Hi, I'm assuming your are using your ES as single station, since you don't talk about OS server. In this case you need to use WinCC Appl. , not WinCC Appl. Client. Regarding the AS connections. On each AS, you will create a S7 connection to your ES. The result is that in NetPro under your ES station, you have multiple s7 connections leading to each AS system. Before configuring netpro, you will need to setup Station Configurator by selecting the correct WinCC Application and IE general card. Then you will need to do PLC->Configure (by right clicking on the ES station under Simatic Manager) and then PLC->Download to send the configuration to the ES station. Then you will download the stations in netpro so each station will know which connections they have. PS: You can't use several WinCC applications. You only need one, The PG/PC interface is set to PC Internal for each OS station. PC Internal is a virtual bus which can connect to anything like ISO or TCP/IP connections. You will need to set PG/PC interface correctly for each station. When compiling the ES/OS, you can select Named connections so tags are read/written through Named connections which you setup earlier in NetPro (S7 connections). You will have to download each station in NetPro, not only the ES because the AS systems need to know also which connections they have.

Hi, The only way you want to insert an ES station is that you want to use it for OS simulation of the process. You won't need to insert several ES stations... In a normal standard PCS7 setup you have: 1 ES 1 OS or 2 OS servers redundant x Clients x Referred client PCS7 prefers to use a multiproject. In the multiproject several subprojects are inserted: ES project OS project with OS server(s) Client project with all clients/referred client AS project (Each AS has it's own project) If you use subprojects, then you need to Merge all connections to a project wide connection. So in your AS project is a plant bus called: "PlantBus AS1". In AS2 it's called "PlantBus AS2" etc. In your OS project is a plant bus called: "PlantBus OSServer". When ready, you can merge all these subnets into one project wide plant bus connection. You can do that via the properties of your multiproject. When ready, you can open NetPro in project wide view and all stations AS+OS are visible. Please check the documentation like PCS7 Engineering Station or the Getting Started manual. It explains how to setup your project. So, delete all the ES stations except one.

S7_connection is for connection only. For ES, we need it if you are going to setup OS simulation. If you really want to do so, you need to add wincc application, but not wincc application client. Then delete the OS that attached to the wincc application. In order for you to set to pc internal local, the most important one is to configure your IE general or CP into station configurator. And, WinCC application client doesnt need to configured IE general to the station manager. it communicates with others via terminal bus. For me to set up multiple AS with one ES, i will combine them into one multiproject. Then set the pg interface to the network adapter that can see the plc node. Download all of them one by one. Once the linkage between them done, i will set the pg interface to PC internal local and configure the ES station configuration. And make sure the netpro connection is correct-> this means the IE general/CP card should connect to the those PLC PN-IO ports in the network. With this, they should be able to communicate already. For S7_connection, it is important for WinCC to get the data from CPU. so you would need to configure the connection between them, OS - AS. Hope this helps. Thanks. |
