List of tags...

[ScottyP]

Hi folks, when using EthernetIPforCLX.GetTagList - I get a lot of things which are not visible in the PLC tag list, and things which are the top level of an array, and not the members of the array. (MyFLoat[100] just comes out as MyFloat)

I only have controller-scoped tags and no program scoped ones, there are also lots of things like _DEFVAL_0000DEE etc, what are these and why do they show up when they aren't visible in the controller tag list in Studio?

The tag "MyFloat" is in fact just "MyFloat".  The tag name is not "MyFloat[100]".  You need to look at some additional properties of each tag that is returned.

Code: [Select]

Dim TagList() As AdvancedHMI.Drivers.CLXTag = EthernetIPforCLXCom1.GetTagList
MessageBox.Show(TagList(0).ArrayElements1)

The CIP object that returns the tag database contains other things as well.  In your example, __DEFVAL has to do with AOI definitions.

ScottyP, just so you are aware, there are also AHMI controls that get tag list and could be added to the project:
