If you know how to use the IO tags once you have created them, i.e. in the control module, then you already know how to create tags.

Any parameter within a module is addressable in the HMI, in other words, these parameters are the tags.  Create a new module, add a parameter to it, assign it to a cont/workstation and download.  You can then point the HMI to that parameter (tag).  DVSYS.YOURMODULE/PARAMETER.F_CV (if float).

does that make sense?

Hey 

I am a student in my final year and am using DeltaV in my project 

I want to know how to create tags in the DeltaV system?

i am trying to create tags and use them later in the DeltaV Operate Configure HMI

I want to use these tags to store data that i am reading from OPC DataHub through Tunnel/mirror.

I know how to create tags for I/O but what i want to know is that , is it possible to create internal tags in DeltaV that are not associate with I/O?

Thanks
