Siemens S7-300 6ES7 317-2FK14-0AB0 CPU317F-2 PN/DP

The SIEMENS SIMATIC S7-300 CPU 317F-2 PN/DP (6ES7 317-2FK14-0AB0) is the failsafe version of the high-performance 317-series controller. It is specifically designed for plants with high-end safety requirements (Safety Integrated) alongside standard automation tasks.

Safety Integrated Features:

Fail-safe Communication: It uses the PROFIsafe profile for safety-related communication via both PROFINET and PROFIBUS DP.
Redundancy: The safety program uses internal self-tests and diverse logic processing to ensure that if a hardware or software fault occurs.
Software: Requires STEP 7 Safety Advanced (for TIA Portal) or Distributed Safety (for STEP 7 Classic) to program the failsafe.

Common Maintenance:

MMC Handling: Never remove the Micro Memory Card (MMC) while the CPU is powered on. This can corrupt the safety program and trigger a “STOP” mode.
Firmware Updates: Ensure the CPU is running the latest firmware (V3.2.x) to maintain compatibility with newer PROFINET devices.
