Hello, you can't connect 50 plc to wincc directly. Make a PPI network to connect your PLC's together collect the data on 1 or more PLC's and then send it to Wincc. How is data exchanged between two SIMATIC S7-200 devices in PPI mode? What are the options for accessing an S7-200 with WinCC? Regards, Marcjan |
Problem solved? |

Hello Eshwar; Marcjan's suggestions are valid, please take a look at the following FAQs on PPI interfacing for S7-200 (to collect data in a max. 8 number of data conentrators for exchanges with WinCC), and PC Access connection with WinCC: How is data exchanged between two SIMATIC S7-200 devices in PPI mode? |

Hello Eswar; WinCC v. 7.0 comes in 2 versions (development ("complete")and runtime) and is configured by the number of external tags required for your application. See the following Product description from the Siemens Industry Mall; you can also check the Ordering Data tab to look for the part number you would need. https://eb.automation.siemens.com/goos/catalog/Pages/ProductData.aspx?language=en&nodeid=10042373&tree=CatalogTree®ionUrl=/#topAnch&activetab=product& SIMATIC WinCC is available as a complete package and as a runtime package with 128, 512, 2048,8192, 65536, 102400, 153600, 262144 PowerTags 1). PowerTags are data points that are connected to controllers or other data sources over a WinCC channel. So I would calculate the number of tags (data registers) you want to rread from each S7-200 PLC, calculate the total number, keep some room for extras, and purchase one WinCC package that would cover your needs. Hope this helps, Daniel Chartier |
