I have never worked with more plc and central PC so my question is, will it work? How i imagined it: Every process is controlled by it's own PLC and has it's own touchpanel for local control. Now i need to set up a main computer which will be in main control room and would be possible to display variables from all PLCs in the network(central HMI). Maybe also, controlling PLCs over that PC would be needed. Would it be possible to accomplish this with a regular PC autostarting the Wincc Runtime on boot? How would they be connected(PC and PLCs over Ethernet over switch)? Please shed some light if someone knows more about this topic? PLC type would be S7-300 series Back to top rott Senior Joined: 23 Aug 2011 Posts: 2266 Posted: 16/12/2013 22:27    Post subject: Re: Controlling several PLCs dbozic wrote: I have a question regarding the setup of network.

PLC type would be S7-300 series Hello dbozic, You have here some documentation about how it works Communications and HMIs... My advice is to download and install for example Step7 v5.5 and WinCC 7.2 and WinCC Flex 2008 SP3 and Simatic Net 8.2..install all these and you'll find documentation and eventually you can try to make projects on your own....

Every PLC and HMI has to be programmed with some DB(Data Bloks) which functions as Data Buffers between all applications . Using some specialized functions for Send/Receive Data on PROFIBUS, PROFINET, INTUSTRIAL ETHERNET, all PLCs and HMIs takes the data which are useful for itself....This is the general concept... How to do and how to program...this must be learned....
