Gilbarco Dispenser Twowire Protocol For Third Party Pump Controllers New ((new)) File

Connecting a standard PC or a modern PLC to a Gilbarco dispenser often requires an interface converter to bridge the gap between RS-232/USB/RS-485 and the 2-wire current loop.

Uses an 11-bit data format for maximum throughput. Connecting a standard PC or a modern PLC

For newer installations, Gilbarco has introduced high-speed communication technologies like the Invenco Link Connecting a standard PC or a modern PLC

The protocol follows a architecture. The pump controller (Master) initiates all communication by polling the dispensers (Slaves). Every unit on the loop receives the data, but only the specific unit addressed responds, while others ignore the message. Interface Requirements for Third-Party Systems Connecting a standard PC or a modern PLC

To successfully integrate a third-party controller, the following physical and logical parameters are standard:
