2、tion on configuring the communication between WinCC and an automation system. This chapter also describes how you create and scale tags.</p><p>　　General procedure</p><p>　　Use the editor "

3、Tag management" to configure the communication. You will need at least the</p><p>　　following components to configure the communication:</p><p>　?、貽ne channel with channel units</p>

4、<p>　?、贠ne connection</p><p>　?、跲ne process tag</p><p>　　In practice, you will achieve access to the current process values of the automation system by the configured communication.You do n

5、ot need an automation system for the "Quick_Start" project. In this project, the values are transported via an internal tag within WinCC.The configuration of the communication between WinCC and the automation s

6、ystem as well as the linear scaling of the process tags are only intended as exercises for practice.</p><p>　　2.Check the channels and connections in WinCC</p><p>　　Introduction</p><p

7、>　　Via the channels and connections you will determine clearly, how the automation system is connected to WinCC.</p><p>　　The channels</p><p>　　The channels are specialized communication driv

8、ers. The channels allow the supply of process values from the automation system to the process tags. WinCC provides a variety of channels to connect different automation systems.</p><p>　　In WinCC, you can a

9、lso use channels, via which values are transferred to the automation system from WinCC. You will control the process via these channels.</p><p>　　The channel units</p><p>　　The channels have dif

10、ferent channel units for the different communication networks. This channel unit is then used to access to a certain type of automation system. A channel unit serves as an interface with exactly one underlying hardware d

11、river and therefore to exactly one communication processor in the computer.</p><p>　　The connections</p><p>　　In channel units, you will configure connections to the various automation systems.

12、Each connection describes the interface to an individual, defined automation system. The data exchange will take place via the connections in Runtime.</p><p>　　3. Tags in WinCC</p><p>　　Introduc

13、tion</p><p>　　The tags in WinCC represent either real values or internal values. The internal values are calculated or simulated within WinCC. WinCC manages all tags in the "Tag management" editor.

14、</p><p>　　Process Tags</p><p>　　The connecting link for the exchange of data between WinCC and the automation systems are the external tags. Each external tag in WinCC corresponds to a certain p

15、rocess value in the memory of one of the connected automation systems. External tags are therefore referred to as process tags.</p><p>　　In Runtime, the process values of the process tags are determined and

16、entered by WinCC.</p><p>　　In WinCC, you can also determine the values for the process tags. These values are transferred to the automation system via the stipulated channel. The automation system controls t

17、he process accordingly.</p><p>　　Internal Tags</p><p>　　WinCC also has internal variables. These tags do not have a process link and only carry values within WinCC.</p><p>　　Tag gro

18、ups</p><p>　　The tag groups are components of the "Tag management" editor. The tag groups are used to organize tags clearly.</p><p>　　4.Adding a Channel</p><p>　　Introduct
