Johnson, PE, Control Systems EngineerThe P&ID is the most important project drawing and is developed by all disciplines working together, taking turns working on the drawing. It begins with the PFD to which piping process and instruments are added until it is complete. P&ID Process (Piping) & Instrument DrawingChapter 2

Piping & Instrument Drawing ImportanceP&IDDescriptionELC-213Piping & Instrument Drawing ImportanceThe Piping (sometimes referred to as Process) and Instrumentation Drawing (P&ID) is the overall design document for a process plant. It defines, using symbols and word descriptions, the equipment, piping, and the instrumentation and control system. It is also the key to other documents. For example instrument tag numbers are shown on a P&ID. This tag number is the key to finding additional information about this device on many other documents. The same is true for line and equipment numbers.

P&ID DefinedP&ID DefELC-213P&ID DefinedLabThe acronym "P&ID" is widely understood within the process industries as the name for the principal document used to define a process - the equipment, piping and all monitoring and control components. The Automation, Systems and Instrumentation Dictionary, 4th edition's definition for a Piping and Instrumentation Drawing (P&ID) describes them. P&IDs show the interconnection of process equipment and the instrumentation used to control the process.There are several ISA standards to follow when developing a P&ID and the primary one id ANSI/ISA-5.1-2009 Instrument Symbols and Identification. This is the oracle for anyone documenting a control system

You must get familiar with all of the above in order to complete the labs in this course and you there will be many quiz questions that you must answer concerning this ISA Standard.
