The Master continuously cycles through connected pumps. A typical logic flow is:
Note: If a pump does not respond within a specific timeout window (usually 50ms–200ms), the Master marks it as "Offline" and proceeds to the next pump. The Master continuously cycles through connected pumps
The real "new" breakthrough is hardware. Companies like Bennett Pump’s Third-Party Integration Group, Dover Fueling Solutions (Wayne), and specialized OEMs (such as Tominaga in Japan or EASI in the US) have released next-gen protocol converters. These devices sit between your third-party pump controller and the Gilbarco two-wire loop, performing real-time translation from standard ASCII commands (e.g., "Pump 3, preset 20 liters") into the exact bit-banging current loop required by Gilbarco. Note: If a pump does not respond within
To correctly implement the Gilbarco two-wire protocol, your controller must: Dover Fueling Solutions (Wayne)
The two-wire protocol returns pulses as a frequency. The new converters output these as standard quadrature encoder pulses or Modbus registers. Your third-party pump controller can now read real-time flow data with sub-penny accuracy.
