I have a Siemens 555 PLC, with a CTI 2572B Ethernet TCP/IP communications adapter in our plant that I would like to try and interface with Ignition.  
Is there an OPC-UA Server- Device, that I can select to configure for this setup?  
Thanks

KepServerEX has a Siemens TI Suite that works great with them.
