Hist alarm & events. vi

[Uttam Kotdiya]

OS Windows 2000
Software Labview 6.1
logos 4.4.0.15

I am not able to access the alarm data from the networked
PC. I am using Hist Alaram & Events vi and writing database path as
\\Udp-262\C\Program Files\National Instruments\LVDSC Run-Time System\data
but it return no alrams. Did I need to do something more to access the remote pc alaram tags. Or someone had seen this problem before.

This should work. However, the tricky part is the filter>process field, that needs to be not empty. The context help (CTRL+H) says about this control (filter>process😞
"Return only alarms generated by a specific process. If blank, the LabVIEW process on this computer is used. The format of this filter can be as follows:
* - match any computer and process
\\computer\* - match all processes from a particular computer
\\computer\process - match only a particular process from a particular computer"

If you set a * in this control, this should allow to retrieve data from e.g. \\remoteDSCPC\c\NI\LabVIEW 6.1\data folder.

Note: You should have the remote A&E query PC time synchronized with the PC you are running the DSC engine. And on both computer
you need to run the NI Services (ClassAds, Citadel, Time Sychronisation)

You can also use the A&E ActiveX control. There you need to subscribe to the running remote process. - Sure, these are just live alarms from this running remote DSC Engine and not histirical alarms.

Hope this helps.
