WinCC V6.0技术文档—WinCC 通道“SIMATIC S5 Profibus FDL”(中文)
“SIMATIC S5 Profibus FDL”通道用于WinCC 站和SIMATIC S5 自动化系统之间的通讯。在本事例中,使用的网络类型为过程现场总线(PROFIBUS)和现场数据链接(FDL)。
PROFIBUS 是为中、小型数据量通讯而设计的网络。可连接的节点最多达127 个,可以完成范围广泛的自动化任务。
无论使用的通讯处理器是CP 5613 还是CP 5614,连接设备通过“FDL (CP5412/A2-1)”通道单元与SIMATIC S5 通讯。本通道单元支持最多达24 个连接。为了操作通道,需创建通道单元和连接。

2. Industria1 “system communication
Industrial ial “the system uses the international standard industrial bus. The field controller supports PROFIBUS, FF, MODBUS, can and other countries
International standard fieldbus, PROFIBUS is the most widely used open fieldbus international standard in the world, which is divided into FMS, DP and pa
Level III, DP communication rate can be up to 12MB. PROFIBUS is used to connect distributed i/0 stations, field bus instruments and other intelligent devices.
The communication among process station, operator station and engineer station is realized through the system bus diginets (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin cable, thick cable or optical fiber cable and mixed media) and network topology can be selected for the system bus
Due to the adoption of tcp/ip protocol, the system can also realize ultra long distance communication with the help of public telephone network (dial-up mode) or satellite.
PLC and other subsystems communicate with industrial “system through Modbus protocol interface. The system also supports iec870-5 over control coordination
Discussion.
The flash EPROM inside PS provides more than 220 function modules (control algorithm subroutines), in addition to the base specified in IEC 61131 3 standard
In addition to this content, many powerful and strictly tested function blocks from practical engineering applications are also expanded. Any complex control
All schemes can be realized by the combination of these function blocks.
The function blocks provided by the system mainly fall into the following categories:
o
Analog quantity processing
o
Digital quantity processing
Loop adjustment
Logical sequence control
c
Logical operation
Monitoring function
Acquisition function
c
Arithmetic operation
c
Tcp/ip protocol communication interface
Modbus protocol communication interface
1ec870-5 protocol communication interface (telecontrol)
4.2 field controller PS
Industrial ial “field controller PS is a special process control station, which is embedded with a fieldbus communication interface for users to use
Fieldbus technology provides a very flexible choice. Each PS is allowed to insert 4 fieldbus
