how read the IP address for PLC from Hardware?

[SevenMag]

wie Sie die IP-Adresse der PLC von Hardware lesen?

[SevenMag]

I'm found number Rack and Slot for CP and CPU (3xx and 4xx) in file HOBJECT1.DBF column SUBSTATN is number rack, column MODULN is slot. checked in more S7 projects with H-system. You can add to LibNoDaveConnectionLibrary ?

[jogibear9988]

Have you also find out where the IP is stored?

[SevenMag]

I am looking for. But it's not easy.

Ich bin für. Aber es ist nicht einfach.

[jogibear9988]

Ich glaube die sind eher im Ordner CONN... also nicht bei der Hardware! Aber sicher bin Ich da nicht...

[jogibear9988]

I've also tried again. I used Winmerge, and compared two projects after changeing a IP, but I had no success

[SevenMag]

Ich glaube die sind eher im Ordner CONN... also nicht bei der Hardware!

No. IP address is in file \S7Netze\S7NONFGX.tab as hex to string. exsample: ip = 192.168.2.200; string = "C0A802C8"; file S7NONFGX.tab has this string, but many times. Where is the offset for each CPFolder I have not found.

[jogibear9988]

The Byte before the IP Adress String is the Length of the String.

[SevenMag]

The Byte before the IP Adress String is the Length of the String.

Pascal? This file also has mask and MAC-address. When save hardware without changing the file changes.

[jogibear9988]

Pascal? what do you mean?

[SevenMag]

Pascal has string as: first byte is length, the rest up to 255 bytes is text. it simply washed. I have a few ideas on this file, I will try

[SevenMag]

I'm disassembled file S7NONFGX.DLL, but that does not found.

[jogibear9988]

What do you mean?

[SevenMag]

File S7NONFGX.DLL is the only file that has a string of "S7Netze", then it reads the file "\S7Netze\S7NONFGX.tab", but in this file I could not find how to read this structure with IP, mask and MAC.

[jogibear9988]

here is also little bit info:

http://www.sps-forum.de/hochsprachen-opc/73225-s7-projektdateien-ip-adressen-auslesen-2.html#post509151

[SevenMag]

so einfach? bravo!

[SevenMag]

I found for the CP: IP address, MAC, mask and router, but only for simple CP. For 6GK7443-1EX20-0XE0 ( which has 2 Ethernet ) compliance can not find.

[SevenMag]

I'm a little confused. made changes in two pull Requests.

[jogibear9988]

I will modifie your changes a little bit, because for Example a CPU or PG can have more than one Network Interface...

[SevenMag]

Good. CP 6GK7443-1EX20-0XE0 has two network interface, but not fill this code.

[jogibear9988]

I need the code of "IndexOfByteArray"

[SevenMag]

ups. sorry. something like this:

    public int IndexOfByteArray(byte[] array, byte[] pattern, int offset, int maxLen)
    {
        int success = 0;
        int length = array.Length;
        for (int i = offset; i < length; i++)
        {
            if (array[i] == pattern[success])
                success++;
            else if ( success > 0 )
            {
                ii--;
                success = 0;
            }
            if (pattern.Length == success)
                return i - pattern.Length + 1;
             if ( --maxLen == 0 ) return -1;
        }
        return -1;
    }

[SevenMag]

more:

      if (cp.IP != ip) 

always is TRUE. need change to

     if (cp.IP.ToString() != ip.ToString() )

[SevenMag]

1. why CP is added only when TobjTyp == 1314972? I have project with row["TOBJTYP"] is 1314972 and 11314865, so the draft CPFolder was empty.
2. file \s7wb53ax\HRELATI1.DBF: row["TOBJID"] need to remember when row["RELID"] is equal to 64, otherwise TobjId is not valid.

[jogibear9988]

in my test project every cp is added twice (lean 340) so i looked in the hrelatio file and se, i have two entrys for every cp. but i will overwoek it, i also see in the hobject dbf in this folder also the ports seem to be in that file... i will look to repair it, maybe today, or tomorrow....

[SevenMag]

Today I downloaded the new version, in my project, he showed the CPFolder.Count = 0, I removed the condition "if (x.TobjTyp == 1314972)", the CP appeared, but without Network. Corrected as I sent yesterday, appeared Network. Add "pull Requests" with my changes?

[SevenMag]

I can send the project on which I am trying to

[jogibear9988]

why is your network info missing? i changed nothing on your reading code!

[jogibear9988]

i mean nothing functional!

[SevenMag]

in "//Get The CP Folders" i'm add code:

            int sobjid;
            foreach (DataRow row in dbfTbl.Rows)
            {
                if (!(bool)row["DELETED_FLAG"] || _showDeleted)
                {
                    if ((int)row["RELID"] == 64)
                    {
                        sobjid = (int)row["SOBJID"];
                        var cp = CPFolders.FirstOrDefault(x => x.ID == sobjid);
                        if (cp != null)
                            cp.TobjId = (int)row["TOBJID"];
                    }
                }
            }

you do not have this

[SevenMag]

Yes!!!!!! I found a match for the CP with 2 network interfaces.

[SevenMag]

[jogibear9988]

With your Code, and remove my x.TobjId = Convert.ToInt32(row["TOBJID"]); I get not CP Folder!

I look for it at the weekend...

[jogibear9988]

Maybe you can send me also your Project...

[SevenMag]

I sent a test project and 2 file with the new changes for reading in the Multi-Interface CP Please send me your project, I'll see why we read differently IP

[SevenMag]

I sent the file Step7ProjectV5.cs it has 3 lines:

                    byte[] bbb = new byte[1960];
                    Array.Copy(completeBuffer, position, bbb, 0, 1960);
                    File.WriteAllBytes(@"d:\Temp\Temp\" + number + ".txt", bbb);

they help to find small changes, but in the release are not needed.

[SevenMag]

hello received a project Test2. looked. Very strange situation, in my project was simple. If you look in the reverse order, then: S7NONFGX.tab file has 5 structures beginning with 0x03, 0x52, 0x14, 0x00, ie 5 addresses. these structures number: 3.4, 6, 7, 8. file \s7wb53ax\HRELATI1.DBF with row["RELID"] == 64 only 4 addresses: 4, 6, 7, 8; file \s7hssiox\HRELATI1.DBF(for multi-Interface) with row ["RELID"] == 64 has address 3. but how to compare the values ​​of CP and it is hard to find. and more: project Test2 has 8 CP, may be 3 CP is profibus.

I hope these thoughts as they will help. Ich hoffe, dass diese Gedanken, wie sie helfen

[SevenMag]

I now checked my code for 30 different projects, always determine the correct IP address. For project Test2 I had an idea how to compare, but to test this idea a little project.

[impoetk]

Which code you use for reading the IP address?? I get the cpufolder but the property NetworkInterfaces is always null. Should I run some code before to parse the addresses?

[jogibear9988]

Yes SvenMag, can you create a Git Pull Request, with the changes yu have to the current Master Branch? I've now reverted my changes to reading from the hrelatio.dbf. I will add your Code that works for your Projects, still I've no time at the moment to look into this.

[SevenMag]

I'm change my project (https://github.com/SevenMag/DotNetSiemensPLCToolBoxLibrary) for read IP. now read IP for CPU with ethernet, for CP with 2 Ethernet and another CP. Please testing.

[jogibear9988]

I send you a Project wich does not work. There are read now 4 CP's (it only has two), in my Tree in the Toolbox, only the two are shon, but the other two get the IPs. I think we have two combine this two CP entrys in any way! And the IP of the CPU is also not read!

[SevenMag]

I'm add to CPFolder one more CPFolder as SubModul, see it. CPU in project Test2 (sent me an e-mail) I read IP normal. maybe it's the other project?

[SevenMag]

may be a little to alter the reading of the DB-files. In each folder, you first need to read HOBJECT1.DBF and then HRELATI1.DBF. UNITID in HRELATI1 is ID in the HOBJECT1.DBF

[SevenMag]

When HW Config shows two CP, but raed 4 this is may be because the 2 Ethernet CP and 2 CP Profibus. We must unite and do 2 NetworkInterfaces for each CP

[jogibear9988]

Can I send you a Example Project? (I thought I did, but I don't find your EMail adress, i replied to github...)

[SevenMag]

Yes. send to berlyakov.ev@npoa.mmk.ru

[SevenMag]

I have not received anything.

[SevenMag]

We have found for the networkInterface: IP, MAC, Router, Name; I have found a property useIP, useISO, useROUTER; There are many options, I found 32. But I think others do not want, or something you want?

[jogibear9988]

I send it to you now...

[jogibear9988]

If there are more options you read out, feel free to create Properties and fill them...
