    Excellent, it works like a charme. In my case, I had a S7 1200 without the ability to use the dbRead command, so I just tried the ReadArea method and it worked as intended.

    @Mesta Automation I have a question. Is there a way to run a code that gets the data’s automatically . For example I run the C# code and now the code once read all variables. Now the code is like in a standby mode and just read variables again when the variables got changed. I hope u understand what I mean.

    Hi
    Thank you very much for your video.
    I can connect to s7-1200 plc because of your codes. But i've got an error message while i was trying to read DB.
    Error: ISO : Invalid Buffer passed to Send/Receive
    What can i solve this problem?

    Hi Mesta, really interesting video. I'm interested in getting information into Unity3D from TIA Unity uses C# as one of its scripting languages do you think that sharp7 would be easy to use?

    • @Mesta-automation
      @Mesta-automation  7 років тому

      I never used Unity, but since it's capable of using .Net sockets, you should be able to use Sharp7. Someone already asked me the same question and in the end he got the communication up and running. Still, I don't know how difficult it was for him.

    Hello! Can you tell me what library is better, S7.Net, Sharp7, libnodave, whatever? Or maybe better use ModBus or raw TCP packets (TSEND_C/TRECV_C)?

    I've got a WORD variable at DB6.DBW272 and I can't get this value. Does it mean that address 272 is to big? If yes, then what is the biggest address in DB block? Please answer me, maybe I'm doing something wrong

    I found 1 problem. When I have the value -1 in db2dbw2 and i want to get it to the VS, then I see that instead -1 the value is 65535. So this is still a posituve value. How to change it into negative?

    • @Mesta-automation
      @Mesta-automation  7 років тому +1

      Yes, you can create as many S7Client you like, then use ConnectTo to assign ip to every different client. Every S7Client instance should have it's own ip.

      Sharp7 is C# only, Snap7 is C++ with a C# wrapper.

    is it tested on real operation with a real PLC and working? What version .net you need to make it work? I would like to put it together with Unity Game engine and make the magic happen. But I fear I wont be able to maintain this in asynchronous operation while a main thread do the game engine magic.

      People already did things with Unity and Sharp7. Run a search for "Unity" in the commens of: www.mesta-automation.com/how-to-write-a-siemens-s7-plc-driver-with-c-and-sharp7/

      In your opinion wich driver you feel more confortable with, Sharp7 or S7.Netplus? I made unity work with S7.netplus cause its a plane dll you import to unity, but Sharp7 feels more robust and the documentation is great.

    "byte[] db1Buffer = new byte[44];
    result = client.DBRead(1, 0, db1Buffer.Length, db1Buffer);". I see this code, but i dont know how to determine DB number, start value and size. Any one can help me, please? thank you!

    • @Mesta-automation
      @Mesta-automation  7 років тому

      That instruction is reading DB1, from index 0, 44 bytes, and it's putting the result on db1Buffer.

      Hi!
      as I understand you correct, you may need to change the default IP of the PLC, it's 0.0.0.0 as I know
      Check this article to make it clear: support.industry.siemens.com/cs/document/41737436/how-can-you-change-the-ip-address-of-an-s7-1200-without-using-step-7-basic-?dti=0&lc=en-WW
