Advances in Foundation Fieldbus HSE technology

Taking a significant step to further advance Foundation Fieldbus High Speed Ethernet (HSE) technology, Smar has registered a new class of linking device: the DF51 42a2

Taking a significant step to further advance Foundation Fieldbus High Speed Ethernet (HSE) technology, Smar has registered a new class, a second generation of linking device: the DF51 42a2.

The new product is set apart from its predecessor, the 42a, by the type of specification used for implementing High Speed Ethernet (HSE) communication.

The Smar use of HSE has grown continuously over the years.

In 2000, the company installed the first commercial HSE device on Petrobras Namorado I offshore platform.

In 2001, it registered its first linking device: the DF51 42a Class.

That event opened new markets to Smar products and technology and led to the establishment of significant partnerships with major suppliers - such as Metso Automation, Endress+Hauser, and Rockwell Automation - interested in the HSE protocol.

Today, the Smar High Speed Ethernet (HSE) development has resulted in the registration of a new class of linking device: the DF51 42a2.

The 42a is based on the FF FS 1.1 final specification, while the 42a2 Class device incorporates the FF FS 1.29 final specification.

The FS 1.29 specification features a new, all-encompassing directory format for an HSE equipment net information management base, which contains data on the specification revision implemented by the equipment and the class of profile supported.

It also provides a new, more direct and automatic connection option for the equipment application directory based on either the HSE or H1 communication protocols.

Registration of the DF51 42a2 linking device is a significant step in the advancement of HSE technology, once again proving that Smar is first in Fieldbus.

The DF51 42a2 is a component of the Smar Foundation Fieldbus Process Control and Enterprise Automation solution (SYSTEM302).
