附录A 外文原文 Configure communication 1. Configure communication Introduction This chapter contains information on configuring the communication between WinCC and an automation system. This chapter also describes how you create and scale tags. General procedure Use the editor "Tag management" to configure the communication. You will need at least the following components to configure the communication: = 1 \* GB3 ①One channel with channel units = 2 \* GB3 ②One connection = 3 \* GB3 ③One process tag In practice, you will achieve access to the current process values of the automation system by the configured communication.You do not 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 system as well as the linear scaling of the process tags are only intended as exercises for practice. 2.Check the channels and connections in WinCC Introduction Via the channels and connections you will determine clearly, how the automation system is connected to WinCC. The channels The channels are specialized communication drivers. 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. In WinCC, you can also use channels, via which values are transferred to the automation system from WinCC. You will control the process via these channels. The channel units The channels have different 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 driver and therefore to exactly one communication processor in the computer. The connections In channel units, you will configure connections to the various automation systems. Each connection describes the interface to an individual
