Overview Manuals Specifications Applications Monitoring & Control Operating Environment

Features:

  • Integrated PROFINET IRT with 2-Port Switch
  • Dual-Role Communication (Controller & Device)
  • Comprehensive On-Board Diagnostics with Web Server
The Siemens 6ES7317-2EK14-0AB0 eliminates the need for an external switch in linear network topologies. Its integrated 2-port switch supports Isochronous Real-Time (IRT) for deterministic motion control applications (e.g., printing, packaging), achieving update times as low as 250 µs. The "High Performance" option supports up to 64 IO devices in line topology, reducing hardware costs while maintaining jitter-free synchronization.

Unlike standard PLCs that act only as a master, the Siemens 6ES7317-2EK14-0AB0 can simultaneously function as a PROFINET IO Controller (managing remote I/O) and a PROFINET IO Device (being managed by a higher-level SCADA or another PLC). This is critical for hierarchical production architectures (e.g., cell control under a line PLC) and enables easy data exchange without complex programming.

Troubleshooting machine downtime is faster with the Siemens 6ES7317-2EK14-0AB0. The integrated web server allows maintenance staff to view diagnostic buffers (500 entries), tag statuses, and module states via any standard web browser without installing specialized software. The CPU also supports 10 forcing variables online, enabling rapid commissioning and loop checks.

The 6ES7317-2EK14-0AB0 Siemens SIMATIC S7-300 CPU 317-2 PN/DP Central Processing Unit may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Mid-to-Large Process Cells: Ideal for chemical batching or pharmaceutical mixing where the Siemens 6ES7317-2EK14-0AB0 manages dozens of analog loops and recipes via its 1 MB memory.
  • High-Speed Packaging Lines: Utilizes the PROFINET IRT interface to synchronize servo drives and high-speed cameras for cut-to-length or labeling machines, achieving µs-level determinism.
  • Water/Wastewater Treatment Plants: Acts as a central controller for pump stations and filtration units, leveraging the MPI/DP interface to communicate with legacy ET200 I/O while using PROFINET for SCADA uplink.
  • Material Handling (Warehouse Automation): Controls conveyor sortation systems where the integrated 2-port switch allows a daisy-chain topology, reducing network switch hardware costs across long distances.
  • Integrated Web-Based Diagnostics: Provides real-time CPU status, buffer analysis, and variable monitoring via any standard browser (Chrome/Edge) without needing STEP 7, reducing mean time to repair (MTTR).
  • Programmable Alarm System: Supports up to 300 simultaneously active Alarm S blocks, allowing detailed process alarms (high-high temperature, pump failure) with time stamps and associated values.
  • Real-Time Forcing: Offers 10 online forcing variables for inputs/outputs, enabling engineers to override field signals during dry testing or commissioning without rewiring the marshalling cabinet.
  • Cyclic Interrupts: Features 4 cyclic interrupt OBs (OB32-35), allowing time-driven tasks (e.g., PID control loops every 10ms) independent of the main scan cycle, ensuring consistent regulation.
  • Wide Temperature Range: Certified for 0°C to 60°C ambient operation, suitable for un-airconditioned electrical rooms or sheltered outdoor kiosks (with solar radiation shielding).
  • Humidity & Vibration: Designed for 5% to 95% relative humidity (non-condensing) and meets vibration standards for industrial machinery (IEC 60068-2-6), ensuring reliability on packaging lines with high-frequency shakers.
  • Electrical Immunity: Built to withstand electromagnetic interference typical of heavy inverter loads (e.g., VFDs for cranes or extruders), with a 2A recommended external power line protection.
  • Maintenance-Free Backup: The real-time clock (RTC) is backed for 6 weeks without battery via a supercapacitor. Program and data are stored permanently on the MMC card (10+ years), eliminating battery replacement hazards in critical processes.

Technical notes
When evaluating the Siemens 6ES7317-2EK14-0AB0, engineers must note that the working memory is non-expandable; thus, program optimization is required for very large applications. The CPU supports isochronous mode but only on one interface at a time (either PROFIBUS DP or PROFINET IO, not simultaneously). Furthermore, advanced S7 communication as a client requires loadable FBs on the integrated PROFINET interface. Always verify the firmware version for full feature support, including the PROFIenergy profile and Shared Device functionality.
