Mesta Automation A blog about WPF, C# and PLC software development
This is a tutorial on how to connecto to NetToPlcSim. The official site to download the program is here: http://nettoplcsim.sourceforge.net/
With NetToPLCSim you are able to connect your SCADA/HMI-systems via S7-communication to PLCSim over TCP/IP, and read/write data areas from your simulated PLC.
What do you need to connect:
1- PLCSim v 5.4
2- Ethernet cable plugged in (some peoples says this is needed)
3- Port 102 Opened (so exception in your firewall and shutdown s7oiehsx service (command line from start -> run : net stop s7oiehsx)
Let’s create a new project, add a s7 300-2DP (standard configuration) and an ethernet card CP-343-1.
Now the PC that is running Step 7 and PLCSim is the PLC, this means that PC and ethernet card must have the same IP Address and if you are communicating with another PC you have to set also the router address. In my project this is the configuration of ethernet card:
Set Pg/Pc interface on TCP/IP and check that plcSim is using TCP/IP too:
Save, Download and Close Hardware Configuration.
Create a program, download it and go online to check that everything is working with PLCSim (TCP/IP).
Then open NetToPLCSim, push Add button and configure the plc (pc):
If you are on testing in localhost you can also use this configuration:
If you did everything good you should see the plc when you browse for addresses; now press Start All and you are ready to use PLCSim with your SCADA.
You can download the sample for Step 7 v 5.5 here: https://www.mesta-automation.com/Downloads/Nettoplc.zip
Hi, What version of Simatic Manager you are used…?
Step7 v 5.5
how if use plc sim tia portal?
If you want to use the Plcsim for S7-300/400 in TIA-Portal, it should work with Nettoplcsim, as Plcsim is the same program as it was under Step 7 V5.x. The limitations of Nettoplcsim are existing furthermore (no programming functions possible, no block-messages, …)
If you want to use it with the simulator for S7-1200/1500, it is currently not working.
From http://sourceforge.net/p/nettoplcsim/discussion/912717/thread/cfc69c86/?limit=25#3cae
it works!
I used to connect PLCSIM with Javafx2 with example project here https://alexsentcha.wordpress.com/libnodave-exchange-data-with-siemens-plc-2/javafx-exchange-data-with-siemens-plc/
thank you
How can you configure citect scada installed in the same computer as step7 v5.5 to communicate with plcsim
You configure it the same way as you would configure it for a real S7 plc with an ethernet port. Just use 127.0.0.1 as Ip address, if you are running NetToPlcSim locally.
hi
Enter your comment here…Thanks for u quick reply.
please explain to me how to do it step by step. Thanks in advance .
Citect has a customer support, you should contact them. About NetToPlcSim, the article is clear enough.
Hello, can I use nettolcsim to communicate with iFix?
If it has a S7 TCP driver yes.
Hello ,
PLSIM only allows to have datas within PLC Simulation , while my PLC is connected to en engine with VPN and displays variable data in dynamic visualization.
If I connect my Vb app via Nettoplcsim, I could not have real data, would you have another solution ?
yes
Hi,
Can PLC Step 7 be connected with Citech SCADA through NetToPLCSim.??
Thanks,
Saptarshi.
Hi,
Can we connect Siemens Step 7 with Citect SCADA through NetToPLCSim.
Thanks,
Saptarshi
Thank a lot!
Hi Mesta,
Ethernet cable plugged in where?
Thanks
Hi Mesta,
Finally it works. Now i’m trying to read datablock from netToPlc. Any suggestion or just download th DB from step7 to Plcsim?
Thanks a lot !
using plcsim v18 with weintek simulation
Has anyone asked if the way the plcsim v18 is connected to the weintek simulation has changed as opposed to the old plcsim. Because doing everything according to the videos that are available and the order is the same everywhere, I get the error connecting from the weintek simulation. If anything, I use this order – I create a tia portal v18 project, add something, run a simulation. I start NetToPLC, disable the service as suggested by the program to free up port 102, and specify the ip from plcsim and my ip in the required locations. I’m starting the server. I’m creating a weintek project, adding an s7-1200/s7-1500, everything is similar to the guides and changing the ip to a personal one. I add objects to the project, but when I start the simulation, I get no connection.
