PID Components

PID Components are the building blocks that AseptSoft recognizes on your P&ID drawings. When a module is opened, AseptSoft scans the drawing and identifies components based on the classification rules configured during First Time Setup.

Whether you are modeling a CIP skid, a WFI distribution loop, or a full SIP sequence, every valve, instrument, and source on your P&ID is represented as a PID Component.

🔍 How Components Are Detected

AseptSoft uses a classification system to identify components on P&ID drawings. For the complete reference on classification types, tokens, and the classification window, see the P&ID Components Classification page.

  1. Block references in the drawing are scanned

  2. Each block's class name is matched against the classification rules

  3. Based on the class type property, the block is assigned to the appropriate collection:

Classification Type

🏗️ Component Hierarchy

All PID Shape Components share a common hierarchy that determines their capabilities:

Level

Features

Used By

Base Item

Entity handle, loading state, secondary shapes

All components

Colorable Item

State assignment, color overruling, active state tracking

Engineering Items, Instruments, Sources

Valueable Item

Adds percentage value support (0–100 %)

Engineering Items (valves with modulating positions)


🎨 Color Overrule System

PID Components are colored automatically by AseptSoft's Color Overrule System, which uses a priority-based approach:

Priority

Scope

Description

3 (Highest)

Item State

Colors from assigned States (e.g., valve Open = green)

2

Fluid Stream

Colors from Fluidstream Simulations

1

Non-Fluid Gray

Gray coloring for pipes without active fluid flow

0 (Lowest)

Drawing-Wide

Base color overrides

The highest-priority scope with a registered color wins.

💊 Pharma example: During a CIP sequence, a butterfly valve (V-101) is assigned the "Open" state (green, priority 3). At the same time, the Fluidstream Simulation paints CIP Caustic (purple) through the downstream piping (priority 2). Because Item State has higher priority, V-101 stays green while the pipes turn purple.


🛠️ How To: Identify Components on a New Drawing

  1. Open or create a module for your P&ID drawing.

  2. Run First Time Setup to configure the classification rules.

  3. AseptSoft scans the drawing and populates the Valves, Instruments, Sources, Off-Page Connectors, and Block Valves collections.

  4. Verify detected components in the Module Ribbon panels.

  5. Assign States and run a Fluidstream Simulation to validate the setup.
