Valve islands for highly available PROFINET environments

Machinery and systems must be designed in such a way that neither humans nor the environment or property are damaged by their functions. Typically, such requirements – especially in new systems – are resolved using a PROFIsafe controller, the PROFIsafe protocol and respective fail-safe IO modules.

Therefore, the fluidics expert Bürkert Fluid Control Systems and Siemens have been constantly pooling their know-how: For example, the AirLINE SP Type 8647 valve island can now be integrated into the distributed peripheral systems SIMATIC ET 200SP and ET 200SP HA. The new integration stage further increases system availability and reliability.

For the first time, valve islands in highly available and up to R1 redundant PROFINET environments can be operated using the PROFIsafe protocol directly in a distributed peripheral system. Pneumatic segments or individual valves can then be switched off selectively via the corresponding safety relay.
