International Forecourt Standards Forum
Encyclopedia
The International Forecourt Standards Forum is a UK-based European organisation which designs standards for connecting devices on a service station

Standards are only available to paid members of the IFSF organisation.

Impact and Deployment

IFSF forecourt equipment has seen considerable success in Europe
Europe
Europe is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally 'divided' from Asia to its east by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways connecting...

Eastern Europe
Eastern Europe is the eastern part of Europe. The term has widely disparate geopolitical, geographical, cultural and socioeconomic readings, which makes it highly context-dependent and even volatile, and there are "almost as many definitions of Eastern Europe as there are scholars of the region"...

 technologies, are being used more widely.

Where IFSF is not used, a large variety of proprietary protocols are used. In many deployments, existing site equipment is converted to IFSF operation using a "protocol converter" or PCD, a small computer that accepts IFSF protocol and communicates to the device using its native, proprietary protocol. The PCD is most commonly fitted inside each dispenser, although it is possible for a single converter to convert many devices.

How IFSF works

IFSF is more complex but more comprehensive than most proprietary protocols. The IFSF protocol has two independent layers; a single common device application protocol layer and, multiple (currently 2: Lonworks and TCP/IP) communications protocol layers. The application protocol is independent of the underlying communications layer. The communications protocol specification makes the link to the transport layer. Historically Lonworks has been predominatly deployed because existing cables and cabling topology can be reused. TCP/IP requires higher specification cable and a point to point topology and is more suited to green field or rebuild service stations.

The IFSF standards define messages sent and received by each type of device. The messages are sent predominantly over the control network LonWorks

Within data communication protocols, optional information may be encoded as a type-length-value or TLV element inside of the protocol. TLV is also known as tag-length value....

. The messages are grouped into various "databases" for the logical parts of each device, such as a nozzle at a pump. Although methods for using TCP/IP transport have been defined this is quite rare.
