DSC Module: Alarms & Events: How can I programmatically set the 'set user'?
Here is an example. Below is an image of one of the examples that comes with the DSC Module.
Notice how the 'Set User' column displays a value of (Nobody).
I can programatically adjust the alarm limits on shared variables via property nodes:
(see example
Dynamically Update Shared Variable Alarm Levels Using the DSC Module)
but not the Set User.
Thanks for the info. I had not discovered the Security dialog under the Options. However, now that I have delivered the first version of the software and have more time to play around, I have discovered the Account Domain Manager under Tools->Security, and that seems to be what I need. In the image below, I used the Example entitled 'DSC Dynamic Alarm Update' (available in Example Finder). But first, I created a local domain called 'Skelly', and logged in as a user named 'zimmer'. When the alarm came in, you can see that the set user is no longer 'Nobody'. So now, all I need to do is modify my startup VI, to have each operator log in (using the DSC Security VIs). That way I will have a record of which operator adjusted the valves & pumps. ( I write all commands going to control devices to a text shared variable which I log. I also have checked the option to Generate an event upon value change.)
