T4a recipe

[Adrian]

Hi,
I've converted an old e410 project to T4a and I'm stuck with a couple of things.
1. The e410 had an Ascii box that displayed the recipe name in use.
2. The e410 recipe could be remotely changed from I/0 on the plc or a network signal through the PLC etc.

How can i get these to work on the t4a???

please speak in plain english, I'm only pretending to be a controls expert, I prefer mechanical things!!

Cheers

Hello there,

There is a special System Tag ( Tags -> Add tag -> System Tag ) which directly displays the recipe name when attached to a Label or AnalogNumeric element set to string on a screen.

As for the remote change of the recipe, im not certain what you mean? This part will require a Script to be written.

Hi Derkins, have there been any reported issues with the special System Tag? I tried doing what you suggest but it still didn't display the recipe name.

Thanks for the reply, that's sorted the current recipe display...cheers.
When we used the E410 HMI's the recipe could be remotely changed from the PLC, I cannot see how to do this with the IX screen???

To change the recipe using screen and touch input:

Create a button. Go to properties and in the action tab select Recipe -> Load recipe.

When you press the button in runtime, a window will pop-out where you'll be able to select what recipe to load.

In addition you can also directly attach a recipe to a button and skip the selection.


To change the recipe using some PLC input :

Write a script and add an event

Code: Select all

void Script1_Created(System.Object sender, System.EventArgs e)
{
	Globals.Tags.recipeTag.ValueChange += RecipeSelection;
}

Code: Select all

private void RecipeSelection(System.Object sender, System.EventArgs e)
{
	switch((int)Globals.Tags.recipeTag.Value)
	{
		case 1:
			recipe.LoadRecipe(RecipeName1);
			break;
		case 2:
			recipe.LoadRecipe(RecipeName2);
			break;
	}
}

I would advise you to go through Beijers' iX developer video course and refer to the manuals in the future.
