Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New Exclusive -

Hybrid sites with EV chargers need to share transformer loads. A third-party energy management controller can monitor Gilbarco dispenser pulser data over two-wire to calculate power draw from submersible pumps, then throttle EV chargers accordingly.

As the industry moves toward more open-site architecture, incorporating new third-party pump controllers (Forecourt Controllers - FCC) that can communicate with existing or new Gilbarco units using this protocol is essential.

As the petroleum retail landscape evolves, the demand for flexible, cost-effective forecourt control systems has increased. Historically, integrating Third-Party Pump Controllers (PPCs) with Gilbarco dispensers required complex, proprietary hardware interfaces or the complete removal of the dispenser’s internal electronics.

The controller software must be programmed to interpret the specific timing and voltage levels associated with the Gilbarco Two-Wire standard.

The protocol follows a master-slave architecture where the console (master) initiates all communication. Only the dispenser with the matching address responds, while others on the loop ignore the data.

This is a popular third-party universal controller. The PTS Controller Technical Guide details how to bridge third-party systems to Gilbarco dispensers.

Devices like the Gilbarco 2-Wire Interface from Levtech or the GB-2 and GB-8 boards from Technotrade provide the physical translation between the pump's current loop and a PC's USB or serial port.

With the release of open-source two-wire libraries (e.g., GitHub project "OpenGilbarcoTwoWire"), a Raspberry Pi running a third-party pump controller can now authorize, preset, and totalize an old Gilbarco MPD dispenser. This is a game-changer for research farms, private fleets, and yacht clubs.

Integrating third-party controllers requires specific physical infrastructure to handle the current loop signals:

As fuel stations evolve into multi-functional retail hubs—integrating electric vehicle (EV) charging, alternative fuels, and advanced IoT edge devices—third-party manufacturers are increasingly developing custom forecourt controllers. The protocol follows a master-slave architecture where the

The protocol operates with specific serial parameters depending on the dispenser model: Baud Rate Options 5787 bit/sec

The Gilbarco dispenser two-wire protocol represents a major breakthrough in fuel retailing technology, enabling seamless communication between Gilbarco dispensers and third-party pump controllers. By promoting interoperability, efficiency, and security, the protocol sets a new standard for the industry, driving innovation and competition. As the fuel retailing landscape continues to evolve, the Gilbarco dispenser two-wire protocol is poised to play a key role in shaping the future of the industry.

The Gilbarco dispenser two-wire protocol offers several key features and benefits, including:

While the base two-wire protocol remains consistent, variations exist between older Gilbarco Highline/Legacy pumps and modern Encore 500/700S series. Some newer dispensers utilize extended command maps to handle advanced features like electronic blending and localized error reporting.
