Introduction
INTERBUS is a digital serial communication system used in control systems (such as programmable logic controllers) and industrial sensors and actuators
Communication between field devices. These devices include simple limit switches and valves, as well as measurement sensors, measurement transmitters and actuators, and also
Can include sophisticated high-tech control systems such as controllers that control drive, torque, and process.
This section describes the physical layer specifications and services, which is closely related to GB /Z 29619 other parts. GB /Z 29619 by the Department
Separately define the "three-layer" reference model of the fieldbus that is the basic reference model for system interconnects. For ease of management, both reference models will be interactive
Even the standard range is subdivided into a series of normative layers. The relationship between the different layers shown in Figure 1.
NOTE The system management used in this section is a local mechanism for managing layers of protocols.
Figure 1 physical layer and other layers
The main purpose of this section is to provide a set of communication rules that are expressed by the procedures that peer physical layer entities implement when communicating.
The physical layer receives the data units from the data link layer, encodes them, adds communication frame information if necessary, combines the synthesized physical information
Number to a node on the transmission medium. The other node then receives the signal, decodes it, and passes it to the receiving device if necessary
Before the data link layer, but also delete the communication frame information.
This section contains the physical layer specification, corresponding to the DL-Layer protocol GB /Z 29619.4.
The physical layer of the general model shown in Figure 2.
Figure 2 physical layer generic model
The physical layer allows the transmission of received data units to another device through direct media access; it also allows access through other media
Ask about its transport protocol to transfer data units to another device.
The following types are specified.
--- Twisted pair media, the maximum rate of up to 16Mbit/s;
--- Fiber media, the maximum rate of up to 16Mbit/s.
The general characteristics of these transmission media are.
--- Full duplex transmission;
--- Not zero (NRZ) encoding.
The wire media type offers the following options.
--- Non-bus power supply, non-intrinsically safe;
--- Through the bus and other additional wire power supply, non-intrinsically safe.

Part 2. Physical layer specifications and service definitions
1 Scope
GB /Z 29619 provisions of this part of the requirements of the physical layer components. Also provided for the media and network configuration requirements, to ensure.
a) data integrity before data link layer error checking;
b) Interoperability between physical layer devices.
The fieldbus physical layer complies with the first layer of the OSI 7-layer model of GB/T 9387.1.
