Diagnostica reti PROFINET e sistemi Fail-Safe (TIA-DIAG-PNS)

This course provides the basic skills required for diagnosing and maintaining PROFINET communication networks and Fail‑Safe safety systems in industrial automation environments. The objective is to enable technical personnel to quickly identify the main communication issues, correctly intervene on distributed I/O devices, and restore plant operation while minimizing machine downtime. The first part of the course introduces the operating principles of a PROFINET network, with a specific focus on hardware and software diagnostic techniques. Participants will learn to use the analysis tools available in TIA Portal and dedicated applications such as PRONETA, useful for identifying configuration, communication, or wiring issues. Proper procedures for replacing SIMATIC ET200 distributed I/O devices will also be presented. The second part is dedicated to Fail‑Safe systems, including an overview of key reference standards and wiring methods between field devices and safety modules. Diagnostic techniques via module LED indicators and software tools will be illustrated, along with procedures for replacing and restoring hardware components without altering the system’s F‑Signature.

After attending the course, you will be able to:
- Quickly recognize the main anomalies that can occur in a PROFINET network
- Replace a SIMATIC ET200 distributed I/O device
- Correctly replace a safety‑related component without altering the F‑Signature

PROFINET Communication Networks
- Overview of PROFINET network operating principles
- Hardware diagnostics of a PROFINET network
- PROFINET diagnostics using TIA Portal
- PRONETA
- Replacement of SIMATIC ET200 distributed I/O devices
- Use cases on common PROFINET issues and best practices for their resolution
Fail‑Safe Systems
- Overview of applicable standards
- Wiring types between field devices (sensors, actuators) and signal modules
- Fault diagnostics via expansion module LED indicators (fault, passivation, reintegration, etc.)
- Fault diagnostics and analysis using TIA Portal
- Hardware replacement and restoration
- F‑Signature: how to manage it
Theoretical knowledge will be reinforced through practical exercises on a SIMATIC S7‑1500 Fail‑Safe automation system and a SIMATIC ET200SP distributed I/O device equipped with safety modules.
