Need help with Siemens connection to ignition

Ignition
1

Looking for some help, i was task to get some out Older siemens plcs to communicate to Ignition. i personally haven't touched ignition much.
we have a s7 cpu 412-2 that i need to connect to our network somehow...
my question is that we already have a PC/HMI that connects with a USB a2 adapter to the line. is there a way to piggyback off the ethernet adapter on that pc to give access to ignition.

Let me know your thoughts or ideas.

Thanks,
Benjamin Sales

Natively from Ignition? Pretty sure not. Maybe there's a 3rd party OPC server that can do so.

I suggest for the old SIemens plc s7 300/400 without ethernet to use a product like that:

Hilscher: NL 50-MPI–S7-200/300/400 Ethernet programming connector

anyways the price is not distant to a native plc ethernet card ...
