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...

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...

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.

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...

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. Maybe it would work Nettoplcsim is packed into an...

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
