Burkert valve island model 8652 with PROFINET system

Bürkert's 8652 valve island now supports S2-level redundancy based on PROFINET communication. Today, we'll delve into its advantages. The new 8652 Burkert valve island redundancy system with PROFINET is a fault-tolerant hot backup measure in high-risk process industries or infrastructure.

It allows: In the event of a primary system failure, the hot-backup slave system can immediately and seamlessly take over the control tasks of the original system and downstream equipment.

It ensures reliable and continuous safe production even when some process equipment and facilities fail; This effectively manages downtime caused by equipment/environmental anomalies, enhancing reliability and reducing safety risks.

Therefore, industries and fields assessed as high-risk, such as pharmaceuticals, chemicals, and aerospace, all have such special control redundancy requirements. in higher system availability.

If equipment, facilities, or control systems fail, companies will suffer huge economic losses due to equipment downtime and production delays. Therefore, in addition to MRP (Media Redundancy Protocol), the German Burkert 8652 valve island now also features PROFINET-based S2 redundancy control.

The combination of PROFINET S2 redundancy and MRP solves two key problems: single-link communication interruption (left) and master-slave hot standby switching in redundant dual control systems (right).

The Media Redundancy Protocol (MRP) prevents downstream equipment from losing communication and control due to a technical failure in a single communication link.

We look forward to your joining us, growing together, and creating a better future. We promise to provide you with a fair, just, and harmonious working environment, allowing you to enjoy your work while showcasing your talents.

If the communication connection of the 8652 is interrupted (eg, due to a line break), the valve island will switch to the backup communication link, and data will continue on the backup link, thus preventing communication failures at the field or equipment level due to communication link interruptions.

However, if the programmable logic controller (PLC) fails, this function cannot prevent downtime and loss of control. 03. PROFINET system redundancy S2 prevents overall system failure in the event of a technical malfunction in system control. We look forward to your joining us, growing together, and creating a better future.

We promise to provide you with a fair, just, and harmonious working environment, allowing you to utilize your talents while enjoying your work. Through two PROFINET interfaces, the 8652 Burkert valve island can now be connected to both master and slave systems simultaneously and receive control.

If the master PLC fails or requires maintenance, the second backup PLC and its connected PROFINET network will maintain uninterrupted data exchange. Thus, through an architecture of redundant PLCs, redundant communication, and redundant remote substations, system availability is ensured at the control level.

Redundant systems effectively reduce the risks of equipment failure to production processes, eliminating the significant and safety risks caused by unpredictable downtime. Advantages ➤ Based on MRP and PROFINET S2 redundancy, higher process reliability and system availability can be achieved.

➤ In the event of failure of the master controller and master link, seamless switching losses to the slave controller and slave link can be achieved, ensuring continuous production. Additionally, the new Burkert valve manifold 8652 with PROFINET system is a testament to its focus and professionalism.

The Burkert valve manifold 8652 has also obtained the PROFINET S2 redundancy certificate issued by the international PI organization. The S2 testing was conducted and completed by Siemens Germany - Automation and Drives Group.
