GB/T 25110.2-2010

This standard specifies the requirements for a hybrid communication bus that combines both real-time and non-real-time data transmission within distributed industrial automation systems. It is applied in manufacturing environments, such as factory floors and process control systems, where devices like sensors, actuators, and controllers need to communicate over a single bus while meeting diverse timing and reliability needs. The standard ensures interoperability and consistent performance in mixed-criticality industrial networks.
