Hello foperious; It would be interesting to see what kind of project you are developing. The number of CPU ressources per HMI is very limited. How can you optimize an HMI connection and what has to be considered regarding the connection resources? (HMI operator panels with S7-1200 or S7-1500 controllers) https://support.industry.siemens.com/cs/ww/en/view/109479986 But the following FAQ shows how you can "multiplex" your connections with the panel: How do you change the connection from the operator panel to the controller? https://support.industry.siemens.com/cs/ww/en/view/67653385 Two things have to be taken into consideration (among other things...) depending on what you want to do: - what kind of performance are you expecting from this system; changing connection parameters takes a few seconds, and the overall performance will degrade as the number of connected CPUs goes up. - the total number of tags in the panel is limited to 2048. If you plan to share them with up to 50 CPUs, each controller will have only 40 tags to read/write to the HMI... Hope this helps, |

Is there any other way to control and supervise those plc's through the internet with a web interface for example?

Yes It will be possible if you access this PLC to your work location via VPN. There is web server feature available for S7-1200/S7 1500 controller.You can can configure HTML pages for the same. Below links may be help you. 1.Creating and using user-defined web pages on S7-1200 / S7-1500 2. Siemens S7-1200 Web Server Tutorial - From Getting Started to HTML5 User Defined Pages also there some VPN devices which have inbuilt web server you can create your own MIMIC screen and control PLC operation Amol Gaikwad |

the web server concerns one s7-1200 at a time right? Is there any way to make a web server for more than one plc? |

Hi foperious, hope you tested it and it is working okay. Otherwise this link will be helpful to you.Use Siemens HMI/SCADA for visualization at work location. 1.WinCC Runtime Professional as you can connect with 64 PLC 2.WinCC Runtime Advanced Can support max 8 PLC connection. 3.Comfort HMI max 8 PLC Connection. If you want use web based solution then you can use third party solution. Br, AmolG. AttachmentComm.pdf (63 Downloads) |
