18. Connectivity for PA Systems – Confusion or Opportunity IFPAC 2001 The Process Analytics Community 1M $? Given the choices of: controller, server and workstation platforms communication protocols database options (short term and long term) security and controls needs (local & remote access) How do we develop and agree on industry guidelines for the analyzer connectivity infrastructure which will ensure plug-and-play compatibility for all analyzers? ? ? BIG QUESTION ? ?

19. Connectivity for PA Systems – Confusion or Opportunity IFPAC 2001 Considerations: The Process Analytics Community 1M $? Convene an Open Process Analytics “Forum” (Sponsored by CPAC or MCEC or ISA AD?) Develop a consensus about Proprietary vs Open Model (POM) (Learn from FF and OPCF?) Confirm challenges to achieve POM goals Establish a Workgroup to address each challenge (should NOT be a formal standardization effort) Issue Guidelines Keep Effort Evergreen
