For instance FIC045 means it is the Flow Indicating Controller in control loop 045.
This is followed by loop number, which is unique to that loop. The first identification letter is for the measured value, the second is a modifier, 3rd indicates passive/readout function, 4th - active/output function, and the 5th is the function modifier. The identifications consist of up to 5 letters.

Identification and reference designation īased on STANDARD ANSI/ ISA S5.1 and ISO 14617-6, the P&ID is used for the identification of measurements within the process. P&IDs form the basis for the live mimic diagrams displayed on graphical user interfaces of large industrial control systems such as SCADA and distributed control systems. They are also vital in enabling development of Modifications are red-penned onto the diagrams and are vital records of the current plant design. P&IDs also play a significant role in the maintenance and modification of the process after initial build. To do this, it is critical to demonstrate the physical sequence of equipment and systems, as well as how these systems connect. During the design stage, the diagram also provides the basis for the development of system control schemes, allowing for further safety and operational investigations, such as a Hazard and operability study (HAZOP). P&IDs are originally drawn up at the design stage from a combination of process flow sheet data, the mechanical process equipment design, and the instrumentation engineering design.

In the process industry, a standard set of symbols is used to prepare drawings of processes.
