Hi
I’m testing device with PMU. I can connect to it via Connection tester (connection via UDP).
I’ve saved connection and config to use it with openPDC manager.
openPDC manager connects to the service (green light).
During configuration request it shows error
but i can create device using saved data from connection tester.
But unfortunately i can not see any date from connected PMU.
all PMU data are visible on wireshark.
could you help me to solve connection problem?
Hi rudypiotrek,
Based on the WireShark capture, it looks to me like 192.168.2.252 is the PMU’s IP address. Therefore, you should be using either interface=192.168.2.250 or interface=0.0.0.0 in your connection string.
Thanks,
Stephen
sorry - my bad
I’ve change to the correct one
and I’ve tested with 0.0.0.0 too, with the same results
it shows communication establish but nothing is displayed and stream statistics I can see that system is green but device has red light
in error log i have all the time this:
System.ArgumentNullException: Value cannot be null.
Parameter name: value
at GSF.ServiceProcess.ClientHelper.set_SecurePassword(SecureString value)
at GSF.TimeSeries.UI.CommonFunctions.<>c.b__57_0(Object state)
In that case, my best guess is Windows Firewall. You were likely prompted by Windows to bypass the firewall when using PMU Connection Tester because it is an interactive GUI app, but the same courtesy doesn’t apply to Windows services. You would need to add the firewall rule manually.
Thanks for info
I’ll try to do it and I’ll let you know.
it works 
I’ve added separate rule for firewall for required port and i can see stream
thaks again
Hi.
One question.
Now i can receive PMU stream and it is displayed on graph as on figure above. Buf if I switch to Stream statistics System is in GREEN but input stream is still in RED. Is it intentional for UDP or something is still not ok?
I set up a test using UDP to verify, and it seems my input stream does turn green.
You can see in the screenshot that I have highlighted the relevant statistic: Input Stream Connected. If that statistic is False, the input stream will remain red on the display. So if yours is remaining red despite the fact that you are receiving data from the source device over UDP, it could mean that your statistics are misconfigured somehow.
Hi
Input Stream is connected on my side too, but stream stays RED
as I can see the CFG1, 2, 3 frames are received every 60 sec. Does it matter?
Or it is RED because Configuration is out of Sync
If you are receiving data, then why are your Measurements Received and Total Frames stats both zero? Is this the same input stream that is receiving data in your previous screenshot?
