Production Step Types

Production Step Types

You are here:

Tascus production sequences are built using ‘Steps’. Each step type performs a different function from displaying work instructions to operators, to capturing shop floor data to performing quality inspections.

Display Work Instruction

Display Work Instruction will display a media file and a list of materials, tooling, health & safety and reference documents to a production operator.


In the sequence editor, it looks like this:


Media -Use this area of the editor to define which images, videos of PDFs to display visual work instructions to the operator.

Path – This specifies the path to the media file to display. This can be a jpeg, png, HTML, PDF or MPEG video.

Page – This is used when displaying PDF’s, this specifies which page of the PDF to display.

Edit – This opens up an image editor window which you can use to combine multiple images and markup existing images.

Text Instructions – Instructions are displayed on the right-hand side of the screen in a table format for operators.

Category – Allows you to select which group to display the work instruction information. Categories include:

  • Materials
  • Operations
  • Health & Safety
  • Reference Documents

Pre Conditions – This allows you to conditionally display a material, operation work instruction line based on product properties.

Symbol – Allows you to define a symbol to display next to the line of the work instruction.

Options for Displaying Text Work Instructions – A good option for displaying simple text instructions is the Operator Message field of the sequence editor. This text message will be displayed in the bottom status bar.

However for longer text instructions, or when more text formatting is required, it is best to leave the Operator Message field blank and use the Edit button to build formatted text instructions within the Display Work Instruction step.


Record Text

Record Text enables you to present a text entry box to an operator through which he can type in free text, or select from a drop-down list of options.

Free Text Entry Mode

The operator will be prompted with a text box to complete in the bottom data entry bar.

When configuring this step in the sequence editor, all you need to enter is the Operator Message to Display. This will be the message displayed above the text box that the operator completes when a sequence runs.

Drop Down List Mode

To configure this step in a drop-down list mode, you would need to populate the Text Options box with:


Scan Part

Scan Part enables you to record component part numbers using a barcode or keyboard input, it also allows you to check if the operator has selected the correct component, and if this has already been used in production.

In the sequence editor, it looks like this:




Barcode To Match – If this field contains a value, the step will only Pass if it finds a match in the value entered by the operator. If it is empty, the step will simply record whatever value the operator enters.

Quantity To Scan – This enables you to specify multiple components to be scanned in one step.

Query Database for Passed Operation – This can be used with subassemblies built using Tascus to check that an operation has been completed.

Operation To Match – If the above option is used, this specifies which operation to search for.

Check for Unique Part – This is an additional check on subassembly builds to ensure that a component is not scanned more than once.


Manual Measure

This step enables an operator to enter a numeric value and have that recorded against test limits.

In the sequence editor, it looks like this:

Measurement Name – Defines the text that is displayed above the numeric input box.

Units – This is what is displayed to the right of the numeric input box.

Low Limit – The lower numeric limit

High Limit – The upper numeric limit

Show Limits – Defines whether the limits are displayed to the operator when the production sequence runs.



This step allows you to perform a mathematical calculation using values entered into Tascus in previous steps.

To configure this in the sequence editor, you must select which measurements to use and enter a formula.

Use the drop-down lists to select inputs a,b,c & d for the calculation, then enter a formula. The above example shows a formula to multiply inputs a & b: a*b.

To validate your formula, and to edit more complex formulas, click on the Edit button to open the Calculation Editor.

The calculation editor allows you to build formulas on the right-hand side, then test a calculation by entering values for a,b,c & d, on the right-hand side.


Capture Image

This step allows you to capture an image using a camera connected to the station computer.

When the step runs, it will display a feed from the camera in the top right corner. When you press Capture Image the current image from the camera will be copied over to the main screen.

To configure this step in a sequence, you just need to specify a name to give the image when it is saved. You can also add text instructions to aid in taking the image.


Upload Document

This step allows you to upload a document to the Tascus report directory for each unique serial number product.

When the step runs, the operator will be prompted to browse to upload a file. This will then be copied into the data directory for the product & serial being built.

To add this step to a sequence, you need to specify an Operator Message to Display to guide the operator which type of document to upload. Then you need to specify the Document Name – this will be used to rename the document when it gets copied to the product data directory.



Pass/Fail Test

Pass/Fail Test enables you to prompt an operator to perform a test and say if it’s Passed or Failed.

On the sequence editor, it looks like this:

Test Instructions – This is the message that is displayed to the operator, above Pass & Fail buttons.


QA Approval

This step displays a box at which an operator or supervisor must log in again to confirm that a process has been completed. At this stage the inspector can use the View Report button to view the entire production report for this product, to review all results.

In the sequence editor, it looks like this:

QA Approval Message – This is the message displayed at the login prompt box.


Sequence Call

This step allows you to call another sequence. This is useful when trying to make your production sequences more modular.

This also affects how the production sequence is displayed on the Process List screen. Because the above sequence is split into subsequences, it is shown on the Process List as a nested sequence, which you can show and hide.
