4. Setup and Installation
Follow these steps for proper installation of the CPU:
- Mounting: Securely mount the CPU onto a standard DIN rail within a control cabinet. Ensure adequate ventilation space around the unit.
- Power Connection: Connect the appropriate power supply to the CPU's power terminals. Refer to the technical specifications for voltage requirements. Ensure power is off before connecting.
- Module Installation: Insert any required interface modules or expansion modules into their designated slots on the CPU or adjacent to it.
- PROFIBUS DP Connection: Connect the PROFIBUS DP cable to the DP interface port on the CPU. Ensure proper termination of the PROFIBUS network.
- Programming Device Connection: Connect your programming device (e.g., PC with STEP 7 software) to the CPU's programming port (typically MPI or Ethernet, depending on the specific CPU variant and adapter).
- Initial Power-Up: After all connections are secure, apply power to the CPU. Observe the status LEDs for proper boot-up.
5. Operating Instructions
The S7-300 CPU 315-2DP operates under the control of a user-programmed logic. Basic operation involves:
- Programming: Use Siemens STEP 7 software to create, download, and manage your automation program.
- Operating Modes: The CPU typically has RUN, STOP, and MRES (Memory Reset) modes. These are usually controlled via a mode switch on the front panel or through software.
- RUN: The CPU executes the loaded program.
- STOP: The CPU halts program execution.
- MRES: Resets the CPU's memory (use with caution, as it deletes the program).
- Monitoring: Monitor the CPU's status and program execution using the diagnostic functions within STEP 7. Observe the LED indicators on the CPU for quick status checks.
- Communication: The integrated PROFIBUS DP interface allows communication with distributed I/O devices and other PROFIBUS-enabled components.
6. Maintenance
Regular maintenance ensures the longevity and reliable operation of your CPU:
- Cleaning: Periodically clean the exterior of the CPU and surrounding area to prevent dust accumulation, which can hinder cooling. Use a soft, dry cloth. Do not use liquid cleaners.
- Environmental Checks: Ensure the operating environment remains within specified temperature and humidity ranges.
- Connection Integrity: Periodically check all cable connections for tightness and signs of wear or corrosion.
- Firmware Updates: Refer to the manufacturer's website for any available firmware updates and follow their instructions for installation.
7. Troubleshooting
This section provides solutions to common issues. For more complex problems, consult the detailed Siemens S7-300 documentation or contact technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| CPU not powering on | No power supply; incorrect wiring; faulty power supply unit. | Check power connections; verify power supply output; replace power supply if necessary. |
| SF (System Fault) LED is on | Hardware fault; configuration error; programming error. | Check diagnostic buffer in STEP 7; verify hardware configuration; review program logic. |
| BF (Bus Fault) LED is on | PROFIBUS communication error; incorrect bus termination; faulty cable. | Check PROFIBUS cable connections; verify bus termination resistors; inspect cables for damage. |
| CPU not going into RUN mode | Program error; CPU in STOP mode; memory error. | Check program for errors; ensure mode switch is in RUN; perform a memory reset if necessary (MRES). |
