I don't know what may be the problem, but seems to me that the OPC server doesn't have an access to the PLC (the NetToPLCsim and the PLCsim). If you want to retrieve a list of OPC Unified Architecture servers registered on a local or remote computer, call the DiscoverServers method, passing it the name or address of the remote machine (use empty string for local. "Online: Connection could not be established the connection partner is not responding" OPC UA Local Discovery Server is a special OPC-UA service that provides information about other OPC-UA servers available. On the a right click on the index 125 of the Station configuration editor ( Stationmanager) and then on "diagnostics" I got the message: The OPC server and IE general that I use are the version 8.1.

In addition the following software will be needed in this Tutorial: NI OP Servers (Evaluation version. "Could not log off the proxy with index 125 from the SoftBus" LabVIEW Datalogging and Supervisory Control Module. In the Station Configuration manager I have message: When I start the OPCscout and try to run a OPC.SimaticNet server and a OPC UA server I got the messages (see an attachment).

In the library I created bound variables that are bound to the NI OPC tags and deployed them. Then with LabVIEW 2010, I opened a new project, opened a new IO Server and a library. I can see value changes in the inputs with the OPC Tester. NET 3.0) Option for OPCDA.NET Client Component. Then I got NI OPC server up and running and configured all inputs and a few bits as tags. On the first virtual machine I have a PLCsim and a NetToPLCsim, the PLCsim and the network have the same IP address and I have found the in the NetToPLCsim and have them started, the PG/PC interface is set to PLCsim TCP/IP. Cyberlogic DHX OPC Server Suite for Allen-Bradley (32-bit Windows) Cyberlogic DHX OPC Server Suite for Allen-Bradley (64-bit Windows) DANW-Xi Express Interface (OPC. Hi, I did the configuration you explained using two virtual machines and I can ping one from the another. In that document I use the option to add a second IP address to your interface, but you can simply change the IP address.

I've written a document of how to setup a simulation with Simatic Net OPC server and Plcsim/Nettoplcsim (file SimaticNet-OPC-mit-Nettoplcsim.pdf), but it's only in german available: With OPC, your device-side server and application software can.

If in your example the computer with Plcsim/Nettoplcsim has the IP 192.168.1.4, then in your NetPro Setup, the PLC which is the destination of the S7connection you hav configured must have the IP 192.168.1.4. If you want to connect the Simatic Net OPC server to Plcsim/Nettoplcsim, you must run them on different computers (or use a virtual machine). I don't know why, but the Siemens OPC server does not like this, with other OPC servers this is no problem.

Running Simatic.Net OPC server and Plcsim/Nettoplcsim on the same PC does not work, as the OPC server then has to connect to the machine where it is running (localhost).
