Using the Parameter Table

New This Feature Was Added In HELIO 26.2.0

The Parameter Table, accessible from the Recipe Management Page, gives you full access to all parameters of a recipe — listed in a searchable table, with the current PLC value shown right next to the stored recipe value.

It's a useful tool during machine development and commissioning, or for service specialists who need to quickly scan and filter through every parameter. For smaller HMIs with only a few parameters per recipe, it can even work as the parameter editing page itself — fast to set up, and simple enough to hand to operators too.

1. Enable the Parameter Table​

  1. Enable the Parameter Table

Select your Recipe Management Page and expand the Parameter Table property group in the properties panel. Set Enable to true.

This adds an Edit Recipe button next to Load Recipe in the recipe detail view.

Tip: Enable This Feature Using Roles

Since Enable is a Dynamic Property you can also switch it to Restrict To Users in order to only show the Edit Recipe button to specific user roles.

2. Edit Parameters in the Table​

  1. Open a Recipe for Editing

Use the HMI Preview Panel and switch to Test mode. Select a recipe from the list to open its detail view, then click Edit Recipe.

  1. Compare and Edit Values

Every parameter of the recipe is listed with its Path, its stored Value, and the current PLC Value. Edit a value directly in the table — deviations between the recipe and the PLC are easy to spot at a glance. Use the Search field to find specific parameters in large recipes.

  1. Save Your Changes

Click Save Recipe to store your changes, or Cancel to discard them.

3. Handle Uninitialized Parameters​

Recipes evolve over the life of a machine — new parameters get added to a Recipe Type both during development and later, once it's already in the field.

  1. Add Parameters

Use the Data View or the Recipes View to add additional parameters to a Recipe Type.

The Data View can also be used to provide a fallback value for newly added parameters.

What Are Fallback Values?

If a recipe with an unset parameter is loaded onto the PLC — for example via Load Recipe — HELIO uses this fallback value automatically, without anyone having to open the Parameter Table first.

  1. Filter for Unset Parameters

When a new parameter is added to a Recipe Type after a recipe has already been saved, that recipe doesn't have a value for it yet.

If you open a recipe with missing parameters, HELIO shows an additional Unset Parameters filter. Switch to it to see only those parameters.

←→
  1. Initialize the Value

Click Initialize to add a value for this parameter to this recipe. If a fallback value has been configured, HELIO will use it. Otherwise, it defaults to a valid neutral value. After initialization, you can edit the value as you would with any other parameter.

Mission accomplished!

That's it — your operators can now edit recipe parameters right in the HMI.
