Hi,
Unfortunately I'm not aware of any open source PLC simulators that support the S7 comm protocol.
If you are familiar with C++ you can use the Snap7 library, which also implements the server part of the protocol. This library allows you to create a simple server application that can be used with the Kura S7 driver.
There is also an example for this use case in the source package.
Or, as an alternative, you can use a commercial PLC simulator.

Regards,
Nicola

in the source package I have found the following:

org.eclipse.kura.drivers.s7plc
org.eclipse.kura.drivers.s7plc.localization
org.eclipse.kura.drivers.s7plc.provider

I was referring to the Snap7 source package, obtainable from here:
https://sourceforge.net/projects/snap7/files/1.4.2/
You can have a look at snap7-full-1.4.2/examples/cpp/server.cpp.
The library documentation is available at snap7-full-1.4.2/doc/Snap7-refman.pdf
Under snap7-full-1.4.2/examples you can also find examples covering the server part written in other languages.

Regards,
Nicola
