As Transistor said, the native Ignition Logix driver talks to Control Logix PLCs. Just be sure you study the best practices for communicating to Logix PLCs in regards to AOIs (avoid direct reference), UDTs, Tag Groups, et al.
Also, if this is a one off replacement, you may want to consider an Ignition Edge setup (2 clients) instead of a full blown Ignition install. Depends on what the future expansion plans would be.
