Siemens 6ES7317-2EK13-0AB0 S7-300 CPU

The Siemens 6ES7317-2EK13-0AB0 CPU 317-2 PN/DP is an advanced modular controller for the SIMATIC S7-300 platform, equipped with a combined MPI/DP port and an integrated dual-port PROFINET industrial Ethernet interface for machine and plant automation.

Key Technical Specifications

• Manufacturer: Siemens
• Part Number: 6ES7317-2EK13-0AB0
• Product Series: SIMATIC S7-300
• CPU Model: CPU 317-2 PN/DP
• Work Memory: 1 MB (1,024 KB) integrated work memory (operation requires a SIMATIC Micro Memory Card / MMC for load memory and retentive data storage, supporting up to 8 MB MMC)
• Integrated I/O: None (standard modular CPU; external S7-300 signal modules are required for digital and analog process I/O)
• Communication Interface 1 (MPI/DP): 1x RS-485 interface configurable for MPI or PROFIBUS DP master/slave communication (up to 12 Mbps)
• Communication Interface 2 (PROFINET): Integrated PROFINET interface with a 2-port switch (2x RJ45 ports). Verify the required PROFINET communication role and supported services against the official documentation for this exact CPU model.
• Isochronous Mode: Supported on PROFIBUS DP and PROFINET for time-synchronized communication
• Rack Expansion: Supports 1 central rack and up to 3 expansion racks (multi-tier configurations require IM 360/IM 361 interface modules; slot allocation governed by system configuration)
• Engineering Software Requirements: Siemens specifies STEP 7 V5.4 SP4 or higher, or STEP 7 V5.4 SP2 with hardware support package HSP 0144. Verify installed engineering software versions and project hardware configurations prior to commissioning.

Applications and System Configuration

This controller is suited for industrial automation architectures requiring direct PROFINET integration alongside traditional PROFIBUS fieldbus networks. The onboard 2-port switch enables linear network configurations without external industrial switches, while the MPI/DP port provides connectivity for programming devices, HMIs, or legacy DP subnets. Because it features no onboard I/O, all field signals must be implemented via external S7-300 modules. Verify memory allocation, IP network topology, PROFINET device names, and rack layout prior to installation.

Product Status and Sourcing Notice

The SIMATIC S7-300 platform is a mature, legacy product family from Siemens, with this model categorized as a spare part for maintenance, replacement, and system continuity. The official successor model designated by Siemens is 6ES7317-2EK14-0AB0 (which also features 1 MB work memory). Confirm the specific hardware revision, firmware release, physical condition, and MMC memory card requirements for your application prior to order confirmation. Product availability, unit condition, pricing, lead time, warranty terms, and shipping options will be confirmed individually in the quotation.
