  • Administration Guide: connect PI Data Archives, AF, PI Vision and hosts, set up scan automation and notifications, and keep PI Nexus+ running.
  • User Guide (this document): find unhealthy objects, investigate issues, follow dependencies and changes, and confirm repairs.
  • Reference (online only): the tables behind all three guides, such as defaults, states, issue catalogues, rights and ports, at https://www.software-athlete.com/pages/documentation-pi-nexus-reference.
