Build Action Field

The Action Builder is a guided, click-based interface that helps you construct action expressions without manually typing formulas. It is used to populate the Success Action and Fail Action fields in Algorithm Design.

:gear: Overview

An action expression defines what the system should do when a process step succeeds or fails. In a pharmaceutical context, actions typically capture instrument readings, record operator inputs, or set values that drive downstream process behavior.

An action expression follows the pattern:

Variable(s) = Instrument/Value

For example: RecordedTemp = TIT_01 or Volume1, Volume2 = FI_01

Pharma example: During a CIP (Clean-in-Place) cycle, the success action for a supply valve step might be:

CIP_SupplyValveOpen = XV_CIP_01

This records the confirmed position of the CIP supply valve into a variable for traceability, ensuring the valve opened before chemical flow begins.

:desktop_computer: Window Layout

The Action Builder window is divided into five areas:

Area

Purpose

Selection Area

Click to select Variables and an Instrument

Edit Area

Two text boxes showing current selections — editable for custom values

Logical Operators

AND button to combine multiple atomic assignments

Final Formula

Live preview of the complete expression being built

Commit Area

"Insert Action" to apply, or "Cancel" to abort

:footprints: How to Use

Building a Simple Action

Step

Action

Result

1

Click one or more Variables in the Selection Area

Variables appear in the first Edit box (e.g., RecordedTemp)

2

Click an Instrument in the Selection Area

Instrument appears in the second Edit box (e.g., TIT_01)

3

Review the Final Formula at the bottom

Shows the complete expression (e.g., RecordedTemp = TIT_01)

4

Click "Insert Action"

The expression is inserted into the action field

Using Custom Values

Instead of clicking an Instrument, you can type directly in the Edit Area. This is useful for:

  • Capturing operator input: type operator input in the second box

  • Setting a static value: type 34l or 100°C in the second box

  • Using calculations: type any custom text

Example: Volume1 = operator input

Building Complex Actions

To combine multiple assignments:

Step

Action

1

Build your first assignment (e.g., RecordedTemp = TIT_01)

2

Click AND in the Logical Operators area

3

The first formula is saved, and the Selection/Edit Areas reset

4

Build your second assignment (e.g., RecordedPressure = PIT_01)

5

The Final Formula shows: (RecordedTemp = TIT_01) AND (RecordedPressure = PIT_01)

Tip: Parentheses are added automatically. Uncheck the parentheses checkbox to disable them.

:test_tube: Pharma Example Walkthrough

Scenario: You are configuring a CIP supply step. When the step succeeds, you want to record the CIP supply valve position and the supply-side temperature for batch documentation.

  1. Select variable CIP_SupplyValvePos

  2. Select instrument XV_CIP_01 (the CIP supply valve)

  3. Click AND

  4. Select variable CIP_SupplyTemp

  5. Select instrument TIT_CIP_01 (the CIP supply temperature transmitter)

  6. Final formula reads: (CIP_SupplyValvePos = XV_CIP_01) AND (CIP_SupplyTemp = TIT_CIP_01)

  7. Click "Insert Action"

This ensures that every time the CIP supply step completes, both the valve confirmation and the supply temperature are captured for the batch record.

:bulb: Tips

  • The Final Formula area is directly editable for manual adjustments

  • Multiple variables can be assigned the same instrument reading at once

  • Use custom text in the Edit Area for values that are not in the Selection lists

  • Actions are part of the Algorithm Design workflow — they appear in each step of the SFC Editor as well
