P&IDs and Modules

A single AseptSoft Module can span across multiple P&ID drawings. This allows you to share the same Process Design, Algorithm Design, and Exports across all included P&IDs — ideal for plants where processes flow through multiple drawings.

🔄 How It Works

Concept

Description

🏗️ Host Project

Contains all P&ID drawings (.dwg files)

📦 AseptSoft Project

Includes all P&IDs from the Host Project

🧩 Module

Can be linked to one or more P&IDs from the project

Key benefit: When a module spans multiple P&IDs, changes made in one P&ID are instantly reflected in all other linked P&IDs.

🔗 Linking P&IDs to a Module

To add or remove P&IDs from a Module:

Step

Action

1

Open a P&ID drawing in AutoCAD

2

Go to the Home Ribbon and click "Share with other P&ID"

3

In the dialog that appears, check the modules you want this P&ID to participate in

4

The module now includes this P&ID — activate it from the ribbon to start working

Note: When you first link a P&ID to an existing module, you will see all the module's data (Processes, Steps, States, etc.) as they were last saved.

📋 What Gets Shared Across P&IDs

When multiple P&IDs are linked to the same module, the following are shared:

Shared Data

Description

🔄 Processes and Steps

All processes and their step definitions

📊 Module Data

States, Fluids, Parameters, Variables, Dialogs, Equipment Modules

⚙️ Algorithm Design

All conditions and transitions

🏷️ State assignments

Each P&ID has its own engineering items, but they all share the same step context

📤 Exports

Consolidated exports include data from all linked P&IDs

What Stays Per-P&ID

Each P&ID maintains its own:

  • Engineering Items (valves, instruments, etc.)

  • Connectors and piping layout

  • Notes and Trackers placed on that specific drawing

  • Fluidstream simulation visuals

🔄 Working with Shared Modules

Synchronization

Shared modules synchronize automatically. The following operations performed in one P&ID are immediately visible in all other linked P&IDs:

  • Creating, renaming, or deleting a Process

  • Switching the active Process or Step

  • Modifying condition data

  • Adding or changing Module Data (States, Parameters, etc.)

The Module Ribbon stays consistent as you navigate between P&IDs within the same module.

Open and Closed P&IDs

You do not need to have all linked P&IDs open at the same time:

P&ID State

Behavior

Open + Module activated

Fully visible — all data available and editable

Open + Module not activated

P&ID is open but not participating in the shared module

Closed

Data from this P&ID is not visible in other linked P&IDs

Important: When a linked P&ID is closed, its engineering items will not appear in exports, the Live Viewer, Find and Replace, or Intelligent Suggestions.

✅ Activation Requirement

Simply having a P&ID open is not enough — you must also activate the shared module from within that P&ID for it to participate. To activate:

  1. Open the P&ID drawing

  2. Select the shared module from the Home Ribbon module gallery

🏭 How To: Set Up a Multi-P&ID Module

Follow these steps to create a module that spans multiple P&ID drawings:

Step

Action

Details

1

Open your first P&ID drawing

This is where you will create the module

2

Create a new module

Use the Home Ribbon > New Module

3

Define your Module Data

Create States, Fluids, and Parameters in the Module Data window

4

Open your second P&ID drawing

The drawing must be in the same Host Project

5

Link the second P&ID to the module

Click "Share with other P&ID" in the Home Ribbon and check the module

6

Activate the module in the second P&ID

Select the module from the module gallery

7

Start assigning states

Both P&IDs now share the same processes and steps

💊 Pharma Example: Multi-P&ID CIP Process

Consider a pharmaceutical CIP (Clean-In-Place) system with two P&ID drawings linked to the same module:

PID-101 (CIP Supply / Tank Area)

PID-102 (CIP Return / Pipe Network)

Engineering Items

CIP Tank T-101, Supply Valve V-101, Dosing Valve V-102, Temperature Transmitter TT-101

Return Valve V-201, CIP Pump P-201, Heat Exchanger HX-201, Conductivity Transmitter CT-201

Shared Process

CIP Alkaline Wash

CIP Alkaline Wash

Step 1: Pre-Rinse

V-101 = Open, V-102 = Closed, TT-101 = Monitoring

V-201 = Open, P-201 = Running, HX-201 = Bypassed

Step 2: NaOH Circulation

V-101 = Open, V-102 = Open (dosing NaOH), TT-101 = Monitoring (target 75°C)

V-201 = Open, P-201 = Running, HX-201 = Heating, CT-201 = Monitoring

Step 3: WFI Rinse

V-101 = Open, V-102 = Closed, TT-101 = Monitoring

V-201 = Open, P-201 = Running, HX-201 = Bypassed, CT-201 = Monitoring (target < 10 µS/cm)

Step 4: Drain

V-101 = Closed, V-102 = Closed

V-201 = Open, P-201 = Off

Both P&IDs share the same "CIP Alkaline Wash" process and steps, but each has its own set of engineering items with independent state assignments. The fluidstream simulation shows WFI and NaOH flowing between the drawings through Off-Page Connectors.
