Siemens PCS7 and ISO-Protocol

I am interested in using the Ignition OPC-UA Server with a Siemens PCS7 system (CPU 416-DP and CPU 417 processors) that uses the ISO-Protocol on the system bus. (Our configuration is similar to the configuration in this link - in particular see step 4) : I have contacted other OPC Server vendors and their software will not work with the ISO-Protocol and MAC addressing. Their products only work with TCP/IP Ethernet. Can someone tell me if I can use Ignition’s OPC-UA server with only a MAC address? (No IP addresses are used on our system bus.)

No, our Siemens drivers only support the S7 protocol over TCP.
