5. 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 ? ?

6. Connectivity for PA Systems – Confusion or Opportunity IFPAC 2001 Food for Thought: The Process Analytics Community 1M $? Convene a Process Analytics “Connectivity Focus Group” (Sponsored by CPAC or MCEC or ISA AD?) Representation: End-users/Analyzer Vendors Develop a consensus about Proprietary vs Open Model (POM) (Learn from FF and OPCF?) - Vendor Issue Agree on the System Functionality Requirements - End-User Issue Understand the possible range of compatible/incompatible solutions (Hardware & Software) Propose a plan to develop a connectivity/infrastructure model (Include industry acceptance) Continue?
