Controls Standards

[tvich]

Can anyone out there help me recall the organization that has a standardized controls approach to a process. ??S90 or G?? Requlations??? It's like the ISO9000 in the controls world. And it pertains to how P&ID's are labelled, broken down, and then translated into a PLC program, to summarize it VERY loosely.

Thanks.

NFPA 79 industrial Controls in the US
ISA 5.1 - 5.5 for P&ID symbols, diagramming and loops.

The ISA part 5 (?) covers various aspects:

5.1 Instrumentation Symbols & Identification
5.2 Binary Logic Diagrams for Process Operations
5.3 Graphic Symbols for DCS
5.4 Instrument Loop Diagrams
5.5 Graphic Symbols for Process Displays

like Gerry says.
