GB/Z 29619.3-2013

This standard defines the data link layer services for the INTERBUS fieldbus protocol, specifying how data frames are structured, transmitted, and managed between devices in industrial control systems. It is applied in manufacturing automation environments, such as factory assembly lines and process control systems, where INTERBUS networks connect sensors, actuators, and programmable logic controllers (PLCs) for real-time data exchange. The standard ensures consistent communication behavior across devices from different vendors, enabling reliable and deterministic control in industrial settings.
