2 TwinSAFE Integration of Functional Safety

3 From Safety Relais Logic

4 From Safety Relais Logic to Modern Safety Concepts

5 Advantages of Safetybus systems Fast reaction applicable for high dynamic drive architecture Simplified System better clarity simple cabling simple extension of the system better diagnosis and therefore: higher safety Pre-tested safety functions within the devices according to the legal standards Lower costs

6 Safe data exchange Safe input Safe Output Copying data in TwinCAT Safe Drive Safe Logic Communication must be finished within the watchdog time
