Overview
SIEMENS SIMATIC S7-300
6ES7317-2EK14-0AB0 CPU 317-2 PN/DP
A high-performance S7-300 central processing unit with integrated MPI/PROFIBUS DP and two-port PROFINET connectivity for distributed automation.
At a Glance
| Brand | Siemens |
|---|---|
| Model | 6ES7317-2EK14-0AB0 |
| Product Type | CPU 317-2 PN/DP |
| Core Function | Central control with PROFIBUS and PROFINET communication |
| Application or Compatible Series | SIMATIC S7-300 automation systems |
Engineering Fit
Suitable for medium to large S7-300 applications that need fast program execution and integrated communication with distributed I/O.
Replacement Focus
Match the exact article number, STEP 7 version, Micro Memory Card, rack configuration and all station addresses.
Product Overview
This central processing unit combines 1 MB of integrated work memory with fast instruction processing and extensive S7-300 addressing resources. The built-in interfaces support legacy fieldbus devices and PROFINET-based distributed I/O.
A two-port Ethernet switch supports line topologies, while the MPI/PROFIBUS interface provides continuity for existing S7 networks. The installed project and network identity must be restored accurately after replacement.
Key Functions
Fast Program Execution
Processes bit, word, fixed-point and floating-point instructions for demanding cyclic control tasks.
Dual-Network Integration
Combines MPI/PROFIBUS DP with a two-port PROFINET interface in one CPU.
Distributed I/O Control
Operates as a PROFINET IO controller for connected devices and supports PROFIBUS DP automation networks.
Scalable S7-300 Configuration
Supports a central rack and expansion racks within the documented S7-300 configuration limits.

Frequently Asked Questions
How should I migrate the network configuration when replacing 6ES7317-2EK14-0AB0?
Restore the configured MPI or PROFIBUS address, PROFINET device name, IP settings and topology from the verified project backup.
Does 6ES7317-2EK14-0AB0 require a memory card to operate?
Yes. Install a compatible SIMATIC Micro Memory Card containing the correct project, with capacity up to 8 MB.
Can 6ES7317-2EK14-0AB0 control PROFINET distributed I/O directly?
Yes. The integrated Ethernet interface supports operation as a PROFINET IO controller.
How many PROFINET devices can 6ES7317-2EK14-0AB0 manage?
The documented maximum is 128 IO devices, subject to the complete project configuration and performance requirements.
Can 6ES7317-2EK14-0AB0 be used in an expanded S7-300 rack system?
Yes. It supports one central rack and up to three expansion racks, with up to eight modules per rack.
Which engineering software is appropriate for 6ES7317-2EK14-0AB0?
Use STEP 7 V5.5 or a supported later engineering environment that matches the installed firmware and project.
What should I check if 6ES7317-2EK14-0AB0 does not reconnect to PROFINET devices?
Verify the device name, IP configuration, port topology, cabling and the IO device assignments in the downloaded project.
Compatibility & Ordering Notes
Compatibility Checks
- Match the central and expansion rack arrangement.
- Verify the PROFINET device name and IP configuration.
- Confirm all MPI and PROFIBUS node addresses.
- Use a verified backup of the hardware configuration and user program.
