Trying to debug a VBA script in FTV SE 9

so I am trying to figure out this syntax

Set Ingredient = Application.CreateTaggroup(Me.AreaName, 500)

Ingredient.add "[CompactLogix Processor]Ingredient_List"

Ingredient.Active = True

Set Tag1 = Ingredient.Item("{[CompactLogix Processor]Ingredient_List}")

So is [CompactLogix Processor] a tag group and
Ingredient_List a tag ?

or is

{[CompactLogix Processor]Ingredient_List}") a direct path to the Rslinx Enterprise topic

Ingredient --> Tag group
Tag1 --> FTV tag

CompactLogix_Processor ---> FTV shorcut to processor
Ingredient_List ---> PLC tag

First notice the [CompactLogix Processor]
has no underscore
Second, why do you need to touch the PLC shortcut
and not just reference the Tag in the FVT Database
directly


Ingredient --> Tag group
Tag1 --> FTV tag

CompactLogix_Processor ---> FTV shorcut to processor
Ingredient_List ---> PLC tag"



Set Ingredient = Application.CreateTaggroup(Me.AreaName, 500)
Ingredient.add "[CompactLogix Processor]Ingredient_List"

Ingredient.Active = True

Set Tag1 = Ingredient.Item("{[CompactLogix Processor]Ingredient_List}")

I see no reason it would not work like
Tag1 is a FTV Databse tag
Tag1.Value = 1.0
Tag1.Download

Sorry, I always put underscores instead of spaces and it's a harcoded habit in my brain (almost an OCD).

You can use HMI or PLC tags. Usually HMI tags have more delay than PLC tags.

Using HMI tags you'll have:

I'll test it later and give you some feedback.

The differences between HMI and PLC tags have been discussed before:

This is how I did it

Option Explicit
'Global declarations
Public MyTagGroup As TagGroup
____________________________________________________

Private Sub Display_AnimationStart()
Set MyTagGroup = Application.CreateTagGroup(Me.AreaName)
MyTagGroup.Add "Recipe\Currect_Recipe_Collector_Cnt"
MyTagGroup.Add ("Recipe\CheckBox_EB_P_CNTRL")
MyTagGroup.Add ("Recipe\Recipe_Index")
MyTagGroup.Add ("Recipe\Recipe1_Name")
MyTagGroup.Add ("Recipe\Recipe2_Name")
MyTagGroup.Add ("Recipe\Recipe3_Name")
MyTagGroup.Add ("Recipe\Recipe4_Name")
MyTagGroup.Add ("Recipe\Recipe5_Name")
MyTagGroup.Add ("Recipe\Recipe6_Name")
MyTagGroup.Add ("Recipe\Recipe7_Name")
MyTagGroup.Add ("Recipe\Recipe8_Name")
MyTagGroup.Add ("Recipe\Recipe9_Name")
MyTagGroup.Add ("Recipe\Recipe10_Name")
End Sub
_________________________________________________________

Private Sub Add_list()
Dim Recipe_Name As Tag
Dim Recipe_Index As Tag

Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe1_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe2_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe3_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe4_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe5_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe6_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe7_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe8_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe9_Name")
FormListBox.AddItem (Recipe_Name.Value)
Set Recipe_Name = MyTagGroup.Item("Recipe\Recipe10_Name")
FormListBox.AddItem (Recipe_Name.Value)

End Sub

It important to use the correct syntax
Ingredient.add "folder_name\Ingredient_List"
would be (Ingredient.add "folder_name\Ingredient_List")

Now you said reading directly from the PLC would be faster that
reading a database tag that already on poll, how is that ?
