对于某些重要的对象和数据进行操作,根据需要可以在操作过程中触发操作员输入消息,本文主要介绍操作员输入消息的组态方法,GCreateMyOperationMsg函数的简单应用。
对于某些重要的对象和数据进行操作,根据需要可以在操作过程中触发操作员输入消息,操作员输入消息根据操作的对象和操作类型的不同,分为以下三类:
1、“图形编辑器”中相应对象的属性中有“操作员输入消息”选项,例如:在I/O域中输入数值,文本列表中选择文本等。
2、对于操作可选图形WinCC对象,其属性中没有“操作员输入消息”选项,例如:对于按钮的操作等。
3、在控件中对于消息操作,例如确认锁定/释放消息等。
I/0 stations and field bus instruments.
Communication between the process station, operator station and engineering station takes place via the system bus DigiNetS (Industrial Ethernet). user
Different transmission media (RJ45 twisted pair, thin, thick or fiber optic cables and mixed media) and network topology can be selected for the system bus.
Simple layout, due to the use of TCP/IP protocol, the system can also use the public telephone network (dial-up mode) or satellite to achieve ultra-long-distance communication.
Subsystems such as PLC communicate with the Industrial” system through the ModBus protocol interface. The system also supports IEC870-5 over-control protocol.
discussion.
The Flash EPROM inside the PS provides more than 220 functional modules (control algorithm subroutines), in addition to the basic ones specified in the IEC 61131 3 standard
In addition to this content, many powerful and rigorously tested function blocks from actual engineering applications have been expanded. any complex control
The scheme can be realized by the combination of these function blocks.
The function blocks provided by the system mainly include the following categories:
o
Analog processing
o
digital processing
loop regulation
Logical sequence control
c
logic operation
Monitoring function
Collection function.
c
arithmetic operations
c
TCP/IP protocol communication interface
Modbus protocol communication interface
1EC870-5 protocol communication interface (Telecontrol)
4.2 Field Controller PS
Industrial” field controller PS is a special process control station, which is embedded with field bus communication interface for users to use
Fieldbus technology offers very flexible options. Each PS allows to insert 4 fieldbus interface cards (the card type can be different),
Each card is connected to 1 field bus to collect process data and diagnostic information from the bus, the interface card is easy to replace and plug and play
(Plug & Play), and can be plugged and unplugged.
The field controller PS has the following characteristics:
o
Flexible: supports all international standard open fieldbuses and can be mixed
Simultaneous connection of 4 high-speed fieldbuses (max. 12 MBd)
Simple engineering: configuration, commissioning and diagnostics using only the same tool CBF (Control Build F) software
mouth
Access to all information from the field including equipment management information
Global database of fieldbus devices, control levels and HMI (Human Machine Interface) usage systems
Module identification with production
