I would like to know if it's possible to setup a Siemens OPC server without being connected to any PLC. Would there be a simulations mode. I have the following software Simatic NET IE SOFTNET-S7 Lean. I'm not sure if I setup correctly see attached pictures. I beleive I can see the Siemens OPC server and another OPC server already installed in the network Factory Talk Gateway server using OPC scout. For now the Siemens configuration software and opc scout is on the same computer as the server. I would like to see the OPC server from a remote computer using another OPC client software.

Difficult to see anything since you have downscaled everything.
Use GIFs at full size, but with small windows. This is the best way.

Anyway.

The configuration isnt finished.
In HW Config, you must attach the IE General to an ethernet network, and set its IP address.
In NetPro you must setup an OPC Connection.
Then you must either download to the Station Configurator, or load the .xdb file in the Station Configurator.

As far as I know, there is no simulation mode of the OPC Server in Simatic Net.
But there are several test OPC servers out there:

I missed this bit:
I would like to see the OPC server from a remote computer using another OPC client software.
That can be done by setting up DCOM. This means that the remote PC must be granted permission to access the local PC. This is not so trivial. Search for "OPC DCOM" on Siemens support site if you need to do it this way.

There is specialised software that makes this much easier. Google for "OPC bridge" or "OPC Gateway".
