Hi @electrofasa21,
I tried to reproduce the issue with a clean new AS4.12 installation and a X20CP1484, but on my test system, everything including search for PLC worked as expected.
So I’m relatively sure, there’s something “damaged” in the Automation Software installation on your system, or some security mechanisms like antivirus, code execution prevention, insufficent user rights or similar functionality prevent the “search for plc” function.
To figure this out, could you please go trough the following test?
FIrst, I recommend to reinstall PVI in the actual version.
PVI setup is part of the PVI Development Setup which can be downloaded here in the actual version 4.12.5.34.
It’s sufficient to install it with default setting activated, please ensure that “Install PVI Manager as service” is unchecked! I want to ensure that PVI manager is installed as process, not as service.
Are there any error messages / popups shown while installation?
Second, it would be very interesting if PVI manager is stopped directly after startup, or stops after using “search for plc”. Th check this, please close all open windows inside Automation Studio project first, especially the “online → settings” window (closing the windows prevent that after re-opeing the project, the windows are opened automatically and function “search for plc” starts automatically).
After closing closing all project windows, please close Automation Studio. Then, open it again without opening anything else inside Automation Studio, then open the PVI Monitor (the PVI Manager window) → is PVI Manager already in “stop”, or does it more look like in the following screenshot?
Third, leave the PVI window open, and execute a “search for plc” in Automation Studio → is the PVI manager now stopping immediately?
If not and it works now as expected, we’re done here, no need to have a look in the following information!
But if the behavior is still the same, it could be interesting to get an information of some software versions installed on your system.
Please check if you have a folder “npcap” inside your windows “programs” folder, and provide us the version of “npcap.sys” (right click → properties) … don’t wonder if your version is different to the one from the screenshot below, this is possible and could be ok, I’m only interested in the version number in general.
Also, please provide us the version of “brsnmp.dll” inside the PVI installation folder (by default, it’s C:\BrAutomation\PVI\V4.12\Bin).
And last but not least: please check your antivirus- and code execution prevention-systems and the windows event logs for messages pointing into the direction that some functions / installations were prevented / suspressed!
To be honest, I’ve no more other idea why the function doesn’t work on your system, but on my systems it works flawless using exactly the same software and hardware setup.
Best regards, and have a nice weekend!
