There's no official documentation about this. I think if you inspect the communication using wireshark, you can see many things of what's going on. For S7comm-plus you'll need a plugin dll which I provide here at sourceforge. But with current controllers the communication is encrypted, and you wont't see much of the details. In this project you'll find no information about the S7 protocols, as it tunnels the Iso-On-TCP payload into the internal S7Online-Interface, whithout processing the details....

Hi, it seems you haven:t downloaded the HW-Configuration to Plcsim, as you can see in the statusbar of the Plcsim window, it shows the default IP: 192.168.0.1. Use the browse dialog in Nettoplcsim to find the available Plcsim address and also network address. In 99% of the use cases, the address you can use must be available via the browse dialog. Your configuration with different IP addresses at "Network" and "Plcsim" may work then after you downloaded the HW-Config. If the network address on which...

Hello guys Iam having an issue simulating ix developer with step 7 . Iam using a virtual machine , so both ix developer and step 7 work in the same VM. I use NetToPLCSim to make the connection , but iam having trouble . I disabled firewall and antivirus , i can also monitor values in step 7 I sent the pictures of my configuration below . I tried both 10.0.230.40 and 10.0.230.100 in the controller tab in ix developer , but i still get communication error. I appreciate your help ! Best regards

Wichtig ist, dass es jetzt funktioniert. Und das es bei dir auch mit 127.0.0.1 funktioniert ist auch eine gute Information.

Also das Movicon Projekt läuft aktuell ohne Probleme in einer Anlage. Ich soll nur ein paar Änderungen an der Visualisierung vornehmen und die wollte ich halt in der Simulation testen. Die Anlage ist ein paar Stunden entfernt und wir haben keine Yaskawa Panels um es im Büro zu testen. Ich habe aber durch Zufall den Fehler gefunden. Movicon scheint 2 verschiedene Simulationen zu haben. Es gibt das "aktuelle Projekt starten" und das "aktuelle Prozessbild starten". Da ich tatsächlich eins der Unterprojekte...
-
Der Test liest also erfolgreich das MB0, darum würde ich sagen, liegt es vermutlich nicht an Nettoplcsim. Hast du das Movicon denn schon einmal erfolgreich an einer echten SPS getestet? Vielleicht sind deine Variablen nicht korrekt angelegt, falsche Adresssyntax oder dergleichen. Bei Movicon kann ich dir leider nicht weiterhelfen, ich habe nur an einer Anlage mit Movicon etwas gemacht, und da lief die Anbindung an die S7 über einen OPC-Server.
-
Also im Monitoring sehe ich Verbindungsversuche wenn ich die Kommunikationstestfunktion nutze. Wenn ich aber die Simulation starte passiert nix. Habe auch ein Bild vom Monitoring Fenster angehangen. Im Bild Movicon Station sind Rack und Slot vom Backup zu sehen. Dadrüber sind dann die normalen Rack und Slot mit 0 und 2. Genauso wie es für eine 300er sein soll. Mit der Netzwerkschnittstelle habe ich es auch schon probiert aber leider auch kein Erfolg.
-
Ich kenne die Movicon Anbindung nicht, aber warum steht bei deinem ersten Bild Rack 0 und Slot 2? Bei einer 300er ist das im Normalfall immer Rack 0 Slot 2 (Sonderfall wäre ein CP und Verbindungsmultiplexen, aber das macht so gut wie niemand). Wobei das bei Nettoplcsim nicht zum Tragen kommen sollte, aber spätestens an einer echten CPU. Du kannst mal mit Rechtsklick mit der Maus auf die Zeile PLC#001 das Monitor Fenster öffnen. Da sollte ersichtlich sein, ob überhaupt ein Verbindungsversuch erfolgt....
-
So ich melde mich mal wieder. Seit meinem letzten Kommentar funktioniert es wieder nicht. Movicon besitzt einen Kommunikationstest. Der funktioniert. Habe von der Erfolgsmeldung ein Bild angehangen. Aber wenn ich die Simulation von Movicon starte baut diese trotzdem keine Verbindung zur PLCSim auf. Versionen haben sich nicht geändert. Es ist jetzt sogar ein anderes Movicon und S7 Projekt. Ich hänge Bilder von den Kofigurationen an.

Thanks, now I change the drive before and now it's working. Perhaps it's the same issue as it is not possible to change drive with a "cd D:\xxx" command, you have to do a "d:" and a "cd xxx". Greetings
-
Hi, interesting, you need to be in the correct drive to get this working. If you do a d: on the commandline to change the drive to D: then it's working. I'll have to check why it's not using the drive letter. But whis this fix you hopefully get this running.

Hi, I've tried the commandline-parameters, but it does not work. What is wrong on "D:\Nettoplcsim-S7o-v-1-2-5-0\bin\NetToPLCsim.exe -f=D:\Nettoplcsim-S7o-v-1-2-5-0\bin\GFW.ini -s=YES -autostart"? Ini-File is in the program-folder, also tried with no path, "-f=GFW.ini" BR

Natürlich kannst du Movicon auf dem einen und Plcsim/Nettoplcsim auf einem anderen PC laufen lassen. Solange beide über Netzwerk miteinander verbunden sind funktioniert das. Ich würde sagen, das ist auch der meistgenutzte Einsatzfall.
-
Jetzt ist es interessant. Ich habe heute morgen meinen Grafiktreiber deinstalliert und eine ältere Version installiert und jetzt funktioniert auch die Kommunikation zwischen Movicon und Nettoplcsim. Ich kapiers nicht.
-
Ja es läuft bei mir alles auf dem selben Rechner, da man sonst keine Verbindung zwischen Plcsim und Movicon herstellen kann für Simulation. Also letztes Jahr Dezember hatte es auch schon mal funktioniert. Ich habe für Testzwecke auch einem Kollegen mal meine Step7 und Movicon Projekte geschickt. Bei ihm hat es sofort geklappt. Wir haben die selben IP-Adressen eingestellt und nutzen auch die selbe Version von Nettoplcsim. Der Kollege war es auch, der mir gesagt hat ich soll bei Nettoplcsim die Network...

Dieser virtuelle PLCSIM Adapter ist für Plcsim Advanced. Plcsim Advanced ist aber wenn nur für das TIA Plcsim der 1200/1500er Steuerungen, und dafür benötigst du dann eine separate Lizenz brauchst aber kein Nettoplcsim mehr. Für das Step7 Plcsim ist dieser Adapter aber nicht zu gebrauchen. Und wenn du kein Plcsim Advanced hast, dann würde ich diesen komplett deaktivieren, denn er stört auch an anderer Stelle. Aber 127.0.0.1 in Movicon wird nicht funktionieren, wenn Nettoplcsim einen Netzwerkadapter...

Hi, schreib bitte mal auf: - Welche IP Adresse besitzt die SPS, und welche IP-Adresse hast du in deiner Movicon Software als SPS IP-Adresse eingestellt? - Welche IP-Adresse besitzt der PC wo Plcsim/Nettoplcsim läuft, und welche IP-Adresse hast du in Nettoplcsim als "Network address" eingestellt? Nettoplcsim nutzt eine vorhandene Netzwerkschnittstelle am PC, d.h. wenn der PC mit Plcsim/Nettoplcsim unter der gleichen IP wie später die echte SPS erreichbar sein soll, musst du dem PC die gleiche IP-Adresse...

Moin Thomas, Ich bin gerade dabei ein Projekt zu simulieren. ich nutze S7-PLCSIM V5.4 + SP8, Simatic Manager V5.7 + SP2, NetToPLCsim V1.2.5.0 und Movicon 11.6. Ich kann den NetToPLCsim Server ganz normal erstellen. Dann kann ich mit der Test Cable Funktion von Movicon eine Verbindung herstellen aber wenn ich die Simulation von Movicon starte kriege ich keine Verbindung. Woran könnte dies liegen?

Thank you, you were right, I disabled network cards from PLCSIM advance, such as "virtual ethernet" and "hmi ethernet adapter". Rebooted the computer and first of all enabled nettoplcsim, so that it occupied port 102 and it worked. I use Tia Portal V16 and plcsim advance v3.0 upd1.
-
Which version of TIA Portal / Plcsim advanced? Does the classic Plcsim start, or at what point does an error occur? I had V18 with Plcsim Advanced installed but not used, without problems with Nettoplcsim. I just installed V19 which also updated Plcsim Advanced, and I encountered the problem that my VMWare machines weren't able to communicate to the outside network. I had to disable the Plcsim Advanced virtual network adapter to get this fixed. But haven't tested if there are also problems with Nettoplcsim....

After installing plcsim Advanced, nettoplcsim stopped working. There is a project on s7-300 that needs to be supported remotely, HMI Weintek. Has anyone encountered this?

Thanks Thomas! It answers my question to a great extent. Currently I use a PLC to create a opc ua server and using opc ua library on python to read the tags and write to it. Is there a way to do the same using Nettosim and PLCSIM on tia portal V17. If so then it would be a great benefit. Also I wanted to understand the extent of support Nettosim offers to using ignition Scada platform. Thank you in advance.

Hi, Nettoplcsim with standard Plcsim does not support the simulation of the OPC-UA server on the CPU. You need Plcsim-Advanced for this, then you don't need Nettoplcsim at all.

I had set the following configuration: Set the PG/PC interface to PLCSIM.TCPIP.1 Set up PLC SIM, with OPC UA Server running and loaded the program Set the ip address of network as the local ip adapter ( just connected two pc with ethernet cable to get this IP) Set the simulation ip to the ip shown on the PLCSIM Started the server After all this I was unable to connect to the server by using FreeOPCUA client or even Ignition Scada

Hello, I have the same problem. I could not communicate with Delta dopsoft and Tia portal plcsim. I made the above settings. I am using Tia portal V14sp1, plc sim, dopsopft V4. Please help.
-
The Nettoplcsim interface only allows S7 communcation as server. And no two way communication is supported. The only way it should work, to let the real Plc act like the WinCC. Means, add an unspecified connection from the real plc to the plcsim cpu, let it be the active partner, and call the Put/Get blocks in the real plc.

As an author you sometimes don't know what is relevant for an user which is new to the program. I think it's only relevant to know, that Nettoplcsim for the Network address doesn't do any magic in the background. It just uses the existing interface, which you have to setup for yourself with the standard Windows tools. If you want the PC where Nettoplcsim is running on, should be reachable at the same address the real Plc will have. you have to set the network interface IP address to the same as the...

Okey, solved it. The manual is very misleading. Do not load the Systemdata. Set IP of your VM/PC to the address that is supposed to be used by PLC. I wanted PLC to use address 10.166.98.20. I attach pictures of current setup. Best regards

In classic Step7 V5.x you cannot view the online values of strings in the datablock view. You have to do this for example in variable table. If your string starts at DB100.DBX100.0 for example, then you add DB100.DBB100 with view type HEX (this is the maximum stringlength e.g. 16#FE for 254 length), then DB100.DBB101 also in HEX (this is the acutal length of the string), and then DB100.DBD102 to whatever you need with view type CHAR. This are the actual chars in the string, but valid chars are the...

Hello. I use NetToPLCSim v 1-2-4-0 for communication between WinCC advanced V18 and plc317-2 pn/dp. Everything works. But string type variables are not written to the data block. I tried both the script and the built-in commands WinCC. Nothing just happens. String variables contain 254 bits. Tell me, is the problem on the NetToPLCSim side or can this be solved?

old. but if anyone still uses... you can set a virtual network adapter as the same IP address as your simulated PLC and that will make it work, you can now ping the PLC and also connect to it from other sources such as visual studio etc.

Hi, I don't use this way usually, but if I remember correctly, there were some problems if you want to use all of the test and installation functions. But simple downloading of blocks (not in the PCS7 or CFC environment) should work I'd say.

Hello, Is it possible to use NetToPLCSim to download from STEP7 to PLCSIM on a different machine within the same subnet? I got 2 machines that have PLCSim running and WinCC for testing, whenever I change anything in the PCL program on my PC (with STEP7) I have to copy PLCSim file to other machines and restart their PLCSim, which quite cumbersome. Downloading remotely from STEP7 on my PC to PLCSim on other machines would be very helpful. Best regards, BIAS

Hi Massimo, are you trying the ping from the same machine where Nettoplcsim is running on (pinging localhost)? It seems that you are only connected to WLAN interface. Disconnect WLAN and connect the LAN interface to any switch or router. If you want to use the symbolic driver in Intouch OI, then from my last tests some years ago they weren't able to connect to Plcsim via Nettoplcsim. Also they don't support some old variants of the S7-1200. I suppose they have done their reverse engineering of the...

Hello Piotr, Nettoplcsim uses an existing network interface. It does not add something like an IP address itself. Means if the Scada should reach the PLC under 10.0.0.20, then you should add this address to the network interface where Plcsim and Nettoplcsim is running on (as you asked, they must be the same). If you are using the browse button beside the network address (with the "..."), you should be able to find this address. If you don't find this address, in 99% it wont work (1% is for special...

Hi Thomas, Thank you for providing the insights. Granting users the rights to manage system services is viable solution for the application to work smoothly. Nevertheless, you have also pointed out packaging Nettoplcsim into a install routine and grating it the admin rights, as are not much aware of this. We are trying to request for the system services permissions. Once again we are very much Thankful for your prompt support.
-
The admin rights are only neccessary, because Nettoplcsim needs access to control the system services, to start / stop the Siemens service which blocks the port 102. Your administrator give the user without general admin right, at least the rights to access the system services. https://learn.microsoft.com/en-us/troubleshoot/windows-server/windows-security/grant-users-rights-manage-services I don't see any other workaround with the current version.

I'm using Nettoplcsim successfully together with TIA V18. Only make sure you start your simulation setup in this order: After PC start, before starting any Siemens application, start Nettoplcsim with admin rights and let it capture the TCP Port 102. Let Nettoplcsim in this state, with no configuration Start Siemens Software, start Plcsim, load program into Plcsim Configure Nettoplcsim, and start the Nettoplcsim server Make your tests

Are you using the current S7online version of nettoplcsim, or the old S7ProSim variant 0.7.2? The S7ProSim variant doesn't allow area code 0x80. But if you write to an input 0x81, I'm using the S7ProSim method "WriteInputPoint()", which does also write to the periphery, if I understand the documentation correctly. The same with reading outputs with 0x82 where im using the method ReadOutputPoint()". When I'm adding the area code 0x80, my idea was to use ReadOutputImage / WriteInputImage, but I suspect...

Mikel Ayani posted a comment on discussion Help
Hi Thomas, We did try using 0x80 code but we get error responses even if we try to just write to inputs and read on outputs. We are using our code against PLCSim... We also realized that there is no different code for inputs and outputs ;) Did you managed to read or write with code 0x80?
-
As I just discovered, the S7 protocol doesn't differ between addressing peripheral inputs and outputs. Theres only one code 0x80 for periphery, it's the same as the area for an ANY-pointer in a S7 program. For example if you address in WinCC flexible PIW100 and PQW100, on the network the addresses are the same. I haven't a S7 with periphery for testing what value you'll get, if you have both addresses in your hardware configuration (PIW100 for an analog in, and PQW100 for an analog out).
-
Mikel, as I'm just working on the old version which used the S7ProSim interface, I can add this feature too, if you are ok with some limitations of the old version. Like it's not responding to all SZL requests as the new version does. And S7ProSim is limited, that peripheral inputs can only be written, and peripheral outputs only be read. And you can't access single bits, the smallest unit is 1 byte in this area. And S7ProSim is rather slow. Every method call on S7ProSim takes about 0,7 ms. For example...

I think I can add this feature to the old version. I'd add to the GUI an entry field where you can enter the Plcsim instance number to connect to, and an entry for the IP address where the server should start on. Then you can add multiple IP addresses to your network interface, and connect instance 1 to one ip, and so on. You have to start Nettoplcsim for each Plcsim instance. I won't do any further refinement on the old version. I'd would be better to use especially the network part from the new...

Dear Thomas, This topic follows this previous discussion ealier this year. After several successful uses of this new/old build above, we would now need another feature, that you added since then in the current version of NetToPLCsim: *** Allow multiple connections** We found a litteral explanation in the 0.7.2 documentation, confirming that it was not featured at that time (see attachment). Do you believe that this would be possible to allow multiple connections to the "nettoplcsim-0-7-2_x86" version?...
-
Thanks for your answers Thomas! We need to figure out another way to deal with that PLC code then.
-
If adding this, then to the old version. For the S7ProSim version Nettoplcsim needed to implement the S7 protocol completely, to pass the request to the S7ProSim Interface. The current S7online versions in general doesn't know anything of the protocol, it extracts the S7 part from the Iso-On-TCP layer and passes the data into S7online (with some extras). The manual only says that you can start multiple instances of Plcsim, but Nettoplcsim connects to the first started. The problem is, the instances...

It's possible, but not with the current Nettoplcsim version. Plcsim for S7-300/400 has an API (ProSim), where you can access or simulate peripheral IO. In Nettoplcsim versions before v0.9 I was using this interface. But the interface is rather slow compared to the S7online interface I'm using now. I don't know if I implemented accessing the peripheral data in the network part of these old versions. But be aware that the old Plcsim didn't support Profinet IO, you had to modify the hardware configuration...

Mikel Ayani posted a comment on discussion Help
Hi, We have a project where the PLC code uses DPRD_DAT and DPWR_DAT to move data from peripheral IOs to a Data structure in a DB. he peripheral IOs are in this case Profinet servo data. We are trying to validate the PLC code against an emulation model, but we have never read and write to ":P" addresses. When it comes to IOs, we usually disable the cards from the scan cycle and write directly into I and O memory. The question is, is it possible to write in peripheral memory? what about if we use PLCSim...

Hi, you must distinguish between what Plcsim supports, and what Nettoplcsim supports. Which functions are supported by Plcsim (for S7-300/400) are described in the operationg manual of Plcsim. In detail for communication, Plcsim (for S7-300/400) supports Put/Get communication between two simulated instances, but you have to use the SFB14/SFB15 blocks and not the FBs for Put/Get from the library. If you have a S7-400, then you would already using the SFBs and needs nothing to be modified for Plcsim....

Hi all, I have the following scenario: - S7-1500 x1 - S7-400 (step 7) x 2 1500 must be able to communicate with both 400 using both bsend/breceive and put/get so far i was able to set up a communication betwen 1500 and one instance of 400 using only put/get. After adding the second plcsim instance and configuring everything the call which is supposed to get data from second instance keeps pulling data from first instance. therefore i'd like to ask: - is it possible to have more than 2 plc's (Step7...

Dear Thomas, After several successful uses of this new/old build above, we would now need another feature, that you added since then in the current version of NetToPLCsim: * Allow multiple connections We found a litteral explanation in the 0.7.2 documentation, confirming that it was not featured at that time (see attachment). Do you believe that this would be possible to allow multiple connections to the "nettoplcsim-0-7-2_x86" version? Or rather reimplement ProSim into the current one? Thanks a...

I'd say, the settings are ok and it should work. Are both programs (dopsoft and Plcsim/Nettoplcsim) running on the same machine, or in different machines? If different machines, try if you can ping the 192.168.0.45. And check if the port 102 is not blocked by any firewall.

First make sure, you start the programs on your Step 7 station in this order: After PC start, before starting any Siemens application, start Nettoplcsim with admin rights and let it capture the TCP Port 102. Let Nettoplcsim in this state, with no configuration Start Siemens Software, start Plcsim, load program into Plcsim Configure Nettoplcsim, and start the Nettoplcsim server Make your tests If this still doesn't work, please give more informations about the IP addresses you are using. Remember,...

I know this thread is a little old but I have started experimenting with various setups for System Platform to talk to PLCSim on another box. Right now where is what I have working.. YMMV Object (host1) --> DDESL Object (Host1) --> OI Gateway OPCUA Client (Host1) --> TANI OPC Server (Host2) --> NetToPLCSIM (Host2) --> PLCSim (Host2) The little piece of magic here is TANI. You can run it for free for up to 72 hours and its crazy easy and flexible. Kepware would likely do just as well. I'm running...

Confirming that fixed it! Thanks so much for your assistance.

Hi, try starting Nettoplcsim first, before starting any Siemens software. This order: After PC start, before starting any Siemens application, start Nettoplcsim with admin rights and let it capture the TCP Port 102.

(possible duplicate topic as I accidentally sent email from non-registered account) Very much a noob with Siemens so I am hopeful I'm making a silly mistake. Here is my basic workflow Create simple program in TIAPortal V18, running on Windows Server 2022 21H2 From the PLC Device, Start Simulation Server Download to the PLCSim (v18) successfully Start NetToPLCSim as administrator Get the prompt about Port102 and the 'SIMATIC S7DOS Help Service' 's7oiehsx64' Answer yes to allow it to shut down the...

OS Server terminalbus should have 192.168.251.10. The other settings are ok for me. Can you ping 192.168.250.101 from the OS server? And doese the browse dialog in Nettoplcsim for the Network interface find the interface with 192.168.250.101? And make sure that you have set the connection type between OS and Plc to TCP/IP, an Iso connection won't work with Nettoplcsim.

Hello, I need help using nettoplcsim. I want to simulate PCS7 OS Server which is located on a different Virtual machine than the ES. In principle, i have two virtual networks PlantBus on ES:192.168.250.5 TerminalBus on ES: 192.168.251.5 The CPU address is set to 192.168.250.101 and i can sucessfully download and go online with plc on the ES. However, the there is no communication between the plcsim on ES and the OS server. i followed the procedures according to the manual. The network address on...
