With ABB AFS660 switches, which support the new IEC-standard redundancy protocols (PRP, HSR), networks can now be built for
the first time with genuinely uninterrupted data communication.

• Switchover times of 0 ms guarantee high reliability of substation communication networks and systems (PRP/HSR)
• Extensive security functions guarantee all-round protection against networkborne attacks and operator errors
• Precise synchronization enables applications to comply with stringent real-time requirements

The new AFS660 switches from ABB, with robust hardware and a powerful operating system, are able to withstand extremely harsh environmental conditions. For the first time, the integration of new redundancy protocols allows uninterrupted data communication. These new techniques, PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy), are based on the international IEC62439 standard and therefore guarantee future security and interoperability. Precision time synchronization in accordance with IEEE 1588v2, synchronizes sensors, drives and measuring equipment. Gigabit Ethernet provides for a fast connection to the backbone, while connections to terminal equipment use 100 BASE-TX – either alone or in combination with 100 BASE-FX.

Applications
The AFS660 switches from ABB are optimized for the type of data communication used in the electricity supply industry, because using Ethernet to link the field-level transformer stations of a power supply grid calls for special network equipment which can guarantee uninterrupted communication in the systems under even the harshest conditions. This is the only way of ensuring that end customers receive an uninterrupted power supply.

The AFS660 switches can also be used in many other areas. They offer optimum solutions wherever uninterrupted data communication is of the essence, for example in mechanical engineering, production or security applications.

Benefits
The AFS660 switches are the first to allow uninterrupted data communication, thus ensuring continuous access to machines and systems, greatly increasing their productivity and hence also their profitability. The switches feature comprehensive security functions to provide all-round protection against network attacks. Since they also support precise synchronization, they can be used for applications with stringent real-time requirements.
