal; hardware modules replaced with S7-1500 compatible components; not a plug-and-play replacement across platform boundaries. Full hardware and software re-engineering is required for S7-1500 migration.

Frequently Asked Questions
Is 6ES7317-2EK14-0AB0 discontinued? What is its availability?
The SIMATIC S7-300 system family was generally available until 2023. Following the phase-out declaration, products are available as spare parts for approximately ten more years. This CPU is expected to remain available through at least 2035+ as a spare part.
What is the compatible drop-in replacement for this CPU?
The previous version is 6ES7317-2EK13-0AB0. When replacing with 6ES7317-2EK14-0AB0, the STEP 7 project does not need to be changed. You can configure the previous type's order number in hardware configuration.
What is the long-term migration path to S7-1500?
The recommended S7-1500 replacement is 6ES7517-3AP00-0AB0. This is not a plug-and-play replacement; full hardware and software re-engineering is required, including program porting to TIA Portal and new hardware installation.
Which programming software is supported?
Requires STEP 7 V5.5 or higher. With appropriate HSP files, earlier versions down to V5.4 SP4 may work. The CPU cannot be operated with versions below V5.4 SP4.
Can this CPU be used for software redundancy?
Yes, the 6ES7317-2EK14-0AB0 can be used for software redundancy applications. Two CPUs and CP342-5 communication processors are typically used for this purpose.
