Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New Updated Guide

The answer is . UL and ATEX certification for hazardous locations (Class I, Division I) prohibit unlicensed radio transmitters inside dispenser cabinets. The two-wire loop is intrinsically safe (with proper barriers). The new trend is "Two-Wire-to-5G" gateways: a third-party pump controller located in a back office (or the cloud) sends HTTPS requests to a small gateway box, which then speaks two-wire to the dispensers.

For decades, the fuel retail industry has operated in a state of semi-walled gardens. Major dispenser manufacturers, particularly Gilbarco Veeder-Root, developed proprietary communication protocols that made it notoriously difficult for third-party point-of-sale (POS) systems, fleet fueling managers, and automated tank gauge (ATG) integrators to communicate directly with the dispenser’s hydraulic components.
