Introduction

GB/T 25105 is proposed to consist of three parts.

--- Part 1: Application layer service definition. The purpose is to provide a time-sensitive and non-critical communication platform for applications in an automation environment.

Time-critical message communication provides common elements and PROFINET IO fieldbus-specific information, defined in an abstract way the PROFINETIO fieldbus application layer provides externally visible services. It includes. abstract model of application resources (objects);

primitive actions and events of the service; parameters associated with each primitive action and event.

--- Part 2: Application layer protocol specification. The purpose is to define the PROFINET IO fieldbus application layer in an abstract way the externally visible behavior of the application layer protocol data unit transmitted between communication application entities.

The input syntax, the application context state machine of the application service behavior, and the application relationship state machine of the communication behavior.

--- Part 3: PROFINET IO communication profile. The purpose is to define a family of communication profiles for real-time Ethernet (RTE) (CPF3). CPF3 specifies a set of real-time Ethernet communication profiles and a set of IEC 61158 series (type

10) ISO/IEC/IEEE8802-3 and other standard related network components.

RTE performance indicators and the relationship between performance indicators.
