Unable to connect to PLCSIM using FreeOPCUA client or even Ignition Scada

I had set the following configuration:
Set the PG/PC interface to PLCSIM.TCPIP.1
Set up PLC SIM, with OPC UA Server running and loaded the program
Set the ip address of network as the local ip adapter ( just connected two pc with ethernet cable to get this IP)
Set the simulation ip to the ip shown on the PLCSIM
Started the server
After all this I was unable to connect to the server by using FreeOPCUA client or even Ignition Scada
Hi,
Nettoplcsim with standard Plcsim does not support the simulation of the OPC-UA server on the CPU. You need Plcsim-Advanced for this, then you don't need Nettoplcsim at all.
Thanks Thomas!
It answers my question to a great extent. Currently I use a PLC to create a
opc ua server and using opc ua library on python to read the tags and write
to it. Is there a way to do the same using Nettosim and PLCSIM on tia
portal V17. If so then it would be a great benefit.
Also I wanted to understand the extent of support Nettosim offers to using
ignition Scada platform.
Thank you in advance.

I wouldn't say it's impossible to emulate an OPC-UA server, but it would have nothing to do with what Nettoplcsim is doing now. And the emulation would not have something to do with what you've configured inside TIA Portal. You could emulate this by setting up a software OPC-UA server like Simatic-Net, and let it connect to Nettoplcsim instead of a real Plc, and let your OPC-UA client connect to the Simaric-Net OPC-UA server instead of the Plc.
Thanks alot!
I will try to explore this more
