DSC Module Run-Time System

[msad66]

Hi,

I have used “Enable Value Change Notifications VI” and “Request Value Change Notifications VI” in my application.

I read the following link:

Since I do not use any of the following components I am wondering if I need “DSC Module Run-Time System” for the stand-alone application.

• Data logging (Citadel)
• Alarm & event logging (SQL Server Express)
• Alarm Service
• I/O Servers
• EPICS
• OPC
• Data Set
• Modbus
• Custom VI
• NI OPC Servers

My stand-alone application does not work and I do not know there is something wrong in the “Build Specifications” setting or I must have “DSC Module Run-Time System”.

Regards

msad66,

Yes, you will need the DSC Run-Time, as those VIs are part of the DSC module.

Thanks OlliesCamel

I just want to trigger an event structure by changing a shared variable value and I do not need any other feature of DSC module. Since I do not have DSC RTS, is there an alternative method to do that without using the mentioned VIs? Is there any invoke node or something with the same functionality?

msad66,

Unfortuantely there are no direct methods I am aware of, but could you describe your application in a bit more detail? There might be other solutions depending on what your end goal is.

Thanks OlliesCamel and excuse me for this late response.

My problem was solved. I added the “DSC module run-time” to the installer but I forgot to add “NI variable engine”. Unfortunately this additional installer has not been added automatically.
