RTEJMJ — Tue, 21 May 2013 16:25:04 GMT

Hello , i create an historian .csv. But i have this error in the file statuslog and i have no archive. :

[21/05/2013 16:38:33] [CSVHISTO] Attempting connection...
[21/05/2013 16:38:33] [CSVHISTO] Connection attempt failed: The process cannot access the file 'C:\Windows\system32\measurements.csv' because it is being used by another process.
[21/05/2013 16:38:33] [CSVHISTO] Exception occured during disconnect: Object reference not set to an instance of an object.

CSVHISTO is the nema of the historian.
I dont know what can i do.
Thank you.

New Post: Historian Web Service no longer returning good data

patpentz — Mon, 20 May 2013 20:19:41 GMT

This is a test openPDC, so I stopped it, and deleted all Archive and Statistics files. Upon restart these files were recreated. The historian statistics metadata look correct, as far as I can tell from a brief inspection. The metadata show the system and concentrator statistics from id=1 to 35, and then a gap until id=957 for the first non-concentrator statistics.

When I use the Historian View, the statistics look good. However, when I use the web service, the data remains as before (Unknown, very old, 0.0). This is true when I use the web service manually from a browser.

I normally use the web service via a program, and didn't notice when the data went bad. It certainly worked fine at some unknown time. Non statistics data still arrives in good form.

New Post: Flat Line test with a public smtp server

I'm configuring a Flatline Test adapter, but I don't have a smtp server in my computer. Is it possible to configure a flatline adapter with a public smtp server, like gmail?

Thank you
Paulo André

Here's a few things you can try:

(1) Check disk space on where historian data files are located (by default, ...\Program Files\openPDC\Archive) - a full disk can cause this error
(2) Stop the openPDC service then delete *_dbase.dat, *_startup.dat and scratch.dat (i.e., anything but a ".D" file) in the archive folder restart PDC and see if the historian service returns to normal operation? This deletes the non-data related files that may become corrupted due to an improper shutdown or other activity - these will be recreated once the PDC restarts - then you can try the tool again.
(3) If these steps do not work, one of your recent ".D" files may be corrupted (e.g., ppa_archive.d) and may need to be deleted - back up all files before deletion of ANY .D files so you do not lose an historical data.
(4) Also be sure to validate the timestamp of the incoming measurement data and make sure it is good quality and a reasonable time.

I am no longer getting good data from the Historian Web Service (Statistics) at:

every value is Quality: Unknown ReceivedTime: 1/1/1995 12:00:00 AM value: 0.0

1) Fixed the registry keys in the installer. 2) In ConfigurationSetupUtility, added code to log exceptions to the error log on the SetupInProgressScreen.

Synchrophasor-VS2012: 1) Fixed dependencies for the InstallerActions project. 2) Added post-build event to the openPDC project to copy the tools that exist in the openPDCSetup folder to the output directory.

New Post: TRANSFER A CALCULATED MEASUTEMT BY OUTPUTSTREAM

kevinjones — Sat, 18 May 2013 16:41:34 GMT

I have never been able to do it directly (although I think you can). What I do is map all of my calculated values to a virtual device and the. Add the device to the output stream. Works like a charm.

Hi!

I created a new measurement by an action adapter and I would like to transfer this measurement through an OutputStream to other remote computer. Is it possible to make this implementation? if it's possible, how Can I do it?

regards,

Itan

New Post: Alarm when signal is NaN

patpentz — Thu, 16 May 2013 16:29:38 GMT

I need to test for a few signals that might be 'NaN'. The values must be both non-zero and non-NaN; would a test for zero work in this case, so that an alarm is raised for either zero value or NaN value.

Otherwise I would have to create a DynamicCalculator that test for these values, outputing a boolean signal which could be alarmed. I hope to avoid this second step.

New Post: PowerCalculation Stopped Working

This and many other adapter problems occurred when the Time Domain service stopped working. OpenPDC is very dependent on good time!!!

New Post: DynamicCalculation Parse Errors - How to prevent?

patpentz — Tue, 14 May 2013 17:20:12 GMT

I found my reference as to how to make double.IsNan to DynamicCalculator. Add as import:

AssemblyName={mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089}, TypeName=System.Math;AssemblyName={mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089}, TypeName=System.Double

I would recommend that this assembly be make always available, since NaN's will become more prevalent.
