DSC Citadel

[samerham1]

Hello,

i am working with DCS module, citadel and OPC servers

i need to know how could i have, in a VI:

- the list of all available OPC servers and by clicking on each OPC server it should browse all available variables

- then i should be able to select the variables that i need to trace, define the libraries and the path in which i want to archive each variable

- then by pressing on OK button the variables will begin to be traced in the location defined

- And if it is possible to define the frequency and the scale of each variable

In resume, i want to do an Interface in a VI in which i can choose all the variables that i need to archive without using the project explorator (which browses the servers and variables).


How could i do that ? could you help me please ?

Hi,

Does it mean a DCS or the LV DSC module?

Please be clear.

I think there is no VI that will list out all the available OPC servers & the shared variables, that you get to see in the NI Variable Manager.

Hi,

it is indeed the LV DSC module.

i need to list out all OPC available server programatically in a VI without needing the variable manager.

are u sure that i can't ?

I think you can programatically get only the Shared Variables, not the OPC servers.

Yes, it is possible. I've been successful in my projects in accomplishing this.
