Food for Thought:
• Convene a Process Analytics “Connectivity Focus Group”Convene a Process Analytics “Connectivity Focus Group”(Sponsored by CPAC or ISA AD?)(Sponsored by CPAC or ISA AD?)Representation: End-users/Analyzer VendorsRepresentation: 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?
